I heard a rumor that one of the previous owners of a KR I bought had a prop strike. The prop looked like it was new, but the guy denied the prop strike. I checked the hub for runout and it was fine. I pulled the crank anyway and had it magnafluxed and the shop told me that they found the biggest crack through the keyway that they had ever seen. Glad they found it and not me.

I called Revmaster about the need for a rebuild. Joe said try to start it first. Sorry gang, but I am on a soap box this morning. Larry I normally agree with most of what you say, but read what you said again.. To me that is totally irresponsible to post to a bunch of builder would be pilots who might not know any better. Standard procedure in certified engines is a complete teardown after ANY prop strike. All the testing on the ground you want to make will not show you the cracks, nor will it prove it is not cracked. I knwo of three netters on this list alone that have had crankshafts crack after they were told no, but later found out in fact their planes sufferred a prop strike. Do what you want to but PLEASE don't tell people that it is acceptable or correct to fly an engine after a prop strike, without having the crank removed and magnafluxed. The only possible exception would be to ferry it to a location to get it torn down...
