effective date of this Directive.
             This Amendment becomes effective on 2 August 2007.
Background:  A P-Pin PN201275602 connecting the lower end of the retraction actuator to the main fitting was found fractured upon removal during MLG overhaul.  Investigation concluded that the crack that caused fracture initiated from the centre grease hole of the P-Pin.  In this case, the centre grease hole was machined in an incorrect position, 90° from its normal position.  This failure and possibly resulting migration of the
             P-Pin may lead to an undamped extension of the landing gear.  Upon fully extending, the landing gear would be submitted to high loads possibly compromising its structural integrity.  This AD requires a visual inspection in order to detect and replace incorrectly manufactured P-Pins.

             This amendment changes the P/N of the pin referred to in the applicability section of this AD to P/N 201478612 from 201275612, which was referred to in the original telex AD issued by the DGAC.  There are no other changes.

             The original issue of this AD became effective 16 June 2004.
