State of the Fleet

We'd like to welcome our newest addition, ZS-IDL, a Cessna 150 to our fleet. The plane has had a new engine put in, a new prop fitted and has been stripped down and re-painted. She also has a new interior, and will be ready for hire & fly and ab-initio training once the final paperwork has been completed. Watch this space.
  • ZS-IDL (Cessna 150)
    Awaiting paperwork.

  • ZS-KFV (Piper Tomahawk)
    OK. Going for MPI on Monday 1 October, and should be back by Wednesday 3 October.

  • ZS-KKC (Piper Tomahawk)
    OK. Recently returned from some repair work to the undercarriage.

  • ZS-KKU (Piper Tomahawk)
    Grounded (cracked crank case).
    The engine has been removed and is in JHB being repaired. This should take about 3 weeks so the plane should be back in service in about 4 weeks time. Hold thumbs.

  • ZS-PIA (Piper Tomahawk)
    OK.

  • ZS-KBK (Piper Warrior)
    OK. New engine arriving in a few weeks,
    and then she will be down for a week while it is changed over.

  • ZS-JDN (Cessna Skyhawk)
    OK.

  • ZS-PMY (Cessna Cutlass)
    OK.

  • ZS-KSS (Cessna Cutlass)
    OK.
Fleet Upgrade

With regards to the upgrading of our fleet, we are very interested in hearing from JOE PILOT as to what course we should be following. The questions are as follows:
  1. Do we stay with Certified planes or change over to Non Type Certified.
  2. Leading on from that is which planes do we use for either.
  3. The last questions how to finance the upgrade.
So far the instructors favour the Tomahawks or Cessna 172's as basic trainers and the RV9 in the NTC class. We think that it is advisable to move away from the Tomahawks as they are getting very old and costly to maintain and there are not that many flying anymore. Please e-mail either Bev at the club (info@capetownflyingclub.co.za) or David Barnes at actyot@iafrica.com.


ATC flip day round 2

Saturday the 20th October is International Day of the Air Traffic Controller.
To celebrate this day, CTFC will be hosting an ATC flip day.
(If you recall, the last one was rained out earlier this year...the weather WILL be perfect this time!)

The idea is to take the controllers and assistants flying from 12-2, and then braai/party after.

If you can help in anyway, be it flying or braai-ing or anything in between, please let Gareth know. (email: garethpinnock@gmail.com)


Overberg Fly In: Booking sheets

As previously stated, there will be no minimum hour requirement for planes going to the
TFDC Overberg Fly In (including the Tomahawks). Bookings will take place on a first come, first serve basis and the booking sheets for the event should be accessible on the 12th of October. For more information on the event please visit www.flyin.org.za.


End of year function

Beverley needs numbers for catering purposes for the year end function ASAP. The year end function is on the 24th November and we will be having a spit braai which is the best you will ever taste. Of course this does cost money and the club will be sponsoring a portion but tickets can be purchased at R50-00 per head.

Confirm you're coming either by phone (021 934 0257) or email (info@capetownflyingclub.co.za).

Prizes/sponsorships


Vossie needs our help with the donation of prizes and sponsorships towards the cost of the event. If you can help, or would like to be involved in the organising, drop Vossie an email on geminimotors@telkomsa.net.

Courses & English Language Proficiency Rating

DEAL ALLIANCE will be offering the following courses at the Cape Town International airport at the Cape Town Flying Club premises:
  • Commercial Pilot Course
    From 8 October 2007 @ 0700 - 1300
  • Airline Pilot Course
    From 15 October 2007 @ 1730 - 2200
Aviation English Language Proficiency Rating

All SA pilots will need to do the Aviation English Language Proficiency Rating with their next licence renewal or by the 15 December unless they provide proof of English first or second language at Matric level. In this case they will automatically be given a Level 5 Rating which is renewable in 6 years time. If they do the Interview with a Test Centre, however and are rated as Level 6 speakers, they will not have to do a Rating ever again. Deal Alliance is the Approved Test Centre here in the Cape. The Interviews cost R700.00 and are held at Signature Flight Support.

