    I think this is the crash that occured at Gimli Industrial Airpark in Manitoba, Canada. The aircraft is a highly modified Caribou, converted to turbine power and operated under the Experimental catagory of CAR 4b. It had flown the year prior to the crash. . The complete report can be found starting on page 6 of a PDF file at this website... _http://www.asasi.org/papers/2001/Four%20Unrelated%20Accidents.pdf_ (http://www.asasi.org/papers/2001/Four%20Unrelated%20Accidents.pdf)

    laval.com> Hans-- I'm glad you landed safely and have determined the cause of your fuel starvation problem. Excuse my continual endorsement of the four-book series written by Tony Bingelis, but he shows all types of fuel flow installations and knows the do's and don't that are easily done without doing some valuable reading first. I can't help but recommend a nose-tank only for any kind of Pietenpol with any kind of powerplant. You have the most simple of designs with very short tubing/flexible tubing runs, a single shutoff valve, a gascolator, and vented cap. You can fit 17 gallons there too if you design it to fit the curved upper portion, just under your aluminum cockpit cowling area. With the nose tank you free up the entire center section for camping or any other kind of gear. In my center section I can fit my tent, sleeping air pad, cloth folding chair, tie downs, spare oil, Marvel oil, and rags. It also makes for an excellent way to easily inspect your aileron balance cable, turnbuckle, and two aileron pullies. With most Piets having tail-heavy syndrome, if you put your fuel just behind the firewall instead of the cc, you help yoursefl in the CG department. The nose tank is easier to fill too....and if you spill some it doesn't run down and drip on the pilot seat like a cc tank fill job can do. Just some thoughts ! Simpler= lighter. Lighter= better performance and the ability to fly passengers without a pucker factor in the high 9's. Mike C.

    Subject: Anyone Know The Story Behind This Crash?
    --> Pietenpol-List message posted by: "Robert Gow" <rgow@avionicsdesign.ca> That's a real video of the crash of the first prototype Turbo Caribou. I think it was Winnipeg, but I don't remember anymore. The control locks were never removed before take-off. I didn't know them personally but they were friends-of friends that died in that crash. the project was picked up later and I was privileged to work on it. The STC to convert the Caribou to turbines is now held by Pen Turbo in the States. DECA Aviation in Toronto with some minor assistance form our company (Avionics Design Services) finished off the program.

Almost looks like an RC model especially given the cameraman's rather unemotional comment following the crash. Kind of looks like the elevator may have been hooked up backwards following a rebuild. http://media4.big-boys.com/content/oldplanecrash.wmv Any information on this video would be intersting.

Now after this and a few times having to fill to CC tank I am considering it again. It still can easily be done although it would be more work as CG will change forward. Filling the CC tank is real pain and spillage risk is high, did not happen to me yet but I am sure Murphy's law will rule on this to. Plus that Tank sitting above you during a more damaging emergency landing is potential for being soaked in gas Hans

    --> Pietenpol-List message posted by: lshutks@webtv.net (Leon Stefan) Good thoughts Mike. Unfortunately Model A builders like me are stuck with the wing tank because of the high location of the Model A"s carb. My carb. sets at the same height as the top of the fus. cowl. eliminating gravity flow. Leon S. In hurricane free Kansas.

    The Travel Air uses 30x5 wheels. The shock cord attaches to the axle and center vee, unlike a Cub where the shock cord is entirely on the axle "spreader bar." I could come up with measurements for the Travel Air if anyone thought it would be useful, but I doubt it.

It will take some drafting time to figure axle placement and landing gear angles for the right deck angle.

If so, are there any special considerations about that (wheel dimensions limits, side loads, etc.) I like the look of the spoked wheels, but the impact absorbtion, strength and utility of the split axle sure looks more attractive. I'd miss those beautiful ash struts though. Phil Miller PietenVair Altadena,CA

    Subject: Re: light, simple, mindless fuel tank installations
    laval.com> Jack-- I have no baffles in my tank. There are enough bends in that back piece that it doesn't oil can and the bottom is supported by two pieces of spruce running side to side with s/s fuel tank straps w/ felt glued to them cradling in the whole thing. Good thoughts on the fuel above you during an accident, Hans. William Wynne had a really neat idea of making his cc out of fiberglass and using it as a structural member if I'm not mistaken....but that was also the cause of his burns after he had some carb ice and a forced landing. A really great guy---hated to see that happen. Lesson learned from all of these stories. Some have asked if I get enough head pressure with my tank being all in the nose and I performed flow testing ala the Bingelis HP/min-flow-in-a-climb angle at the carb and I had the required flow all the way down to just under 2 gallons. So to fly safely full power in a climb, I need at least two gallons of fuel in the tank or more. Not bad to have a useful load of 15 gallons on board in a Piet. Mike C.

