Unsafe condition
This AD was prompted by reports that certain rescue hoist assemblies may have been equipped, during manufacturing or maintenance, with a non-conformant overload clutch assembly. The FAA is issuing this AD to prevent failure of the rescue hoist assembly. The unsafe condition, if not addressed, could lead to failure of the rescue hoist assembly, which could result in injury to a person being lifted or to persons on the ground.
Affected ADs
None.
