EASA AIRWORTHINESS DIRECTIVE 

AD No.: 2009-0265 

Date: 16 December 2009 

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 Airworthiness Directive applies, except in accordance with the requirements of that 

Airworthiness Directive 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]. 

Type Approval Holder’s Name : 

AIRBUS 

Type/Model designation(s) : 

A380 aeroplanes 

TCDS Number : EASA.A.110 

Foreign AD : Not applicable 

Supersedure : This AD supersedes EASA AD 2009-0066 dated 19 march 2009 

ATA 36 Pneumatic – Overheat Detection System - Inspection 

Manufacturer(s): Airbus (formerly Airbus Industrie)

Applicability: Airbus A380 aeroplanes, -841, -842 and -861 models, MSN (Manufacturer 

Serial Number) 15, 17, 19, 20, 21 and 22. 

Reason During inspection in production and on in-service aircraft, a number of 

OverHeat Detection System (OHDS) installation non-conformities have 

been identified along the bleed air ducting. 

Some installation issues which may lead to a degraded leak detection 

capability have been reported. In case of hot air leakage, the potential 

degradation of the OHDS would not allow preventing damages to structure 

or components, and therefore could lead to an unsafe condition. 

To ensure that in-service aeroplanes are free of such non-conformities, 

EASA AD 2009-0066 required an inspection of the OHDS installation 

along the bleed air ducting and, in case of findings, to bring back the 

installation into the compliant configuration. That AD required a complete 

inspection for some MSN, and a partial inspection for MSN 15, 20 and 22. 

This partial inspection has now been assessed to be insufficient to cover 

the unsafe condition. 

This AD, which supersedes EASA AD 2009-0066, requires to perform : 

• an additional inspection on MSN 15, 20 and 22 to render it 

complete, and 
EASA AD No.: 2009-0265 

EASA Form 110 Page 2/2 

• a complete inspection on additional MSN. 

Effective Date: 30 December 2009 

Required action(s) 

and Compliance 

Time(s): 

Required as indicated, unless accomplished previously : 

(1) Within 3 months from the effective date of this AD, in accordance 

with the instructions of Airbus Service Bulletin (SB) A380-36-8009, 

perform a one time Detailed Visual Inspection in order to ensure the 

correct installation of the OHDS Sensing Elements and Insulation 

Muffs and, in case of findings, bring back the installation into the 

compliant configuration. 

(2) Within 30 days after the accomplishment of the inspection as per 

paragraph (1) of this AD, report the inspection results, whatever they 

are, to Airbus.
