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.

Perry, now that you describe it, seems that I did read something about an
incident like that somewhere. Yes, I noticed the hole in the NTSB last
paragraph.
