EASA AIRWORTHINESS DIRECTIVE 

AD No.: 2014-0080 

Date: 27 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: 

AIRBUS HELICOPTERS 

Type/Model designation(s): 

AS 332 L2 helicopters 

TCDS Number: EASA.R.002 

Foreign AD: Not applicable 

Supersedure: None 

ATA 67 Rotor Flight Controls – Yaw Control Damper Support – Inspection / 

Replacement 

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

Applicability: AS 332 L2 helicopters, all serial numbers, equipped with yaw control damper 

support Part Number (P/N) P/N 332A25-1334-00. 

Reason: Several cases of cracks of the two front attachment points of the yaw control 

damper support were reported. The subsequent investigations determined that 

pilot actions on the yaw pedals could generate detrimental loading conditions 

on the support attachment points and initiate cracks. 

This condition, if not detected and corrected, could lead to structural failure of 

the yaw control damper support, resulting in detachment of the damper unit, 

possibly blocking of the yaw flight control channel and consequent reduced 

control of the helicopter. 

To address this potential unsafe condition, Airbus Helicopters issued Alert 

Service Bulletin (ASB) No. AS332-05.00.98 to provide inspection and 

replacement instructions. 

For the reasons described above, this AD requires repetitive inspections of the 

yaw control damper support and, depending on findings, replacement.
