EASA AIRWORTHINESS DIRECTIVE

AD No.: 2014-0056

Date: 07 March 2014

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:

ATR-GIE AVIONS DE TRANSPORT 

RÉGIONAL

Type/Model designation(s):

ATR 42 and ATR 72 aeroplanes

TCDS Number: EASA.A.084

Foreign AD: Not applicable 

Supersedure: None

ATA 92 Electrical Routing – Electronic Rack 120VU Shelf / Electrical 

Harness – Inspection / Modification

Manufacturer(s): ATR-GIE Avions de Transport Régional (formerly Aerospatiale – Aeritalia, 

Aerospatiale – Alenia, Aerospatiale ATR – ALENIA, EADS ATR – Alenia).

Applicability: ATR 42-500 aeroplane model, from Manufacturer Serial Number (MSN) 669 to 

1005 inclusive, and 

ATR 72-212A aeroplane model, MSN 773, MSN 774, from MSN 776 to 1094 

inclusive, from MSN 1096 to 1099 inclusive and MSN 1101.

Reason: During inspection of an aeroplane on the production line, interference was 

detected between electrical harnesses (2M-2S-6M) and a bonding lead, located 

in zone 214, positioned above and forward of the 120VU shelf. Subsequent 

investigation revealed that the interference was a result of an incorrect 

installation of the affected bonding lead.

This condition, if not detected and corrected, could lead to arcing and chafing, 

possibly resulting in an uncontrolled fire.

To address this potential unsafe condition, ATR issued Service Bulletin (SB)

ATR42-92-0025 and SB ATR72-92-1034, as applicable to aeroplane model, to 

provide inspection instructions.

For the reasons described above, this AD requires a one-time inspection of the 

electrical harness 2M-2S-6M in zone 214 and, depending on findings, 

accomplishment of corrective action(s).
