your comment about the arrow..I own a T tail arrow. I'm type rated in over 40 different aircraft, including helicopters and gliders. Putting the prop to full fine will only put 2 dents (as you put it) in the wings due to a heavy landing. I suggest to you that this would only happen when the aircraft is at a speed not sufficient to reduce the rate of descent (or flare) thereby indicating that the pilot was either trying to stretch out the glide profile to the point that the aircraft fell out of the sky or they just failed to flare althogether from a nose down dive! There is bugger all difference between fixed prop and CSU when it comes to engine failure....they all act like a break..and unless you have a feather function or want to pull the aircraft up into a vertical climb to stall the prop and stop rotation fully then it all comes down to the pilot. (I'm talking smaller aircraft).
I don't have any type ratings
But have flown most PA28's, including Arrow II and Arrow IV. The incident I refer to was in an Arrow II.......Anyway, my comment was to illustrate the dangers of being a robot and not thinking what you are doing but just doing them because the checklist says so.
In an Arrow there is a vast difference between RoD with the prop pulled back or pushed forward.......Granted if the engine has indeed failed the prop will probably be fully fine anyway, but in my example said chap just went through the checks, and was probablly going to *just* make it ok, but introducing the fully fine prop pushed them over the edge and they did indeed landed heavy and badly damaged the plane.
