### TITLE: POWER PLANT - AIR INTAKE COWL - INSPECTION ON T700 OF THE AIR INTAKE COWL. **CONF ALL MODIFICATIONS None REASON/DESCRIPTION/OPERATIONAL CONSEQUENCES There have been two reported events where extensive damage was found on Engine Nose Cowls most probably induced by the collapse of one inlet acoustic panel due to disbond. Inspections performed demonstrated that : - There is a disbonding in-service issue on the engine air intake cowl acoustic panels. - Several panels can be affected at any position within an intake and both intakes can be affected. - Damage can extend beyond structural Allowable Damage Limits (ADL) or current Repairable Damage Limits (RDL). This Service Bulletin is published to advise operators of A330 aircraft equipped with Trent 700 engines of the issue of ROLLS-ROYCE Service Bulletin No. RB.211-71-AG419. This Service Bulletin requires inspecting and/or repairing air intake cowl by ROLLS-ROYCE Service Bulletin No. RB.211-71-AG419. The aim of this inspection is to introduce a repetitive inspection (tap test) of the 3 inner acoustic panels of the T700 engine air intake cowl. Accomplishment of this Service Bulletin will ensure the structural integrity of the inner acoustic panels.

B. CONCURRENT REQUIREMENTS None C. REASON (1) History There have been two reported events where extensive damage was found on Engine Nose Cowls most probably induced by the collapse of one inlet acoustic panel due to disbond. Inspections performed demonstrated that : - There is a disbonding in-service issue on the engine air intake cowl acoustic panels. - Several panels can be affected at any position within an intake and both intakes can be affected. - Damage can extend beyond structural Allowable Damage Limits (ADL) or current Repairable Damage Limits (RDL). (2) Objective/Action This Service Bulletin is published to advise operators of A330 aircraft equipped with Trent 700 engines of the issue of ROLLS-ROYCE Service Bulletin No. RB.211-71- AG419.This Service Bulletin requires inspecting and/or repairing air intake cowl by ROLLSROYCE Service Bulletin No. RB.211-71-AG419. The aim of this inspection is to introduce a repetitive inspection (tap test) of the 3 inner acoustic panels of the T700 engine air intake cowl. (3) Advantages Accomplishment of this Service Bulletin will ensure the structural integrity of the inner acoustic panels. (4) Operational/Maintenance Consequences None D. DESCRIPTION To accomplish this Service Bulletin it is necessary to : Task 713024-832-801-001: Inspection (1) Do a Detailed Inspection of the Acoustic Panels on the LH Engine Air Intake Cowl.