December Courses

Deal Alliance will be offering an Initial CRM (2 days), or refresher (1 day) followed by "Dangerous Goods" (1 day). Then they will also be offering a general radio licence test and the language proficiency rating (See above). This will all take place in the week of the 10th December. From next year, this will be offered on a regular basis.

Further details on the Pilot Ground Schools for this year and on the Language Proficiency Ratings can be obtained from either Vanessa or Deborah on the following cell numbers:

Incidents & Accidents

The importance of a thorough pre-flight
by Danny Buitendag



An Aeroperu Boeing 757 crashed into the ocean less than 30 minutes after taking off from Lima, Peru in 1996. Pieces of duct tape placed by maintenance personnel, were found covering sensors, causing the malfunction of instruments. The crew was not able to correctly determine their altitude and airspeed and with no ground reference over water and at night, crashed into the ocean. Although a maintenance worker was tried for negligent homicide for failing to remove the adhesive tape (he received 2 years in jail), who did the preflight?


How not to fly your Airbus

http://www.youtube.com/watch?v=rYfhC9ft_hk

This footage if from a recent airshow in Portugal. The Airbus A310's wingtip comes dangerously close to the ground during a very low altitude pass!


Lucky Escape



This man is Robert Robertson, a 34 year-old pilot who miraculously escaped a crash. His Beech 18 ran into trouble shortly after takeoff and came down on a highway in Florida, US. As the aircraft was ripped apart all around him, Mr Robertson managed to stay in one piece, with only a broken leg, arm and nose.



Living dangerously - VFR flight into IMC
by Gareth Pinnock


http://www.alexisparkinn.com/photogallery/Videos/flightassist.mp3

The above MP3 (approximately 3MB big) is a recording of the exchange between a pilot flying VFR and a controller. The pilot has entered IMC, and loses control of his aircraft. Skip the first minute of the recording to hear the actual exchange. There can be little doubt that this pilot understands the true meaning of terror.

The following piece by an unknown author illustrates what this pilot has just experienced.

Here's the fatal scenario. . . . . . .



The sky is overcast and the visibility is poor. That reported 8km visibility looks more like 3, and you can't judge the height of the overcast. Your altimeter tells you that you are at 1500 feet but your map tells you that there's local terrain as high as 1200 feet. There might be a tower nearby because you're not sure how far off course you are. But you've flown into worse weather than this, so you press on.



You unintentionally ease back just a bit on the controls to clear those towers. Without any warning, you're in the soup. You peer so hard into the milky white mist that your eyes hurt. You fight the feeling in your stomach. You try to swallow, only to find your mouth dry. Now you realize you should have waited for better weather. The appointment was important, but not all that important. Somewhere a voice is saying, "You've had it -- it's all over!"


You now have 178 seconds to live.

Your aircraft feels on even keel but your compass turns slowly. You push a little rudder and add a little pressure on the controls to stop the turn but this feels unnatural and you return the controls to their original position. This feels better but now your compass is turning a little faster and your airspeed is increasing slightly. You scan your instruments for help, but what you see looks somewhat unfamiliar. You're sure that this is just a bad spot. You'll break out in a few minutes. (Only problem is you don't have a few minutes left.)

You now have 100 seconds to live.

You glance at your altimeter and you are shocked to see it unwinding. You're already down to 1200 feet. Instinctively, you pull back on the controls but the altimeter still unwinds. The engine RPM gauge is in the red and the airspeed, nearly so.

You have 45 seconds to live.

Now you're sweating and shaking. There must be something wrong with the controls; pulling back only moves the airspeed indicator further into the red. You can hear the wind tearing at the aircraft.

You are about to meet your Maker; you have 10 seconds to live. Suddenly you see the ground. The trees rush up at you. You can see the horizon if you turn your head far enough but it's at a weird angle -- you're almost inverted. You open your mouth to scream but. . . .

. . . .you just ran out of seconds.

Continuing into IMC conditions continues to claim lives. Remember, statistics show that accidents involving weather as a contributing factor have an 80% fatality rate.

Does it seem hard to believe that one tends to ignore the instruments in scenarios like this? We try to overcome a lifetime of listening to and trusting our bodies by doing a few hours (40 in the case of an instrument rated pilot) instrument training.

