PRODUCT: Hawker Beechcraft Corporation Models
1900, 1900C, and 1900D Airplanes SUBJECT: Airworthiness Directive 2011-27-51 ACTION: Final rule; request for comments.
SUMMARY: This emergency AD was sent previously
to all known U.S. owners and operators of these airplanes.
This AD requires inspecting the elevator bob-weight and
attaching linkage for correct installation and for damage or
deformation to the weight and/or weight bracket with corrective
action as necessary. This AD was prompted by reports of the
elevator bob-weight (stabilizer weight) traveling past its stop
bolt, which allowed the attaching linkage to move over-center,
resulting in reduced nose down elevator control, which could result
in loss of control of the airplane.
The FAA is issuing this AD to detect and correct conditions that
could result in reduced nose down elevator control and loss of
control of the airplane.
DATES: This AD is effective January 18, 2012 to
all persons except those persons to whom it was
made immediately effective by Emergency AD 2011-27-51, issued on
December 23, 2011, which
contained the requirements of this amendment.
