EASA AIRWORTHINESS DIRECTIVE

AD No.: 2013-0178

Date: 07 August 2013

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 EU 748/2012, Part 21.A.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].

Design Approval Holder’s Name:

EUROCOPTER DEUTSCHLAND GmbH

Type/Model designation(s):

EC 135 and EC 635 helicopters

TCDS Number: EASA.R.009

Foreign AD: Not applicable

Supersedure: This AD supersedes EASA AD 2009-0207 dated 30 September 2009.

ATA 04 Time Limits / Maintenance Checks – Airworthiness Limitations –

Amendment

Manufacturer(s): Eurocopter Deutschland GmbH (ECD), Eurocopter España S.A., 

Eurocopter S.A.

Applicability: EC 135 P1(CDS), EC 135 P1(CPDS), EC 135 P2(CPDS), EC 135 P2+, 

EC 135 T1(CDS), EC 135 T1(CPDS), EC 135 T2(CPDS), EC 135 T2+, 

EC 635 T1(CPDS), EC 635 P2+ and EC 635 T2+ helicopters, all serial 

numbers.

Reason: The airworthiness limitations for the EC 135 and EC 635 type design are 

currently defined and published in ECD Master Servicing Manual (MSM) EC135 

Chapter 04 – Airworthiness Limitations Section (ALS) documents.

ECD recently revised the EC 135 ALS document, and this new ALS revision

has been approved by EASA.

Revision 15 and Temporary Revision 16a introduce new airworthiness 

limitations. Failure to comply with the instructions contained in those documents

could result in an unsafe condition.

For the reasons described above, this AD retains the requirements of EASA 

AD 2009-0207, which is superseded, and requires the implementation of the 

new airworthiness limitations as specified in ECD MSM EC 135 Chapter 04

Revision 15 and Temporary Revision 16a.

Effective Date: 21 August 2013