Our brain is the biggest culprit. Look at the picture below. Which shapes are moving?


Actually, none of them are moving. Our brain misinterprets what the eyes are telling us. The brain can also misinterpret other visual cues. Just think back to when you were last at a stop street and the car next to you started moving – for a few seconds you may have had the feeling that you were moving backwards. The ease with which the brain can be fooled gets VFR pilots killed in IMC. For some of the illusions, visit: http://www.rjma.com/flight/airwaves/in_flight_illusions.htm

The CAA regulations state that a pilot may not take off when the weather along his/her planned route is below the VFR minima, and yet many pilots still take off in the hope that things will improve. The disease called “get-home-itis” is in many cases fatal, and at best leads to breaking the law by “scud running” at low level, or at worst to your first and last acquaintance with the “graveyard spiral.”

And IMC at night?

It is interesting to note that the CAA wanted to make auto pilots compulsory for all VFR night flights back in 2003.

AIC 23-2 states:

The attention of all pilots is therefore again drawn to the fact that a take-off at night from certain aerodromes which are situated away from towns or cities or other surface light sources, may well be considered as an IFR take-off when no clearly discernible horizon is visible from the cockpit or flight deck. This may apply on a particularly dark, moonless night or on a night with overcast sky and it may also apply only in certain directions of take-off.

And read in conjunction with AIC 40-4:

The Civil Aviation Regulations do not forbid VFR flight by night, however, irrespective of the weather, ATC’s should encourage all flights capable of operating under the IFR and intending to operate in any controlled or advisory airspace, except flights which do not intend leaving the aerodrome traffic circuit, to operate under the IFR.

The proposal for autopilots was scrapped, thanks to the tireless work of SAPFA(South African Powered Flight Association):
(http://www.sapfa.org.za/pdf_files/SAPFApart91.pdf)

We understand that there have been a number of fatal accidents at night but our information is that these tend to be in the take off or landing stages of the flight when the auto pilot will be disconnected. There have also been instances of controlled flight into terrain. In these instances it appears that the accidents were due to misidentification of terrain as airspace and once again access to an auto pilot would not have prevented an accident.

Looking at the CAA's original proposal, and reading the two AICs, the message from the CAA is clear: the challenges facing a VFR only pilot do not only occur in bad weather.

We owe it to our family and passengers to be aware of the challenges, as well as having the capability to face those challenges when they arise. It is up to the PIC to ensure that he/she has had adequate training recently enough – not necessarily by the legal definition only, but rather by your own definition of what you think makes a safe, current and capable pilot.


Aviation News: Cessna's Jet Sales Taking Off



The head of Textron Inc.'s Cessna Aircraft Co. said the airplane manufacturer's backlog stands at $11 billion - the most in eight decades of operation - as business jet orders and deliveries continue to grow.

Jack J. Pelton, chairman, president and CEO of Cessna said in a statement the company had orders for 2,700 units on its books as of Aug. 31. Half of those are Citation-model business jets.

So far this year, Cessna has secured orders for 525 business jets, compared with 496 during all 12 months last year, the company said.

Speaking at an industry conference, Pelton said Cessna plans to deliver 380 business jets this year, up from 307 last year. The company plans to deliver 470 in 2008, he said.

"This extraordinary rate of growth is being driven by strong economies and corporate profits and a rapidly emerging global marketplace," he said. "Clearly, our strategy of having the broadest, most comprehensive product line in the industry is serving us well."



Aviation Fun: Jeremy Clarkson on Flying
STOLEN FROM TIMESONLINE

Last weekend, a friend of mine was killed when his helicopter crashed in Scotland. And then, just hours later, another friend was lucky to walk away when his chopper flipped onto its side while making an emergency landing in Essex.

Strangely, however, it’s not a fear of dying that puts me off the idea of private aviation. It’s the surefire knowledge that nothing in all the world is likely to be quite so boring and pointless.

The idea of piloting your own helicopter or light aircraft, among the clouds and the linnets, far above the jams and the pressure, is an appealing prospect for anyone who doesn’t know what to do with his money.

