SUBJECT: Airworthiness Directive PL2003-08-53 SUMMARY: 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.
