Good evening. As for the norms for the propeller, then in FAR-35 (paragraph 35.35. In particular) it is said that double centrifugal loads must be applied within one hour. Obviously, these will be the maximum revolutions at which vibrations of any nature should be detected, including dynamic imbalance. Matiychyk.
