crack indication involving propellers from MU-2B-60 aircraft. Hartzell issued ASB A182 specifically for the MU-2B-60 aircraft. Due to the similarity of the MU-2 propeller assembly, Hartzell has extended the inspection to include the propellers fitted to the MU-2B-26A, -36A and -40 series aircraft.

               Amendment 1 added the MU-2B-60 to the AD requirements, provided terminating action for the repetitive 600 hourly hub inspection and introduced the revised blade width and thickness limits to ensure REACTIONLESS MODE vibration does not affect the propeller airworthiness.

               Amendment 2 has been raised to include the part numbers of the hub units that are exempted from the 600 hour repetitive inspection.
