PRODUCT: Various model helicopters with certain part-numbered and serial-numbered Goodrich externally-mounted hoists installed.
SUBJECT: Airworthiness Directive 2013-06-51
ACTION: Final Rule, Request for Comments

SUMMARY: 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.

DATES: This AD becomes effective July 15, 2013 to all persons except those persons to whom it was made immediately effective by Emergency AD (EAD) No. 2013-06-51, issued on March 25, 2013, which contained the requirements of this AD. The FAA must receive comments on this AD by August 27, 2013.
