                                                                                                                                                                                                                                                                 Table 2 - Compliance Schedule
                                                                                                                                                                                                                                                                 If on the Effective Date of this Directive, the Propeller Blade:                                                                                                                                                                                    Then Inspect the Propeller Blade:
 Has more than 2,400 operating hours TSN, time-since-last inspection (TSLI) or time-since-overhaul (TSO) and has been inspected using AD/PMC/52 (FAA AD 2008-08-01) or McCauley Propellers ASB255, dated 8 January 2007, within the past 2,400 operating hours.   Upon reaching 2,500 operating hours TSLI.  (For the purpose of this Directive, TSLI refers only to inspections performed using AD/PMC/52 or ASB255.)
 Has more than 2,400 operating hours TSN, TSLI or TSO and has not been inspected using AD/PMC/52 or ASB255 within the past 2,400 operating hours.                                                                                                                 Within the next 100 operating hours time-in-service.

              Has 2,400 or fewer operating hours TSN, TSLI or TSO.                                                                                                                                                                                                                                                                                                                                                                                                                                                     Upon reaching 2,500 operating hours TSN, TSLI or TSO.
             For Requirements 7, 8 and 9 - Before further flight after the Requirement 6 inspection(s).
             For Requirement 10 - As of the effective date of this Directive.
             For Requirement 11 - Within ten calendar days of completing the inspection(s).
             This Airworthiness Directive becomes effective on 27 October 2009.
Background:  This Directive supersedes AD/PMC/52 which will be cancelled.  That Directive required initial and repetitive fluorescent penetrant inspections together with eddy current inspections of propeller blades for cracks.  That Directive required the removal from service of propeller blades if any crack indications were found, the Directive also mandated a life limit for the blades.
             This Directive requires the same inspections, adds a visual inspection and mandates a new propeller blade life limit.  This Directive also requires removing propeller blades with more than 10,000 operating hours TSN.  This Directive also requires removal from service of all the propeller blades and the propeller hub if one or more propeller blades have been found cracked on a propeller assembly.  Additionally, this Directive requires removing from service all C-5963 split retainers.
             This Directive results from the United States Federal Aviation Administration receiving eight reports of propeller blades found cracked since May 2006.  The Directive is issued to detect cracks in the propeller blade that could cause failure and separation of the propeller blade and loss of control of the aeroplane.
