The shop called it an "IRAN" actually.. I really wanted to make the point that when a piece of rotating machinery is damaged by hitting a fixed object a teardown should be considered mandatory. Ask Lycoming. I believe they have a new standard and even long grass is included. When mine was torn down a crack was found in the radius between the propellor flange and the journal. The crank had undergone NDT 300 hours earlier and it was felt that the crack had been missed as it was not a new crack. I hate to think what would have happened had that crack propagated to failure. The prop strike did me a favour in this case. In my case $17000 fixed the engine and $10,000 fixed the prop. I love this forum, a misery shared is a misery halved!!! Ian B.
