AD No.: 2012-0152

Date: 13 August 2012

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 EC 1702/2003, Part 21A.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

ATA 56 Windows – Jettisonable Emergency Exit Window Panels –

Inspection

Manufacturer(s): Eurocopter (formerly EUROCOPTER France)

Applicability: AS 332 C, AS 332 C1, AS 332 L, AS 332 L1, AS 332 L2 and EC 225 LP 

helicopters, all serial numbers, delivered before 20 July 2012 and on which the 

window jettison test has never been performed.

Reason: When performing jettison tests during 2 years for maintenance check, 

difficulties has been encountered in jettisoning the window panel.

The investigations have shown on several windows that there was sealant 

between the extrusion and the window.

This condition, if not detected and corrected, could prevent the jettisoning of a 

window, possibly affecting the evacuation of passengers in the event of an 

emergency situation.

For the reasons described above, this AD requires an inspection of each 

jettisonable window panel of the emergency exits and, depending on findings,

accomplishment of the applicable corrective actions.

Effective Date: 27 August 2012
