As Mike said, it depends on who did the TDI, and whether they followed the letter of the AD/Lycoming service instructions completely. There are parts that automatically get replaced with new during a prop strike TDI - crankshaft gear and bolt, roller lifters if you have them, both mags - to name a couple items. The TDI instruction is fairly detailed. You should read the tear down report to find out what they did and compare it to the requirements in the prop strike service instructions. Done properly, you shouldn’t have anything to worry about, although just having a prop strike does affect what somebody is willing to pay for the airplane that can’t say “NDH”. I have personal experience with this that I’m not going to waste time explaining, but be sure the correct TDI procedures were followed by a reputable shop. If the owner says that this isn’t required because it’s an EAB, he is right, and you shouldn’t let the door hit you in the backside on your way out of there. In addition to my experiences, we are dealing with a new RV8 owner at our airport who purchased her airplane after a prop strike that wasn’t handled correctly because it was a home built, and now she is having issues.
