Airworthiness Directives; Hawker Beechcraft Corporation Model 
1900, 1900C, and 1900D Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Final rule.

-----------------------------------------------------------------------

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:
     Are consistent with the intent that was proposed in the 
NPRM for correcting the unsafe condition; and
     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.

Adoption of the Amendment

0
Accordingly, under the authority delegated to me by the Administrator, 
the Federal Aviation Administration amends part 39 of the Federal 
Aviation Regulations (14 CFR part 39) as follows:

PART 39--AIRWORTHINESS DIRECTIVES

0
1. The authority citation for part 39 continues to read as follows:

    Authority: 49 U.S.C. 106(g), 40113, 44701.


Sec.  39.13  [Amended]

0
2. FAA amends Sec.  39.13 by adding a new AD to read as follows:

2009-23-01 Hawker Beechcraft Corporation: Amendment 39-16072; Docket 
No. FAA-2008-1312; Directorate Identifier 2008-CE-065-AD.

Effective Date

    (a) This AD becomes effective on December 8, 2009.

Affected ADs

    (b) None.

Applicability

    (c) This AD applies to the airplane models and serial numbers 
listed below that are certificated in any category and equipped with 
a Hawker Beechcraft part number (P/N) 114-380041-11 (or FAA-approved 
equivalent P/N), 114-380041-13 (or FAA-approved equivalent P/N), 
114-380041-15 (or FAA-approved equivalent P/N), or 114-380041-15OVH 
main landing gear (MLG) actuator. For the purposes of this AD action 
the phrase ``or FAA-approved equivalent part number'' in this AD 
refers to any PMA part that is approved by identicality to the 
referenced part. Frisby Airborne Hydraulic, Inc. (Frisby) P/N 
1FA10043-3 has parts manufacturer approval (PMA) by identicality to 
P/N 114-380041-15; therefore, it is considered an FAA-approved 
equivalent P/N and the AD applies to airplanes with this part 
installed.

Unsafe Condition

    (d) 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.

Compliance

    (e) To address this problem, you must do the following, unless 
already done:

    Note: The phrase ``or FAA-approved equivalent part number'' in 
this AD refers to any PMA part that is approved by identicality to 
the referenced part.

     (f) If the number of cycles is unknown, calculate the 
compliance times of cycles in this AD by using hours time-in-service 
(TIS). Multiply the number of hours TIS on the MLG actuator by 4 to 
come up with the number of cycles. For the purposes of this AD:
    (1) 600 cycles equals 150 hours' TIS; and
    (2) 1,200 cycles equals 300 hours' TIS.
    (g) If cracks are found during any inspection required in 
paragraphs (e)(1), (e)(2), or (e)(3) of this AD, report the size and 
location of the cracks to the FAA within 10 days after the cracks 
are found or within 10 days after December 8, 2009 (the effective 
date of this AD), whichever occurs later.
