## Summary

The FAA proposes to adopt a new airworthiness directive (AD) for all Airbus Helicopters Model H160-B helicopters. This proposed AD was prompted by a report of a tail rotor drive rear shaft that came into contact with its rear damper during a flight test. This proposed AD would require repetitive visual inspections of the rear damper and, depending on the results, corrective actions. The FAA is proposing this AD to address the unsafe condition on these products.
