### ATA 05 Time Limits / Maintenance Checks – Airworthiness Li mitations

Section – Amendment / Implementation

Manufacturer(s): Pilatus Aircraft Ltd. and Fairchil d Republic Company (formerly known as Fairchild Industries, Fairchild Heli Porter and Fai rchild-Hiller Corporation).

Applicability: All model PC-6 series aeroplanes, al l Manufacturer Serial Numbers (MSNs) and all PC-6 series aeroplanes, manufactured by Fairchild in the United States of America, all MSNs.
Reason: The current Aircraft Maintenance Manual (AM M) of PC-6 B2-H2 and B2- H4 models does not include a Chapter 04 in the Airw orthiness Limitations Section (ALS). For PC-6 models other than B2-H2 and B2-H4, no ALS at all is included in the AMM. With the latest Revision 12 of the AMM, a new Chapt er 04 has been introduced in the AMM for PC-6 B2-H2 and B2-H4 mode ls. For PC-6 models other than B2-H2 and B2-H4, a new A LS document has been implemented as well. These documents include the Mandatory Continuing Ai rworthiness Information (MCAI) which are maintenance requiremen ts and/or airworthiness limitations developed by Pilatus Airc raft Ltd and approved by EASA. Failure to comply with these MCAI constitutes an unsafe condition. For the reasons described above, this AD requires t he implementation and the compliance with these new maintenance requireme nts and/or airworthiness limitations documents.EASA AD No : 2010-0176
