I’m sure you are a fine IA and I have no doubt that you do your due diligence in researching AD compliance. However, that isn’t really what I was talking about.
I was addressing your earlier statement:
“the only logs required are from the latest annual and any STC and 337's that affect the airworthiness of the aircraft.”
Which isn’t entirely accurate with respect to 91.417. The most recent annual entry in a logbook does not, by itself, fully meet the AD documentation requirements of 91.417. As an owner, in order to meet the requirement of retaining documentation of method of compliance of ADs I would need to retain any logs with those entries.
If you are involved in an incident/accident related to the failure of a part that had been subject to an AD, the FAA will want to see your log books with full documentation of compliance with that AD. If you can’t produce those logs then you are not in compliance and you risk FAA sanctions. Presenting just the most recent annual inspection entry will not be sufficient.
