a serviceable PCU.

                   5. Remove the PCU from service and perform a Major Periodic Inspection (overhaul), in accordance with paragraphs 2.B. and 2.C. of Hartzell SB
                   HD-SB-61-025, Revision 1 or later FAA approved revisions.

                Optional Terminating Action

                Replacement with a serviceable PCU is terminating action for the repetitive inspections specified in requirement 3 of this AD. For the purpose of this AD, a serviceable PCU is one that is not listed in Table 1 of this AD, or is one listed in Table 1 of this AD that has undergone a Major Periodic Inspection (overhaul) after
                17 November 2000, in accordance with paragraphs 2.B. and 2.C. of Hartzell SB
                HD-SB-61-025, Revision 1 or later FAA approved revisions.

                Note 2:  FAA AD 2003-04-22 Amdt 39-13071 refers.
Compliance:           1 and 2. At the next "2A" maintenance check, but no later than 600 hours time-in-service from the effective date of this AD.

                      3 and 4. At each successive "4A" maintenance check, but not to exceed 1,200 hours time-in-service.

                      5. Once the limiting time-since-overhaul or time-since-new specified in Hartzell SB HD-SB-61-025, Revision 1 or later FAA approved revision is reached.
                This Airworthiness Directive becomes effective on 19 January 2006.

Background:  This AD is prompted by a review by Hartzell Propeller Inc. of the model D-1199-2 PCU overhaul procedures, that revealed several dimensional checks and a non-destructive evaluation were not performed on certain serial number PCU's during a Major Periodic Inspection (overhaul).  The overhaul procedures are required to comply with the Airworthiness Limitation PCU Major Periodic Inspection (overhaul) directive.  The actions specified by this AD are intended to prevent below-limit flight idle propeller blade angles that, if not corrected, could result in degraded aircraft performance and control.
