Vol. 73, No. 241
Monday, December 15, 2008
This section of the FEDERAL REGISTER
contains notices to the public of the proposed
issuance of rules and regulations. The
purpose of these notices is to give interested
persons an opportunity to participate in the
rule making prior to the adoption of the final
rules.

Airworthiness Directives; Hawker
Beechcraft Corporation Models 1900,
1900C, and 1900D Airplanes
AGENCY: Federal Aviation
Administration (FAA), Department of
Transportation (DOT).
ACTION: Notice of proposed rulemaking
(NPRM).
We propose to adopt a new
airworthiness directive (AD) for certain
Hawker Beechcraft Corporation (HBC)
Models 1900, 1900C, and 1900D
airplanes. This proposed AD would
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. This proposed
AD results from reports of leaking and
cracked actuators. We are proposing 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: We must receive comments on
this proposed AD by February 13, 2009.
ADDRESSES: Use one of the following
addresses to comment on this proposed
AD:

SUPPLEMENTARY INFORMATION:
Comments Invited
We invite you to send any written
relevant data, views, or arguments
regarding this proposed AD. Send your
comments to an address listed under the
ADDRESSES section. Include the docket
number, ‘‘FAA–2008–1312; Directorate
Identifier 2008–CE–065–AD’’ at the
beginning of your comments. We
specifically invite comments on the
overall regulatory, economic,
environmental, and energy aspects of
the proposed AD. We will consider all
comments received by the closing date
and may amend the proposed AD in
light of those comments.
We will post all comments we
receive, without change, to https://

substantive verbal contact we receive
concerning this proposed AD.
Discussion
We have received information that
two HBC 1900 series airplanes’ MLG
actuators have been found with fatigue
cracks in the end cap, which resulted in
hydraulic fluid leakage. This condition,
along with an inoperative liquid level
sensor, was found on another airplane
that landed with all landing gear up.
There have been a total of 6 reports of
leaking actuators and 13 reports of
cracked actuators.
This condition, if not corrected, could
result in leaking and cracks in the MLG
actuators, which may cause loss of
hydraulic fluid. Loss of hydraulic fluid
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.
Relevant Service Information
We have reviewed Hawker Beechcraft
Mandatory Service Bulletin SB 32–3870,
dated April 2008.
The service information describes
procedures for doing the following:
• One-time visual inspection and
repetitive ultrasonic inspections of the
MLG actuators;
• Replacement of the actuator if
leaking and/or cracks are found; and
• Reporting the size and location of
cracks to HBC if any are found during
the inspections.
FAA’s Determination and Requirements
of the Proposed AD
We are proposing this AD because we
evaluated all information and
determined the unsafe condition
described previously is likely to exist or
develop on other products of the same
type design. This proposed AD would
require a one-time visual inspection of
the left and right main landing gear
(MLG) actuators and repetitive
ultrasonic inspections of the left and
right MLG actuators for leaking and/or
cracks with replacement of the actuator
if leaking and/or cracks are found.
Costs of Compliance
We estimate that this proposed AD
would affect 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 proposed
inspections:
Total cost per
airplane
Labor cost
Parts cost
Visual Inspection: .5 work-hour × $80 per hour = $40 ..............................

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 rulemaking
action.
Regulatory Findings
dwashington3 on PROD1PC60 with PROPOSALS
We have determined that this
proposed AD would not have federalism
implications under Executive Order
13132. This proposed AD would 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 the proposed regulation:
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 regulatory evaluation
of the estimated costs to comply with
this proposed AD and placed it in the
AD docket.
Examining the AD Docket
You may examine the AD docket that
contains the proposed AD, the
regulatory evaluation, any comments
received, and other information on the
Internet at https://www.regulations.gov;
or in person at the Docket Management
Facility between 9 a.m. and 5 p.m.,
Monday through Friday, except Federal
holidays. The Docket Office (telephone
(800) 647–5527) is located at the street
address stated in the ADDRESSES section.
Comments will be available in the AD
docket shortly after receipt.

SUMMARY: We propose to adopt a new airworthiness directive (AD) for
certain Hawker Beechcraft Corporation (HBC) Models 1900, 1900C, and
1900D airplanes. This proposed AD would 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. This
proposed AD results from reports of leaking and cracked actuators. We
are proposing 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.

Discussion
We have received information that two HBC 1900 series airplanes'
MLG actuators have been found with fatigue cracks in the end cap, which
resulted in hydraulic fluid leakage. This condition, along with an
inoperative liquid level sensor, was found on another airplane that
landed with all landing gear up. There have been a total of 6 reports
of leaking actuators and 13 reports of cracked actuators.
This condition, if not corrected, could result in leaking and
cracks in the MLG actuators, which may cause loss of hydraulic fluid.
Loss of hydraulic fluid 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.
Relevant Service Information
We have reviewed Hawker Beechcraft Mandatory Service Bulletin SB
32-3870, dated April 2008.
The service information describes procedures for doing the
following:
One-time visual inspection and repetitive ultrasonic
inspections of the MLG actuators;
Replacement of the actuator if leaking and/or cracks are
found; and
Reporting the size and location of cracks to HBC if any
are found during the inspections.
FAA's Determination and Requirements of the Proposed AD
We are proposing this AD because we evaluated all information and
determined the unsafe condition described previously is likely to exist
or develop on other products of the same type design. This proposed AD
would require a one-time visual inspection of the left and right main
landing gear (MLG) actuators and repetitive ultrasonic inspections of
the left and right MLG actuators for leaking and/or cracks with
replacement of the actuator if leaking and/or cracks are found.
Costs of Compliance
We estimate that this proposed AD would affect 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 proposed 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.
[[Page 75978]]
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 proposed
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 = $4,600 per actuator. $5,080
$480 (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
rulemaking action.
Regulatory Findings
We have determined that this proposed AD would not have federalism
implications under Executive Order 13132. This proposed AD would 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 the proposed
regulation:
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 regulatory evaluation of the estimated costs to
comply with this proposed AD and placed it in the AD docket.
Examining the AD Docket
You may examine the AD docket that contains the proposed AD, the
regulatory evaluation, any comments received, and other information on
the Internet at https://www.regulations.gov; or in person at the Docket
Management Facility between 9 a.m. and 5 p.m., Monday through Friday,
except Federal holidays. The Docket Office (telephone (800) 647-5527)
is located at the street address stated in the ADDRESSES section.
Comments will be available in the AD docket shortly after receipt.
