this AD.  If you do not overhaul the propeller, the TSO does not change.

                (2) Unacceptable wear is wear or damage that can penetrate the shot peen compressive layer.

             Note:  FAA AD 2006-24-07 Amdt 39-14836 dated 21 November 2006 refers.
Compliance:     1. Within 30 days after the effective date of this AD.

                2. If the propeller was involved in a ground strike, within 10 flight hours (FH) time-in-service (TIS) after the effective date of this AD, or 2 years after the effective date of this AD, whichever is earlier.

                For all propellers listed by SN in Table 1 of this AD, not involved in a ground strike, using the compliance schedule detailed in Table 2 of this AD.

                Table 2. - Compliance Schedule

              If the time-since-overhaul (TSO) for the propeller on the effective date of this AD is …   Then perform the requirements of paragraph (j) or paragraph (k) of this AD within …
                (1) 1,500 FH TSO or more.                                                                200 FH TIS after the effective date of this AD, but do not exceed 2 years after the effective date of this AD.
                (2) More than 1,000 FH TSO, but fewer than 1,500 FH TIS.                                 350 FH TIS after the effective date of this AD, but do not exceed 2 years after the effective date of this AD.
                (3) 1,000 FH TSO or fewer.                                                               500 FH TIS after the effective date of this AD, but do not exceed 2 years after the effective date of this AD.

             This Airworthiness Directive becomes effective on 7 June 2007.
Background:  This AD pertains to certain Hartzell Propeller Inc. HC, BHC, and PHC series propellers serviced by Oxford Aviation Services Limited, doing business as CSE Aviation, in the United Kingdom between September 1998 and October 2003.  This AD requires inspecting the propeller blades and other critical propeller parts for wear and mechanical damage.  This AD results from findings that CSE Aviation failed to perform some specific inspections and repairs.  The issuing of this AD is to detect unsafe conditions that could result in a propeller blade separating from the hub and loss of control of the aeroplane.