Better still, you might imagine that you could enliven your journey by swooping underneath low bridges, divebombing fields of cattle, looping the loop over friends’ houses and landing for the hell of it in beauty spots and bird sanctuaries.

Only last month, I flew down the Okavango River in Botswana in a twin-engined light aircraft; following the waterway’s endless twists and turns just 6ft up, at 150mph. It was a joyous and brilliant thing to do. But unfortunately, if you tried that at home, skimming the Don in Sheffield, for instance, a man with adenoids and a clipboard would come round and take your licence away.

In fact, the whole process of learning to fly, it seems to me, is designed specifically to weed out those who might want a plane or a helicopter for fun.

When you want a driving licence, all you have to do is demonstrate to a man in beige trousers that you can reverse round a corner. But when you want a licence to fly, you must demonstrate to the entire Civil Aviation Authority that you are prepared to spend several months with your nose in various text books on meteorology and aerodynamics. Plainly, it only wants pedants up there.

Then you have to spend more months learning how to use a radio. Why? I know already. You just stab away at various buttons until someone comes over the speaker. Then you tell him what you want.

Oh no you don’t. You have to talk in a stupid code, saying “over” when you’ve finished speaking for the moment and “out” when you’ve finished altogether. Why? When I ring the plumber or the local Indian restaurant, I am able to convey the nature of my request perfectly well using English. So why when I’m in a plane do I have to talk in gibberish?

“Hello, it’s Jeremy. Is it all right to land?” is a much easier way of saying, “Weston Tower, this is Charlie Victor Tango on 8453.113 requesting a westerly approach to runway 27.”

But private pilots love all this sort of stuff. They love doing utterly pointless preflight checks, tapping dials and making sure that a bunch of goblins didn’t come in the night and chew through all the wires.

They never think: “I bought this plane to make my life more convenient but in the time I’ve spent checking it, I could have driven to Leeds.” And nor do they ever think: “If these checks are so foolproof, how come that in the western United States, more small planes fall out of the sky than rain drops.”

No really. In America, more than one person a day is killed in private plane crashes. Light aircraft, over there, are known as “dentist killers”.

And try this for size. You don’t have to check your plane if you leave it alone for a few hours in the day. But you do if it’s been left alone at night. Why? Do the plane goblins only come out when it’s dark? No. Will a comprehensive preflight check keep your plane in the air? No. The fact is that pilots love checking things. They love details.

I know this from glancing at the magazines they read. Boat magazines are full of boats skimming the waves with naked girls on the foredeck. But plane magazines are filled with lists of serial numbers and adverts for stuff that no one could conceivably ever want to buy. Quarter-scale cockpit models, for instance. And hideous pictures of Lancasters, at sunset, over Dresden.

Just last night, I spent some time in the company of two private plane enthusiasts who never once talked about the speed of their machines or the convenience, or the sheer, unbridled fun of skimming the treetops at 150mph. Instead, they talked for hours about parking and refuelling. I bet they think the best bit of sex is unwrapping the condom.

Certainly, they seem to have a weird love for the medical, which they must take every 15 minutes. I can’t see why this is necessary because medicals cannot predict a heart attack, which is about the only thing that will affect someone’s ability to fly a plane.

And you know what. Hardly anyone with a plane ever uses it to go somewhere useful. Instead, they take “the old kite” from their flying club headquarters to another flying club headquarters where they have some cheese and Branston pickle. And then they fly home again. What’s that all about?

And while they’re flying around, spoiling the peace and quiet for everyone on the ground, they are having absolutely no fun whatsoever. This is because they are at 3,000ft, where 100mph feels like you’re standing still. And they can’t come down low for fear of the man with adenoids.

So, the recipe for flying then. You drive to an airfield, check your plane for two hours, take off, sit still, speak gibberish into a radio, land, eat cheese and then sit still again till you’re home again. Repeat until one day you hear a loud bang . . .

Chairman's Report --> Alexia Michaelides

Greetings fellow members.

I am happy to report that things at the club are ticking along very nicely and thrilled to see ZS-PIA flying again with its small problem finally sorted out. We have two aircraft coming up for new engines, but KBK should be quite quick as the engine has already been ordered. KKU is another story and we are not sure at this stage how long she will be out of action.

