EASA AIRWORTHINESS DIRECTIVE 

AD No.: 2010-0176 

Date: 20 August 2010 

Note: This Airworthiness Directive (AD) is issued by EASA, acting in accordance with 

Regulation (EC) No 216/2008 on behalf of the European Community, its Member States 

and of the European third countries that participate in the activities of EASA under Article 

66 of that Regulation. 

This AD is issued in accordance with EC 1702/2003, Part 21A.3B. In accordance with EC 2042/2003 Annex I, Part M.A.301, the 

continuing airworthiness of an aircraft shall be ensured by accomplishing any applicable ADs. Consequently, no person may 

operate an aircraft to which an AD applies, except in accordance with the requirements of that AD, unless otherwise specified by 

the Agency [EC 2042/2003 Annex I, Part M.A.303] or agreed with the Authority of the State of Registry [EC 216/2008, Article 

14(4) exemption]. 

Type Approval Holder’s Name : 

Pilatus Aircraft Ltd.

Type/Model designation(s) : 

PC-6 aeroplanes 

TCDS Number: Switzerland No. F 56-10 

Foreign AD: Not applicable 

Supersedure: None 

ATA 05 Time Limits / Maintenance Checks – Airworthiness Limitations 

Section – Amendment / Implementation 

Manufacturer(s): Pilatus Aircraft Ltd. and Fairchild Republic Company (formerly known as 

Fairchild Industries, Fairchild Heli Porter and Fairchild-Hiller Corporation). 

Applicability: All model PC-6 series aeroplanes, all 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 (AMM) of PC-6 B2-H2 and B2-

H4 models does not include a Chapter 04 in the Airworthiness 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 Chapter 04 has been 

introduced in the AMM for PC-6 B2-H2 and B2-H4 models. 

For PC-6 models other than B2-H2 and B2-H4, a new ALS document has 

been implemented as well. 

These documents include the Mandatory Continuing Airworthiness 

Information (MCAI) which are maintenance requirements and/or 

airworthiness limitations developed by Pilatus Aircraft Ltd and approved by 

EASA. Failure to comply with these MCAI constitutes an unsafe condition. 

For the reasons described above, this AD requires the implementation and 

the compliance with these new maintenance requirements and/or 

airworthiness limitations documents.
