disassembly, thereafter at intervals specified in the Compliance section of Hartzell Propeller Inc. SB No. HC-SB-61-287, Revision 4 or later FAA approved revision.
                This Amendment becomes effective on 24 August 2010.
Background:     This AD results from reports of excessive propeller vibration and of damaged or broken propeller blade thrust bearings found during routine and investigative propeller disassembly.  The issuing of this AD is to prevent propeller blade separation, damage to the aeroplane, and possible loss of aeroplane control.

                Amendment 1 increases the repetitive inspection/rework interval to reflect the latest revision of the manufacturers service bulletin which is approved as an AMOC to the original compliance interval as detailed in FAA AD 2007-08-02.

                Amendment 2 harmonizes the repetitive inspection/rework interval with the latest revision of the manufacturers service bulletin which is approved as an AMOC with FAA AD 2007-08-02.