Please note that we have some great functions coming up now for Spring, and Vossie and David Wilson will keep you posted regarding dates for next party as well as the Year End Function. Keep an eye on the newsletter for information regarding the Overberg Air Show and Fly-Away. Bookings are not as yet open for that period, and no advance bookings will be possible. This will be done on a "first come first served" basis as per the on-line booking system which is the fair way to do things.

I am making yet another appeal for all new members to come and greet the committee prior to the next committee meeting. The next meeting will be on the 15 October and all new members who have not yet met the committee members are encouraged to come and have a drink with us. We usually meet just before 6pm. We really would love to meet all new members.

David Barnes has some great new ideas for the Pilot shop so keep a look out for the "big reveal" in a few weeks time.

Summer is coming and the shortage of aircraft is being addressed. We will be leasing ZS-IDL, available almost immediately (we are just waiting for insurance cover), and this C150 will be available for hire 'n fly as well as ab-initio training, and we have an option to lease ZS-POX as well, but this has not yet been confirmed.

The decision regarding the new fleet has already been discussed with the instructors. I will be opening the discussion up to the entire membership very shortly and everyone is encouraged to voice their opinion, suggestions etc. All suggestions etc should be in writing and if possible, give your reasons for your recommendations. We will be devising a way to collate everyone's ideas, but in the meantime I have given you food for thought.......

Safe flying to you all

When things go bump in the front --> Tony Beamish

I have the pleasure of being the caretaker of ZS-MAM, a 1976 Seneca II. MAM was fitted with fabulous avionics in 2005 and has long legs. On 18 May 2007 I took my American cousin to Namibia for a visit.















Having departed Cape Town at exactly 11h00 for Lüderitz we climbed to FL105 and at 11h23 set the aircraft up for the cruise on our 470 mile three hour flight on a beautiful day.

MAM has a JP Instruments EDM-760 Engine Graphic Monitor. See: www.jpinstruments.com and (www.jpinstruments.com/edm_twin.html. I won’t elaborate here on the functions of the EDM-760 as you will see this from the links provided except to say that when EGT, CHT, TIT, Oil Temperature, Battery Voltage or Engine Cooling is outside of Piper’s parameters the aural warning certainly lets one know.

















1 hour and 59 minutes into the cruise a slight jolt to the left was felt. My immediate thought was that there was a turbocharger problem. Two years ago a clamp on the induction side of the turbocharger came adrift in the cruise and this appeared to be a repeat of what I had experienced before. There was no aural warning but a scan of the steam gages – yes, we still rely on those – revealed a drop in the left engine’s manifold pressure from the 31,7 inches cruise setting. There was no noticeable decrease in oil pressure or increase in oil temperature, so no need in my mind to declare an emergency. Simply invoke some rudder trim and proceed a few knots slower. (Part of my Seneca training focused on the fact that one might experience a partial loss of power as opposed to a total power loss. Another aspect of my training was in those circumstances to nurse the ‘good’ engine.)

ZS-MAM is approaching the ‘ouch’ expenditure stage with two factory remanufactured engines to be ordered in 2008. The Teledyne Continental TSIO-360-E’s have a 1,400 hours TBO and are in their ‘second life’ at 2,700+ and are almost time expired. Factory remans – the only Seneca option right now – come at R290,000 each. (New engines are also an option.) Fortunately the new engine have a TBO of 1,900 hours.

Anyhow, we landed safely in Lüderitz and continued our trip on Air Namibia. Westair Maintenance in Windhoek Eros was retained to fly to Lüderitz with an engineer and a Seneca pilot. It was found that the number three cylinder head had separated from the cylinder. A loaner number three cylinder was installed and MAM was flown by a Westair pilot from Lüderitz to Windhoek Eros. (Apparently there are few South African CAA commercially licensed Seneca pilots around Namibia).

