zanthrus, you can always be relied upon to make some stupid post, whatever the thread. Now shut YOUR cake hole. No one knows exactly what happened, and we await the ATSB report, but in the mean time we are free to discuss.
what dimensions did you use for the roof cladding
I used 700mm which is quoted as the coverage for a single sheet. I assumed that would have meant 350mm from ridge to ridge.
So how do we account for so much (apparent) yaw to the left?
From the manual.
CAUTION
With one-engine either at idle or inoperative, flaps UP and propeller windmilling, VMCA may be as high as 108 KIAS.
Note the last groundspeed, and we can assume the airspeed, given the wind was 23005, to be the same, was 108 knots. Recommendation from the good book for practice Vmca demonstration is a minimum of 5,000 feet, clearly not something to be trifled with.
Low side governor failure, P3 air leakage?
