EASA AIRWORTHINESS DIRECTIVE

AD No.: 2013-0213

Date: 13 September 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:

AUSTRO ENGINE GmbH

Type/Model designation(s):

E4 engines

TCDS Number: EASA.E.200

Foreign AD: Not applicable

Supersedure: This AD supersedes EASA AD 2013-0025R1 dated 30 April 2013.

ATA 72 Engine – Waste Gate Controller – Replacement

Manufacturer(s): Austro Engine GmbH

Applicability: Model E4 engines, all serial numbers.

These engines are known to be installed on, but not limited to, Diamond Aircraft 

Industries DA 40 NG and DA 42 NG aeroplanes.

Reason: Several power loss events have been reported on Austro E4 engines, due to 

fracture of the waste gate controller lever. 

This condition, if not corrected, could lead to further cases of power loss 

events, possibly resulting in forced landing, damage to the aeroplane and injury 

to occupants.

To address this potential unsafe condition, Austro Engine introduced a waste 

gate controller of improved design, Part Number (P/N) E4A-41-120-000 revision 

(Rev.) 070, or higher.

Consequently, EASA issued AD 2013-0025 (later revised) to require 

replacement of all previous revisions of waste gate controllers having P/N E4A41-120-000 and P/N E4B-41-120-000, with improved design units having P/N 

E4A-41-120-000 Rev.070, or E4C-41-120-000 Rev. 000, units or higher.

Since AD 2013-0025R1 was issued, based on further in-service failure 

occurrences, Austro Engine GmbH established that waste gate controllers P/N 

E4A-41-120-000 Rev. 060 and P/N E4C-41-120-000 Rev. 010 are no longer 

eligible for installation, and Austro Engine Mandatory Service Bulletin (MSB) 

MSB-E4-007 was revised accordingly.

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