## Summary

The FAA proposes to adopt a new airworthiness directive (AD) for all Airbus Helicopters Model EC120B helicopters. This proposed AD was prompted by a report of corrosion found on the external tail boom skin, under the Very High Frequency (VHF) antenna. This proposed AD would require inspecting the tail boom at the VHF antenna attachments and depending on the results, repairing or modifying the tail boom skin, as specified in a European Union Aviation Safety Agency (EASA) AD, which is proposed for incorporation by reference (IBR). The FAA is proposing this AD to address the unsafe condition on these products.
