Airworthiness Directive 2013-06-51
one-timeAirworthiness Directives; Various Helicopter Models
What this AD requires
We are publishing a new airworthiness directive (AD) for various model helicopters with certain part-numbered and serial- numbered Goodrich externally-mounted hoists installed. This AD requires performing a cable conditioning lift and a load inspection test, deactivating or replacing any hoist that fails the load inspection test, and recording the results of the load inspection test. This AD is prompted by a report of a failure of the overload clutch resulting in an in-flight failure of a hoist containing a dummy load during a maintenance flight. These actions are intended to detect conditions that may result in failure of the hoist and injury to persons being lifted.
Which aircraft AD 2013-06-51 applies to
Applies to any helicopter, of any make/model (the listed makes/models are illustrative only, 'including but not limited to'), certificated in any category, with an externally-mounted hoist bearing a part number and serial number listed in Table 1 of Goodrich Alert Service Bulletin No. 44301-10-15, dated March 8, 2013, installed. Unsafe condition is failure of the hoist overload clutch.
Whether AD 2013-06-51 actually applies to your aircraft (by serial and installed parts) and whether it’s already complied with comes from that aircraft’s records.
How AD compliance is recorded
A valid compliance record (14 CFR 43.9) states:
Tailplate reads a tail number’s logbooks and matches every applicable AD — including this one — to its compliance evidence, with recurring next-due dates computed.
