I am aware of AD 2004-10-14c. As I recall, before that, one would often "dial in" the crankshaft flange and bolt another prop on. Indeed I did that once in West Texas many decades ago.
So - question: part 91, is it still legal to do that on Continentals? Yes, I have seen broken cranks on small Continentals, most likely due to a prop strike in the distant past, but just asking about legalities.
Trigger for the question - low speed nose-over on a 180. Very little damage other than to prop blades, and he is considering "dial it in" and a new set of blades. All I could say is "that's what we did in the 1960s."
