            This Amendment becomes effective on 25 December 2003.

            Background: The manufacturer has reported several blade separations resulting from cracks in the hubs, blades or blade clamps of this propeller series. Due to difficulty of detecting cracks the manufacturer has reduced the TBO of certain propeller models fitted to piston engine aircraft and introduced additional inspection procedures.

            Amendment 1 revised the compliance draw down requirements to include reference to the 10-year calendar overhaul period for Hartzell propellers as specified in AD/PROP/1 Amdt 1.

            Amendment 2 provides a terminating action. Modification of the propeller to the "MV" series will remove the propeller from the applicability of this Directive.

            Amendment 1 of this Directive became effective 1 January 1998.

            The original issue of this Airworthiness Directive became effective on 1 January 1998.
