Action
Notice of proposed rulemaking (NPRM).
Summary
We propose to adopt a new airworthiness directive (AD) for Airbus Helicopters Deutschland GmbH (Airbus Helicopters) Model EC135P1, EC135P2, EC135P2+, EC135P3, EC135T1, EC135T2, EC135T2+, and EC135T3 helicopters. This proposed AD would require replacing the retaining ring and inspecting the hoist cable hook assembly (hook). This proposed AD is prompted by a report that a hook detached from the hoist cable. The actions of this proposed AD are intended to prevent an unsafe condition on these products.
