Preservation propeller and storage

[Check Team FR]

Hi, 

when should we preserve a propeller on an airplane?

After how many days of aircraft immobilization, do you start preserving a propeller?

Preservation is planned for checks but is it necessary for immobilization of less than 15 days or 1 month or 2 months?

Hello, i have a another problem, ASB 54H60-61-A157 say a propeller is adequately preserved if the propeller is rotated once in 2 month.

But the preservation in P5059 is it necessary for have a adequately preserved propeller or just a rotation ?

And last question, a aircraft immobilized for check may be considered like an active aircraft (term in ASB) ?

Thanks for your responce.