    From: harvey.rule@bell.ca
    --> Pietenpol-List message posted by: harvey.rule@bell.ca Ok ,I stand corrected.In my situation I have the shut of valve directly below the tank with the connection going out to the gascolator with no flex tube in it as per an AME and I have yet to test mine.I am also having more of a problem trying to connect up the shut off cable because the valve is facing 90 degrees from where yours is and I have to find somewhere on the side to mount that cable and high enough so it can still shut off the valve. It does give me an idea though,I can still turn my valve around 90 degrees and still have the lower connection connected up the same.Thanks for the picture.I may still land up putting the flex tube it yet.I have a short piece going from the gascolator to the carb as it stands right now. -----Original Message----- From: owner-pietenpol-list-server@matronics.com [mailto:owner-pietenpol-list-server@matronics.com] On Behalf Of Michael D Cuy Subject: Pietenpol-List: flex hose under tank --> Pietenpol-List message posted by: Michael D Cuy <Michael.D.Cuy@grc.nasa.gov> Harvey-- if I turned that fitting around I'd not have had room for my shutoff valve and a flex hose works to dampen vibration if in a loop or semi-loop as I have it installed.

It was such a short run that I couldn't get it right-- could not get the tube in the flaring tool after I did one end. I hear you on the actuator problem too on your valve orientation. You can do it though ! ;You know my IA was watching me toil with that short tubing connection and HE was the one who suggested I turn that blasted fitting around and run/purchase a s/s braided flex hose to complete the run--and boy am I glad I did. I can't take credit for that installation idea, but it has worked like a charm. Don't forget to use fuel lube on all your threads/connections. It feels like thick bees wax....and if I'm not mistaken it just might be. I have some if you need it and can ship it to you via mail.

    --> Pietenpol-List message posted by: harvey.rule@bell.ca I can't take credit for that flared alluminum pipe either because it was already done when I got the plane.Yes sir I used fuel lube on all my connections even the ones at the flex hose and the AME said I didn't need to. He informed me on how sticky it is because he supplied me with some and your right it doesn't take much.He was very enfatic on the point of not getting it in the line too.If I can get that whole connection to move 90 degrees then I will fix my problem tonight after work.I figure I'll have to disconnect that alluminum tube first though.Oh boy another trip upside down and backwards while hanging on with my knees and one hand.I have bruises all up and down my one side from doing this acrobatic feat and I'm not amused.The guys at the field keep telling me I'm having fun!This plane building is interesting especially when most of its been done already and I have to go in and fix it or modify it after the fact.I have had to cut holes in the side of the aircraft just to install seat belts because they were not put in.Interesting way to build.I see now why the guy at the government office (when I went to apply for my registration) told me that I would have to dismantle the plane and start over again;maybe he had something there.I thought he was nuts at the time but I'm beginning to think maybe he was right.Having fun here in cold Canada;I use that term loosely! -----Original Message----- From: owner-pietenpol-list-server@matronics.com [mailto:owner-pietenpol-list-server@matronics.com] On Behalf Of Michael D Cuy Subject: RE: Pietenpol-List: flex hose under tank --> Pietenpol-List message posted by: Michael D Cuy <Michael.D.Cuy@grc.nasa.gov> Harvey-- you know I had the exact same setup as you describe on your tank and the reason I switched to the flex line is that I could not for the life of me make up that little line of alum. tubing with flares to match both my fuel valve and my firewall fitting !!!

