According to NTSB 830.5 (a) the only accidents with "substantial
damage" are reportable. NTSB 830.2 defines "substantial damage" and
specifically states "Engine failure or damage limited to an engine if only
one engine fails or is damaged, bent fairings or cowling, dented skin,
small punctured holes in the skin or fabric, ground damage to rotor or
propellor blades, and damage to landing gear, wheels, tires, brakes, or
wingtips are not considered "substantial damage" for the purpose of this
part".

Yep...when I had my engine failure and resultant emergency landing...despite
hosing the engine (total loss) and some minor gear and prop damage, there
was no report. Not only that, when the airport manager called the FAA,
they were so busy dealing with a fatal ultralight crash in the next county over
that when they heard there was no injuries and no "substantial" damage they
said forget it. It never showed up even in the FAA accident reports.
