SUMMARY: We are adopting a new airworthiness directive (AD) for certain
Hawker Beechcraft Corporation Models 1900, 1900C, and 1900D airplanes.
This AD requires a one-time visual inspection and repetitive ultrasonic
inspections of the left and right main landing gear (MLG) actuators for
leaking and/or cracks with replacement of the actuator if leaking and/
or cracks are found. This AD results from reports of leaking and
cracked actuators. We are issuing this AD to detect and correct leaking
and cracks in the MLG actuators, which could result in loss of
hydraulic fluid. This condition could lead to an inability to extend or
lock down the landing gear, which could result in a gear up landing or
a gear collapse on landing.
DATES: This AD becomes effective on December 8, 2009.
On December 8, 2009, the Director of the Federal Register approved
the incorporation by reference of certain publications listed in this
AD.

SUPPLEMENTARY INFORMATION:
Discussion
On August 20, 2009, we issued a proposal to amend part 39 of the
Federal Aviation Regulations (14 CFR part 39) to include an AD that
would apply to certain Hawker Beechcraft Corporation Models 1900,
1900C, and 1900D airplanes. This proposal was published in the Federal
Register as a supplemental notice of proposed rulemaking (NPRM) on
August 31, 2009 (74 FR 44773). The NPRM proposed to require a one-time
visual inspection and repetitive ultrasonic inspections of the left and
right main landing gear (MLG) actuators for leaking and/or cracks with
replacement of the actuator if leaking and/or cracks are found.
Comments
We provided the public the opportunity to participate in developing
this AD. The following presents the comment received on the proposal
and FAA's response to the comment:
Comment Issue: Superseding Previous ADs
Hawker Beechcraft Corporation requests that with this AD action we
supersede AD 99-04-08 and AD 97-26-15, which affect earlier
configurations of part number 114-380041 MLG actuator. They believe
that one AD correcting all of the unsafe conditions concerned with the
MLG actuator would eliminate confusion concerning which AD to comply
with.
The FAA disagrees. We did consider supersedure of the previous two
ADs, AD 99-04-08 and AD 97-26-15. The previous two ADs and this new AD
action each address different unsafe conditions on the MLG actuators.
AD 99-04-08 concerns lubrication and replacement of the rod end, and AD
97-26-15 concerns replacement of the actuator head end cap. This new AD
action concerns replacement of the rod end cap. AD 99-04-08 uses a
prorated time of compliance starting with actuators that have
accumulated 6,000 hours time-in-service and may still apply to low
usage aircraft or aircraft that have been in storage. This current AD
action specifies compliance based on actuator cycles. The only common
feature in the three ADs is that the actuators were manufactured by
Frisby Airborne Hydraulic, Inc.
Based on the differences in the two previous ADs and in this new
AD, we determined that combining the three into a single AD would
confuse the unsafe conditions, rather than simplify them. If combined
into one AD, each unsafe condition would still have different
inspections, different
[[Page 56711]]
replacements, and different compliance times. To incorporate those
differences into a single AD would create a complicated AD to
understand. By keeping the AD actions separate, the corrective actions
for each unsafe condition can be complied with individually. For these
reasons, we decided a new AD action would be appropriate.
We will not change the final rule AD action based on this comment.
Conclusion
We have carefully reviewed the available data and determined that
air safety and the public interest require adopting the AD as proposed
except for minor editorial corrections. We have determined that these
minor corrections:
<bullet> Are consistent with the intent that was proposed in the
NPRM for correcting the unsafe condition; and
<bullet> Do not add any additional burden upon the public than was
already proposed in the NPRM.
Costs of Compliance
We estimate that this AD affects 300 airplanes in the U.S.
registry.
The ultrasonic inspection includes the time allowed for removing
and reinstalling the actuator. We estimate the following costs to do
the inspections:
----------------------------------------------------------------------------------------------------------------
Total cost per Total cost on
Labor cost Parts cost airplane U.S. operators
----------------------------------------------------------------------------------------------------------------
Visual Inspection: .5 work-hour x $80 per hour Not applicable.................. $40 $12,000
= $40.
Ultrasonic Inspection: 6 work-hours x $80 per Not applicable.................. 480 144,000
hour = $480 (If the mechanic does not remove
the actuator for the ultrasonic inspection,
the labor cost will be less.).
----------------------------------------------------------------------------------------------------------------
We estimate the following costs to do any necessary replacements
that would be required based on the results of the inspections. We have
no way of determining the number of airplanes that may need this
replacement:
------------------------------------------------------------------------
Total cost per
Labor cost Parts cost airplane
------------------------------------------------------------------------
6 work-hours x $80 per hour = $480 $4,600 per actuator. $5,080
(If the mechanic removes the
actuator for the ultrasonic
inspection, then the labor cost
will be less.).
------------------------------------------------------------------------
Authority for This Rulemaking
Title 49 of the United States Code specifies the FAA's authority to
issue rules on aviation safety. Subtitle I, Section 106 describes the
authority of the FAA Administrator. Subtitle VII, Aviation Programs,
describes in more detail the scope of the agency's authority.
We are issuing this rulemaking under the authority described in
Subtitle VII, Part A, Subpart III, Section 44701, ``General
requirements.'' Under that section, Congress charges the FAA with
promoting safe flight of civil aircraft in air commerce by prescribing
regulations for practices, methods, and procedures the Administrator
finds necessary for safety in air commerce. This regulation is within
the scope of that authority because it addresses an unsafe condition
that is likely to exist or develop on products identified in this AD.
Regulatory Findings
We have determined that this AD will not have federalism
implications under Executive Order 13132. This AD will not have a
substantial direct effect on the States, on the relationship between
the national government and the States, or on the distribution of power
and responsibilities among the various levels of government.
For the reasons discussed above, I certify that this AD:
1. Is not a ``significant regulatory action'' under Executive Order
12866;
2. Is not a ``significant rule'' under the DOT Regulatory Policies
and Procedures (44 FR 11034, February 26, 1979); and
3. Will not have a significant economic impact, positive or
negative, on a substantial number of small entities under the criteria
of the Regulatory Flexibility Act.
We prepared a summary of the costs to comply with this AD (and
other information as included in the Regulatory Evaluation) and placed
it in the AD Docket. You may get a copy of this summary by sending a
request to us at the address listed under ADDRESSES. Include ``Docket
No. FAA-2008-1312; Directorate Identifier 2008-CE-065-AD'' in your
request.
