EASA AIRWORTHINESS DIRECTIVE

AD No.: 2013-0093

Date: 15 April 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

Type/Model designation(s):

TCDS Number: DGAC France No.189 and EASA.R.008

Foreign AD: Not applicable

Supersedure: None

ATA 52 Doors – Sliding Door Star Support – Modification

Manufacturer(s): Eurocopter (formerly Eurocopter-France)

Applicability: EC 120 B helicopters, all Serial Numbers (S/N) below 1368, equipped with 

sliding door P/N C526A2370101, and

EC 130 B4 helicopters, all S/N, equipped with sliding door P/N C526S1101051, 

except those helicopters that have incorporated Eurocopter modification (MOD)

07 3796 (reinforcement of the sliding door star support attachment) in 

production, or have incorporated Eurocopter MOD 07 2921 (industrialized 

sliding door) in production.

Reason: A case has been reported where, after landing, the passengers of an 

Eurocopter helicopter could not open the sliding door from inside. The 

passengers had to leave the helicopter through the pilot door.

The investigation revealed a sliding door star axle support failure.

This condition, if not corrected, could delay the evacuation from the helicopter

in case of emergency, possibly resulting in injury to the occupants.

For the reason described above, this AD requires modification of the sliding 

door star support.

Effective Date: 29 April 2013
