EASA AIRWORTHINESS DIRECTIVE

AD No.: 2015-0020

Date: 11 February 2015

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 1321/2014 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:

AIRBUS HELICOPTERS

Type/Model designation(s):

EC 120 B and EC 130 B4 Helicopters

TCDS Number: EASA.R.508 and EASA.R.008

Foreign AD: Not applicable

Supersedure: This AD supersedes EASA AD 2013-0093 dated 15 April 2013, including the 

Correction dated 17 April 2013.

ATA 52 Doors – Sliding Door Star Support – Modification

Manufacturer(s): Airbus Helicopters (formerly Eurocopter, Eurocopter-France)

Applicability: EC 120 B helicopters, all Serial Numbers (S/N), equipped with sliding door Part 

Number (P/N) C526A2370101, except those helicopters that have incorporated 

modification (MOD) A00565 (reinforcement of the sliding door star support 

attachment), and

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

except those helicopters that have incorporated MOD 07 3796 (reinforcement of 

the sliding door star support attachment), or have incorporated Eurocopter MOD 

07 2921 (industrialized sliding door).

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.

To address this potential unsafe condition, Eurocopter published EC120 Alert 

Service Bulletin (ASB) No. 52A014 and EC130 ASB No.52A009 (both Revision 1) 

to provide modification instructions.

Consequently, EASA issued AD 2013-0093 to require modification of the sliding 

door star support.

Since that AD was issued Airbus Helicopters issued Revision 2 of EC120 ASB No

52A014 to revise and correct the applicability, to extend it to all s/n helicopters 

with the affected P/N door, except those in a specific MOD configuration.

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

2013-0093, which is superseded, and changes the applicability for EC 120 B

helicopters.
