## Summary

We propose to adopt a new airworthiness directive (AD) for certain Airbus Model A330-243, -243F, -341, -342, and -343 airplanes equipped with Rolls-Royce Trent 700 engines. This proposed AD was prompted by reports of extensive damage to engine air intake cowls as a result of acoustic panel collapse. This proposed AD would require repetitive inspections of the three inner acoustic panels of both engine air intake cowls to detect disbonding, and corrective actions if necessary. We are proposing this AD to detect and correct disbonding, which could result in detachment of the engine air intake cowl from the engine leading to ingestion of parts, which could cause failure of the engine, and consequent reduced controllability of the airplane.