At Eros the cylinder was replaced with a serviceable unit but the engineers still experienced a rough engine. After investigating they found that the number four cylinder had severe carbon deposits in the rockerbox. They removed the cylinder and found the exhaust valve guide worn beyond limits. (See the pictures).






















































TREND MONITORING

One perceived benefit of engine graphic monitors is the ability to predict a problem before it occurs. Why was there no aural warning in the time leading to the cylinder failure? Why was there no aural warning after the cylinder head had parted company with the cylinder? There were no exceedences in the monitored parameters either before or after the failure. There was also no oil noticeable on the cowl in flight.

Engine Graphic Trend Monitoring in piston engines is, in my view, in its infancy. The engine monitoring software provided by JP Instruments (and downloaded free of charge from their website) is rudimentary yet adequate but not nearly as good as the EG Trends software – whose byline is “Preflight the inside of your engine™”. Their website is: www.egtrends.com. I first saw their software on display at Oshkosh in 2005 but didn’t buy it. I have now placed my order.






























ENGINE MAINTENANCE

One really doesn’t wish to throw money at an engine which is on its last 100 hours of useful life and so I hope things run smoothly until the engine Lotto is won – which must be in the next twelve months.

I traced ZS-MAM’s MPI history back to 1992. I started flying the aircraft in 2004. From 1992 to 1999 it flew 390.2 hours (an average of 55,7 hours per annum) and from 1999 to 2004 it only flew 16 hours (an average of 3,2 hours per annum). I have flown MAM in excess of 300 hours between November 2004 and September 2007. There are engine and airframe maintenance issues in not flying an aircraft frequently. Teledyne Continental tells one: “As a general rule, changing your oil at least every 50 hours of operation and flying your aircraft at least once a week will go a long way in preventing internal corrosion and its associated maintenance headaches. If your aircraft is based in an extremely corrosive environment (i.e. high humidity, near the seashore, etc.) or in extremely favourable anti-corrosive area (stable temperatures, low humidity, desert like conditions, etc.) these intervals can be adjusted accordingly but as a rule of thumb they are a pretty good guideline for preventing excessive internal engine corrosion and the unexpected maintenance costs caused by it.”

I am not inferring necessarily that there is a causal link between the lack of use and the severe carbon deposits in the rockerbox of the number four cylinder but the engine manufacturers cannot preclude that possibility. I belong to the Piper Owner Society (www.piperowner.org) and they approached the engine manufacturer Teledyne Continental (www.tcmlink.com) on my behalf with my research into the MPI history together with the engine graphic monitor stats and usage information. There were no exceedences during my tenure as pilot of ZS-MAM except for the shock cooling warning that has occasionally occurred on final approach for landing.

If anyone would like to play around with ZS-MAM’s engine monitor graphs then go to www.jpitech.com/1body_downloads.php4 and download EzPlot or EzTrends and then e-mail me and I will forward my flight data files to you.

Crash Pilot Allegedly Attacked by Angry Commuters --> Avweb.com (submitted by A Russel)

The South African media is sorting out the facts after at least one news outlet reported that the occupants of a vehicle hit by a Tiger Moth in an accident on a road south of Johannesburg Wednesday attacked the injured pilot while he was still strapped into his seat. The pilot, Glen Simpson, is reportedly doing well in hospital but the crash killed his passenger and the driver of a bus that was struck by the plane. One other vehicle was also hit and a total of 23 people were injured, most of them on the bus, which carried 40 people. There's some question whether the attack actually took place, however.

The Independent said Simpson's parents were unaware that any beating took place but quoted 702 Eyewitness News as saying: "His father Mike told 702 Eyewitness News that angry commuters started kicking Simpson after the accident, while he was still strapped to his seat. A witness confirmed that commuters had attacked the injured pilot." The spectacular accident is naturally being investigated by a long list of authorities.

In 1939 she achieves a woman’s altitude record of 30,052 feet over Palm Springs, California in a Beechcraft Model 17. And in 1953, Jacqueline becomes the first woman to fly faster than the speed of sound while flying a Canadian-built North American F-86 Sabre. On the same day, she sets the world speed record for women at 652 mph (1,049 kmh). In 1963, at Edwards Air Force Base, California, Jacquiline also sets a 100-km closed-circuit world speed record for women of 1,203.7mph in a Lockheed Starfighter.
