We are superseding an existing airworthiness directive (AD) for the products listed above. This AD results from mandatory continuing airworthiness information (MCAI) issued by an aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe condition as:
Unless already done, do the following actions:
(1) For all affected Models PC-6/B2-H2 and PC-6/B2-H4; Before further flight after March 8, 2011 (the effective date of this AD), incorporate the maintenance requirements as specified in Pilatus PC-6 AMM Chapter 04-00-00, Revision 12, Document Number 01975, dated May 14, 2010, into your FAA-accepted maintenance program.
(2) For all affected PC-6 models other than the Models PC-6/B2-H2 and PC-6/B2-H4; Before further flight after March 8, 2011 (the effective date of this AD), incorporate the maintenance requirements as specified in Pilatus PC-6 AMM ALS Document Number 02334, Revision 1, dated May 14, 2010, into your FAA-accepted maintenance program.
