## Summary

The FAA proposes to adopt a new airworthiness directive (AD) for all Airbus Helicopters Model AS355E, AS355F, AS355F1, AS355F2, and AS355N helicopters. This proposed AD was prompted by a report of a partially broken tail rotor drive fan support (fan support) and a completely broken fan support. This proposed AD would require repetitively inspecting certain part-numbered fan supports (affected parts), and depending on the results, removing an affected part from service and replacing it with a serviceable part, which constitutes terminating action for the repetitive inspections. This proposed AD would also require replacing affected parts with serviceable parts unless already accomplished and prohibit installing an affected part on any helicopter, as specified in a European Union Aviation Safety Agency (EASA) AD, which is proposed for incorporation by reference. The FAA is proposing this AD to address the unsafe condition on these products.
