[FlyRotary] Re: [FlyRotary]2002 crash of Taylor Coot w/13b
  Yes I knew the pilot of that coot very well and the engine installation was a compleat abortion and the coot was tail heavy and I knew it by just looking at it despite what his calculation were.
 On the first taxi run that he got the nose wheel up it jumped in the air and with full stick forward he could not get the nose down so it stalled about 10 ft off the ground on landing it folded up two of the gear.
 He then  repaired the plane and wanted me to fly it for him and I said no way its tail heavy and he still refused to believe me.
 He then went out and tried to fly it and right after liftoff the engine caught fire and quit, then the coot stalled and pancaked in and went up in a ball of fire.
 What I suspect the fire was from was a cheep ass piece of crap oil cooled that he got at a local auto parts store in which I told him would not holed up to the high oil pressure and volume out the Mazda.
 Another thing was that the oil cooler was mounted in the cowl ahead of the cheep exhaust system made from standard exhaust pipe and muffler from Napa which  I told he would not hole up to the Mazda temps.
  This is really just the tip of the iceberg as I could go on and on, just say this plane was an accident looking for a place to happen.

Tom, as best I recall, Ken Welter reported that the Taylor Coot had an "aft
cg problem" before it flew and Ken had warned the pilot that the aft cg
could produce an unrecoverable stall condition.  I believe he was also
warned that if the engine ever quite with that rear CG - an unrecoverable
stall would immediately happen.  So with that initial aft CG condition and
the subsequent engine stoppage and resulting rearward drag caused by a
stopped propeller   precluded any recovery from the induced stall.  The
cause of the engine stoppage was reportedly due to an oil cooler (not stock
Mazda) that burst which led to a loss of the oil and the engine eventually
seizing - from which there was no recovery.

Unfortunately the NTSB knew nothing about rotary engines, so they went to a
local Mazda dealer (who probably did not know much more) and because the oil
injection lines had been removed from the engine (and the side housings were
reportedly "blued" from the heat of no lubrication) the NTSB quickly jumped
on that as  the cause of failure.  Of course no injected oil might cause
your apex and possibly your corner seals to wear faster than normal but
would not cause the engine to seize.  So the NTSB missed it on this one.

Unfortunately, here was an accident that did not have to happen.  But, when
a person disregards well intended warnings - there is little anyone can do.
