AD NUMBER: 2008-24-06
SUBJECT: Airworthiness Directive 2008-24-06 SUMMARY: This amendment supersedes an existing
airworthiness directive (AD) for the specified AgustaS.p.A.
(Agusta) model helicopters. This AD results from a revised
mandatory continuing airworthiness information (MCAI) issued by an
aviation authority to identify and correct an unsafe condition on
an aviation product. The aviation authority of Italy, with which we
have a bilateral agreement, reports that the previous MCAI should
not apply to newly redesigned and improved tail rotor blades. This
AD requires the same inspections as the current AD but limits the
applicability to only three part-numbered tail rotor blades. This
AD requires actions that are intended to prevent fatigue failure of
a tail rotor blade (blade), loss of a tail rotor, and subsequent
loss of control of the helicopter.
