(a)     reserved

(b)     Engine power and propeller shaft rotational speed may not exceed the limits for which the propeller is certificated. (See CS-P 50.)

(c)      Each component of the propeller blade pitch control system must meet the requirements of CS-P 420.

(d)     Design precautions must be taken to minimise the hazards to the aeroplane in the event a propeller blade fails or is released by a hub failure. The hazards which must be considered include damage to structure and critical systems due to impact of a failed or released blade and the unbalance created by such failure or release. (See AMC 25.905(d).)
