I am aware of TC SB 96-11A and I have decided not to purchase 3 planes that had strikes and the engines were not torn down. I am also aware of a company that sells planes after a prop strike that clocks the prop and dye tests the parts of the engine that they can see with a scope. I am not trying to make this about who does what. The SB says, " This damage can result in catastrophic engine failure.". The question I have is this is anyone aware of a case where the result of a prop strike and non tear down procedure was used to return the aircraft resulted in this failure? Or is this the type of statement that was generated due to liability concerns.
Secondly has anyone had their engine torn down and replaced in service without any changes to the engine caused by the Prop Strike or is some hidden damage discovered and parts replaced?
