I am not so sure. The annual would still need to be performed on the found prop after the fact. How would that work? Plus, there would be other items that could not be performed as part of the annual, such as the engine runs and ops checks, with no prop installed. As noted above:
The aircraft is the sum of all of it's parts - engine, prop, left wing, pilot seat, right elevator, nose wheel, etc, etc. The annual is supposed to be a "snapshot" in time that attests that it was airworthy on this date. An aircraft can't be airworthy if it is missing a prop (other than a jet
) or the right elevator or some other part that is legally required in order to make the aircraft whole (meet it's type design).
What if the prop is attached, but is found to have a few nicks in the leading edge? Would that change anything?
As far as performing maintenance over a period of time and using that as a reason to justify signing off on an annual at a later date, to appease an owner ... sorry, not this guy. I am not saying that I don't bend a bit here and there, but I feel it is a slippery slope and once you start going down that path, it can become difficult to stop. My licence and livelihood are intertwined, but I also need to sleep at night.
I find it funny how an owner who flys maybe 10 hours a year will need his aircraft right at the moment it is due for an inspection, like somehow it came out of no where! And of course the "mission" is life and death!
