AGENCY: Federal Aviation
Administration, DOT.
ACTION: Final rule; request for
comments.
SUMMARY: This document publishes in
the Federal Register an amendment
adopting Airworthiness Directive (AD)
2010-19-51, which was sent previously
to all known U.S. owners and operators
of the specified model Bell Helicopter
Textron Canada (Bell) helicopters by
individual letters. This AD requires
inspecting parts of the main rotor
hydraulic servo actuator (servo actuator)
for certain conditions and replacing any
unairworthy parts before further flight.
This AD is prompted by a collective
servo actuator malfunction and a
subsequent investigation that revealed
the output piston rod assembly (piston
rod) had fractured at the threaded end
because of stress corrosion cracking.
Also, during the investigation of that
servo actuator malfunction, a
nonconforming grind relief was
discovered on a separate piston rod. The
actions specified by this AD are
intended to detect corrosion or a
nonconforming piston rod that, if not
detected and corrected, could result in
failure of the piston rod, failure of the
servo actuator, and subsequent loss of
control of the helicopter.
DATES: Effective December 9, 2010, to all
persons except those persons to whom
it was made immediately effective by
Emergency AD 2010-19-51, issued on
August 31, 2010, which contained the
requirements of this amendment.
The incorporation by reference of
certain publications listed in the
regulations is approved by the Director
of the Federal Register as of December
9, 2010.

SUPPLEMENTARY INFORMATION: On August
31, 2010, the FAA issued Emergency AD
2010-19-51 for the specified model
helicopters, which requires inspecting
parts of the servo actuator for certain
conditions and replacing any
unairworthy parts before further flight.
That action was prompted by a
collective servo actuator malfunction
and a subsequent investigation that
revealed the output piston rod assembly
(piston rod) had fractured at the
threaded end because of stress corrosion
cracking. Also, during the investigation
of that servo actuator malfunction, a
nonconforming grind relief was
discovered on a separate piston rod.
This condition, if not detected and
corrected, could result in failure of the
piston rod, failure of the servo actuator,
and subsequent loss of control of the
helicopter.
