Props and the N reg
Some clarification needed here.
Can anyone confirm whether manufacturers recommended overhaul periods for props (either 5 or 6 years depending on make) are mandatory?
I thought I had read somewhere that they can be run 'on condition'.
This is not to debate the sensibility of running 'on condition' but the legality

Surely the manual would contain the manufacturers recommendations?, but that isnt necessarily the legal requirement? That would be somewhere if FAR part 91 or part 43. trouble is, I cant find it

Which brings up an interesting point for aeroplanes on the UK register.
I understand that you can either opt for a Notice 75 schedule or operate to the manufacturers schedule, then overhaul.
I once looked at a Zlin that hadn't had a Notice 75 for 5 years, it's C of A had been renewed because it was operating to the manufacturers overhaul schedule.
Comments welcome because I detest the thought of doing Notice 75's on a perfectly serviceable prop.

It may...depend on how the a/c is used. For instance in the US, engine TBO is mandatory for commercial use, but optional for private only use.
What do you mean by N reg btw?

According to the FAA it is mandatory to comply with the maintenance manual.
BUT as a rule prop and engine overhaul lives are stated in a service bullitins which are not considered mandatory by the FAA.
Therefore if you are operating on the N-Reg under Part 91 (private) you do not have to carry out prop or engine overhauls if you dont want to.

I thought Notice 75 was extinct now, and G aircraft fly to the manufacturer's recommended service intervals?
We had ours done at 5 years after the Notice 75 (and needed a new prop).
