AIRBUS INDUSTRIE
A310 Aircraft
Wing to fuselage upper fairings (ATA 53)
APPLICABILITY:
AIRBUS INDUSTRIE A310 aircraft :
A310-300 aircraft : all certified models and all serial numbers on which AIRBUS INDUSTRIE modification No 11758 has not been embodied, and
A310-200 aircraft : all certified models and all serial numbers on which modifications No 4800 or 4906 have been embodied.
The aircraft on which AIRBUS INDUSTRIE Service Bulletin A310-53-2083 Revision 2 has been embodied, are not concerned by this Airworthiness Directive.
REASON:
Aerodynamic phenomena, associated with air penetrating between the wing fairing and the fuselage cause vibrations in the upper wing fairings. A rupture of multiple fairing attachments due to fatigue could lead to fairing loss in flight, which in turn could damage the aircraft structure.
ACTION:
Before October 31, 2000 :
- add pressure bulkheads inside the fairings and
- install new seals between the fairings and the fuselage
in accordance with the instructions of AIRBUS INDUSTRIE Service Bulletin A310-53-2083, Revision 2.
REF. : AIRBUS INDUSTRIE Service Bulletin A310-53-2083 Revision 2 (or any other later approved revision).