    Subject: Re: Anyone Know The Story Behind This Crash?
    --> Pietenpol-List message posted by: Chris Cosentino <ccosenti@cisco.com> Hi Matt, I asked on one of the flight sim boards I frequent. Appears to be a full size De Havilland DHC-4T Caribou: Some people linked to this document (page 7 - page 6 in PDF), starting fourth paragraph) http://www.asasi.org/papers/2001/Four%20Unrelated%20Accidents.pdf The final example I?d like to bring before you today also deals with a modified aircraft. Like the first event I described, it?s unusual because virtually the entire accident sequence is captured on videotape. The accident occurred in August 1992 at the Gimli Industrial Park in Manitoba?a famous site in Canadian aviation history, where an Air Canada Boeing 767 known as the Gimli Glider was dead-sticked onto a drag racing strip, following fuel exhaustion. The accident aircraft is a highly modified de Havilland aircraft. In this case a Caribou had been converted to turbine power and was operated under the EXPERIMENTAL category of CAR 4b. The conversion was accomplished at Gimli, and the aircraft first flew in mid-November 1991, before accumulating about 23 hours on 12 flights by month end. These preliminary tests revealed the need for the replacement of the aircraft?s mechanical vacuum pumps with a Bendix suction system, the addition of in-line fuel boost pumps and the installation of a newly designed hydraulic pump. The accident occurred on August 27, 1992 on the first of several planned trips to flightcheck the fuel and hydraulic systems. The aircraft had been hangared in a partially disassembled state over the winter, and had only recently been re-assembled, including the re-installation of the complete tail section. I?ll let the video show you what happened?and I will caution you right now that this footage is extremely graphic? [Video?] The accident investigation used this videotape and some 35mm photographs as a key resource in determining what went wrong at Gimli. With the exception of a slightly higher-than-normal nose attitude at lift-off, the aircraft?s initial climb appeared normal. At about 35 feet AGL, the aircraft made a noticeable pitchup movement. When I tell you that the photography revealed that the elevator control surfaces were observed to pitch trailing-edge-up for rotation, neutralize and then remain in the neutral position through the balance of that short flight, I expect most of you will come to the same conclusion as the Transportation Safety Board of Canada. The aircraft?s control gust locks were at least partly engaged. A very close examination of the video does indicate rudder movement and minimal elevator movement, during the start of the takeoff roll. On the standard Caribou, the gust lock control handle is located forward of the power quadrant, and it has two positions?forward for Unlocked, and aft for Locked. If the control surfaces are not in the neutral position when the lock is engaged, any movement of the surfaces through the neutral position will cause the lock to engage. In addition, on the factory-standard Caribou, the control handle is designed so that when it is in the aft-Locked position, the power levers cannot be fully advanced. This is intended to prevent power application and takeoff when the gust lock system is engaged. The accident investigation further revealed that the aircraft?s takeoff distance was approximately 20 per cent longer than anticipated for the conditions. This may provide further evidence that the gust locks played a part in this event. Analysis of the recovered debris indicated that, although the aileron and elevator locking mechanisms were in their respective Disengaged positions, the rudder locking mechanism was found to have been in the fully engaged position at impact. Further investigation revealed that in fact, it had been jammed there by the forces of the impact. In addition, the analysis determined from the damage evidence that the aileron control lock had been dis-engaged at the time of impact. In its synopsis of the accident, the Transportation Safety Board concluded that the control gust lock system had not been fully disengaged prior to flight and that one or more of the locking pins had become re-engaged after lift-off. See also: http://aviation-safety.net/database/record.php?id=19920827-1 Narrative: The aircraft took off for a test flight for a turbine-engine conversion programme. It climbed steeply, rolled to the right and crashed in a nose-down, rightwing-low attitude. 3 fatalities Tuesday, August 30, 2005, 12:44:20 AM, dralle@matronics.com wrote: -->> Pietenpol-List message posted by: dralle@matronics.com (Matt Dralle) MD> Hi Listers, MD> Does anyone know the story behind this aircraft and the crash?

    Thank you , Gene , for pointing out the error of my ways! ;-] Give me a second to find a crayon so I can correct the Peter Westburg plans I was looking at! (not! ;-) The Travel Air 2000 (OX-5 powered) actually was spec'ed out with 26 x 4 wheels (I was wrong!!) -- The 30 x 5 showed up on the 4000 3-seat Biplanes & 6000 Monoplanes. I stand corrected on trying to describe the shock cord arrangement on the 2000 -- but it is closer to the "Cub" then it is to the '34 "Improved" Piet (!). For what it's worth, Doug Bryant (Wichita, KS) had built his Model "A" Piet with "Improved" landing gear & wire wheels. Mike C.

The shock cord attaches to the axle and center vee, unlike a Cub where the shock cord is entirely on the axle "spreader bar." I could come up with measurements for the Travel Air if anyone thought it would be useful, but I doubt it. Gene

    Subject: Re: Fus. Fuel tank idea
    I have always wondered why more homebuilders don't use these kind of fuel tanks. As some people on the newsgroup have mentioned before, if a NASCAR offical inspected the typical homebuild fuel system for safety he would laugh his butt off. WW is very sensitive to the issue of crash-worthy fuel systems after his burn injuries after a Piet crash. I know that few if any prebuilt tanks would fit in the center section but fitting one behind the firewall shouldn't be a problem.

    $2.40? Ha! Thats peanuts, I am in San Diego on a business trip and regular is already $2.99 before any increase. By the way had the afternoon off and visited the San Diego Aerospace Museam, it is excellent. They have the original wing rib jig used to make the Spirt of St. Louis wing down the road at Lindberg field and it used 1/2" x 1/4" cap strips just like the Piet except they are rotated 90 degrees so the entire rib is 1/4" thick.
