## Summary

We propose to adopt a new airworthiness directive (AD) for all Airbus Model A330-243, -243F, -342, and -343 airplanes. This proposed AD was prompted by reports of cracking of air intake cowls on Rolls- Royce Trent engines, worn and detached attachment links, and fractured thermal anti-ice (TAI) piccolo tubes. This proposed AD would require inspecting piccolo tubes, piccolo tube mount links, the aft side of the forward bulkhead, and outer boundary angles (OBA) for cracks, fractures, and broken links, and corrective actions if necessary. We are proposing this AD to prevent degraded structural integrity of the engine nose cowl and a broken piccolo tube, which could lead to in- flight damage of the engine and reduced thermal anti-ice performance.
