### 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 - Insp ection

Manufacturer(s): Airbus (formerly Airbus Industrie)

Applicability: Airbus A380 aeroplanes, -841, -842 a nd -861 models, MSN (Manufacturer Serial Number) 15, 17, 19, 20, 21 and 22.

Reason During inspection in production and on in-se rvice aircraft, a number of OverHeat Detection System (OHDS) installation non-c onformities have been identified along the bleed air ducting. Some installation issues which may lead to a degrad ed leak detection capability have been reported. In case of hot air l eakage, the potential degradation of the OHDS would not allow preventing damages to structure or components, and therefore could lead to an unsaf e condition. To ensure that in-service aeroplanes are free of su ch non-conformities, EASA AD 2009-0066 required an inspection of the OHD S installation along the bleed air ducting and, in case of finding s, to bring back the installation into the compliant configuration. That AD required a complete inspection for some MSN, and a partial inspection f or 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, requir es to perform :

• an additional inspection on MSN 15, 20 and 22 to r ender it complete, andEASA AD No.: 2009-0265

EASA Form 110 Page 2/2 • a complete inspection on additional MSN.
