Model SA-365N1, AS365-N2, AS 365 N3, and SA-366G1 helicopters, with a tail rotor blade (blade), part number 365A33- 2131-all dash numbers; 365A12-0010-all dash numbers; or 365A12-0020- 00, -01, -02, or -03; installed, certificated in any category.
This document publishes in the Federal Register an amendment adopting a superseding Airworthiness Directive (AD) 2003-08-53, sent previously to all known U.S. owners and operators of the specified Eurocopter France (Eurocopter) model helicopters by individual letters. This AD requires, in addition to the checks and tapping test inspections required in the existing AD, adding the Eurocopter Model AS 365 N3 to the applicability and correcting tail rotor blade (blade) part numbers. Also, this AD requires doing tapping tests for bonding separation on blades and removing certain blades at specified intervals. The actions specified by this AD are intended to prevent failure of a blade, loss of tail rotor control, and subsequent loss of control of the helicopter.
