2007.
Background:  The manufacturer received a report of failure and a report of cracking of the sliding door rear roller support pin.  Investigation revealed that the cracks started from a spring pin bore and grew due to fatigue.  Metallurgical analysis revealed heat treatment non-conformity of the pin material.

             Amendment 1 was prompted by reports of cracking and failure of the roller support shaft rear attaching fitting.

             Amendment 2 converted the Requirement document to an Alert Service Bulletin with the same reference number, and mandated modification action that cancels the inspection requirements of this Directive.

             Amendment 3 extended the compliance time for Requirements 2, 3, and 4.

             Amendment 4 is issued in response to a new EASA AD, which requires repetitive inspections until replacement of current parts with improved parts and also prohibits installation of another roller support fitting part number 350A25-1270-22 on any
             AS 350 helicopter.
