Airworthiness Directives; Airbus Helicopters Deutschland GmbH Helicopters

FAA / Federal Register · 2020-26253

The FAA proposes to adopt a new airworthiness directive (AD) for certain Airbus Helicopters Deutschland GmbH Model EC135P1, EC135P2, EC135P2+, EC135P3, EC135T1, EC135T2, EC135T2+, and EC135T3 helicopters. This proposed AD would require removing certain Titanium (Ti) bolts from service and prohibit installing these Ti-bolts in a critical area. This proposed AD was prompted by a report of a broken Ti-bolt. The FAA is proposing this AD to address the unsafe condition on these products.
