Airworthiness Directives; Hawker Beechcraft Corporation Model G58
Airplanes
AGENCY: Federal Aviation Administration (FAA), DOT.
ACTION: Final rule.
-----------------------------------------------------------------------
SUMMARY: We are adopting a new airworthiness directive (AD) for certain
Hawker Beechcraft Corporation Model G58 airplanes. This AD requires
inspecting the installation of stand-off hardware between the heater
fuel line and the heater over-temperature sensor wires and also brake
reservoir tubing and the heater fuel pump wiring for minimum clearance
and installing acceptable stand-off hardware if stand-off hardware is
missing or inadequate. This AD results from reports received of a power
wire shorting out on the brake reservoir tube. We are issuing this AD
to detect and correct inadequate clearance of the brake reservoir
tubing and the heater fuel pump wiring, which could result in chafing
and shorting out of the electrical wiring and chafing of the tubing
carrying flammable fluids. This condition could lead to a fire in the
nose wheel well.
DATES: This AD becomes effective on April 15, 2010.
On April 15, 2010, the Director of the Federal Register approved
the incorporation by reference of certain publications listed in this
AD.

SUPPLEMENTARY INFORMATION:
Discussion
On December 8, 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 Model G58
airplanes. This proposal was published in the Federal Register as a
notice of proposed rulemaking (NPRM) on December 17, 2009 (74 FR
66930). The NPRM proposed to require inspecting the installation of
stand-off hardware between the heater fuel line and the heater over-
temperature sensor wires and also brake reservoir tubing and the heater
fuel pump wiring for minimum clearance and installing acceptable stand-
off hardware if stand-off hardware is missing or inadequate.
Comments
We provided the public the opportunity to participate in developing
this AD. The following presents the comments received on the proposal
and FAA's response to each comment:
Comment Issue No. 1: Effective Date
Mr. Busby states we should make the effective date of the AD
immediate.
The FAA disagrees. We carefully reviewed the data for this safety
concern to assess the risk level of this particular event. After
reviewing the data, we compared this safety concern with similar safety
concerns in the past. Then, we assigned a level of risk for this
particular event equivalent to the level of risk assigned to the
similar past safety concerns we used for comparison. With the
information we have at this time, we set the time frame to comply with
the actions for this AD similar to the time frame that was set for
similar safety concerns that had equivalent risk levels. Without
additional information to increase the risk level of this safety
concern we have determined that the time frame set for complying with
this safety concern is in line with past precedent.
We are not changing the final rule AD action based on this comment.
Comment Issue No. 2: Work-Hours
Mr. Busby states that the work-hours allotted to do the proposed
inspection are not enough. We infer the commenter wants us to increase
the work-hours to do the proposed inspection to relieve the pressure on
mechanics.
The FAA disagrees. For this AD, we derived the work-hours from the
Hawker Beechcraft Corporation service information. Those work-hours
were used to calculate the estimated cost impact on the owners/
operators of the affected airplanes. The FAA uses that cost estimate in
the economic analysis to determine if the AD will have a substantial
impact on small entities. In general, the direct cost to an operator is
the most significant economic consideration of an AD. Since the work-
hours in the AD are estimates for determining cost impact to the
operator, maintenance personnel may take more or less time to do the
inspection and/or maintenance as is necessary for that particular
aircraft or task. Moderately increasing the estimated work-hours for
the initial inspection does not significantly increase the cost impact
on the operator.
We are not changing 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 71 airplanes in the U.S. registry.
We estimate the following costs to do the inspection of the heater
fuel line, the heater over-temperature sensor wires, the brake
reservoir line, and the fuel heater power wire:
[[Page 11434]]
----------------------------------------------------------------------------------------------------------------
Total cost per Total cost on
Labor cost Parts cost airplane U.S. operators
----------------------------------------------------------------------------------------------------------------
1 work-hour x $85 per hour = $85............ Not applicable................ $85 $6,035
----------------------------------------------------------------------------------------------------------------
We estimate the following costs to do any necessary stand-off
hardware installation that would be required based on the results of
the inspection. We have no way of determining the number of airplanes
that may need this installation:
------------------------------------------------------------------------
Total cost
Labor cost Parts cost per airplane
------------------------------------------------------------------------
.5 work-hour x $85 per hour = $42.50.... $50 $92.50
------------------------------------------------------------------------
We estimate the following costs to do any necessary replacement of
the brake line that would be required based on the results of the
inspection. We have no way of determining the number of airplanes that
may need this installation:
------------------------------------------------------------------------
Total cost
Labor cost Parts cost per airplane
------------------------------------------------------------------------
6 work-hours x $85 per hour = $510...... $100 $610

Hawker Beechcraft Corporation will allow warranty credit as
specified in Hawker Beechcraft Mandatory Service Bulletin SB 32-3898,
dated November 2008.
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-2009-1176; Directorate Identifier 2009-CE-062-AD'' in your
request.
