AD FAA-2020-1120

The FAA proposes to adopt a new airworthiness directive (AD) for various model helicopters with certain part-numbered Goodrich externally-mounted hoist assemblies (hoists) installed. This proposed AD would require replacing unmodified hoists, installing placards, revising the existing Rotorcraft Flight Manual (RFM) for your helicopter, deactivating or removing a hoist if a partial peel out occurs, reviewing the helicopter's hoist slip load test records, repetitively inspecting the hoist cable and overload clutch (clutch), and reporting information to the FAA. This proposed AD would also require establishing operating limitations on the hoist and prohibit installing an unmodified hoist. This proposed AD was prompted by hoists failing lower load limit inspections. The actions of this proposed AD are intended to address an unsafe condition on these products.
