RIN 2120-AA64
Airworthiness Directives; Hawker Beechcraft Corporation Airplanes
AGENCY: Federal Aviation Administration (FAA), DOT.
ACTION: Notice of proposed rulemaking (NPRM).
-----------------------------------------------------------------------
SUMMARY: We propose to adopt a new airworthiness directive (AD) for
certain Hawker Beechcraft Corporation Model C90GTi (King Air)
airplanes. This proposed AD was prompted by reports of incorrect gauge
wires used in certain wiring bundles for the cockpit electrical power
for backlighting and instrument panel components. This proposed AD
would require replacing incorrect gauge wires in certain electrical
power wiring bundles, inspecting associated wiring bundles and
components for heat damage, and taking all necessary corrective
actions. We are proposing this AD to correct the unsafe condition on
these products.

SUPPLEMENTARY INFORMATION:
Comments Invited
We invite you to send any written relevant data, views, or
arguments about this proposal. Send your comments to an address listed
under the ADDRESSES section. Include ``Docket No. FAA-2012-0830;
Directorate Identifier 2012-CE-026-AD'' at the beginning of your

[[Page 47571]]
economic, environmental, and energy aspects of this proposed AD. We
will consider all comments received by the closing date and may amend
this proposed AD because of those comments.
We will post all comments we receive, without change, to http://www.regulations.gov, including any personal information you provide. We
will also post a report summarizing each substantive verbal contact we

Discussion
We received a report that a Hawker Beechcraft Corporation Model
C90GTi (King Air) airplane experienced an in-flight lighting failure of
the pilot panel, audio panel, flight guidance control panel, and
display control panel lighting.
Investigation revealed that incorrect gauge wires were used by the
wiring fabricators in the wiring bundles for the pilot backlighting and
instrument panel components. The specific pilot backlighting systems
directly affected by the incorrect gauge wiring bundles are the
backlighting for the pilot panel (reversionary switching, radio tuning
unit, multifunction display (MFD), pilot yoke lights, pilot's primary
flight display (PFD)), audio panel, flight guidance control panel, and
display control panel. The instrument panel components affected include
the MFD and the co-pilot's PFD.
This condition, if not corrected, could result in smoke in the
cockpit and possibly cause wiring failure for the power to the
airplane's cockpit lighting, the MFD, the co-pilot's PFD, and their
respective systems. Failure of the wiring for the power to the
airplane's cockpit backlighting, the MFD, and the co-pilot's PFD
systems could also result in potential damage to surrounding wires and
components.
Relevant Service Information
We reviewed Hawker Beechcraft Mandatory Service Bulletin No. SB 24-
4050, dated November 2010. The service bulletin describes procedures
for replacing incorrect gauge wires in the electrical power wiring
bundles, inspecting the associated wire bundles and components for heat
damage, and taking any necessary corrective actions.
FAA's Determination
We are proposing this AD because we evaluated all the relevant
information and determined the unsafe condition described previously is
likely to exist or develop in other products of the same type design.
Proposed AD Requirements
This proposed AD would require accomplishing the actions specified
in the service information described.
Costs of Compliance
We estimate that this proposed AD affects 85 airplanes of U.S.
registry.
We estimate the following costs to comply with this proposed AD:
Estimated costs
----------------------------------------------------------------------------------------------------------------
Cost per Cost on U.S.
Action Labor cost Parts cost product operators
----------------------------------------------------------------------------------------------------------------
Replace incorrect gauge wires and 15 work-hours x $85 per $50 $1,325 $112,625
damaged components. hour = $1,275.
----------------------------------------------------------------------------------------------------------------
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 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 this 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),
(3) Will not affect intrastate aviation in Alaska, and
(4) 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.
List of Subjects in 14 CFR Part 39

reference, Safety.
The Proposed Amendment
Accordingly, under the authority delegated to me by the
Administrator, the FAA proposes to amend 14 CFR part 39 as follows:
PART 39--AIRWORTHINESS DIRECTIVES
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]
2. The FAA amends Sec. 39.13 by adding the following new
airworthiness directive (AD):
Hawker Beechcraft Corporation: Docket No. FAA-2012-0830; Directorate
Identifier 2012-CE-026-AD.
(a) Comments Due Date
We must receive comments by September 24, 2012.
(b) Affected ADs
None.
(c) Applicability
This AD applies to Hawker Beechcraft Corporation Model C90GTi
(King Air) airplanes, serial numbers LJ-1847, and LJ-1853 through

(d) Subject
Joint Aircraft System Component (JASC)/Air Transport Association
(ATA) of America Code 24; Electric power.
[[Page 47572]]
(e) Unsafe Condition
This AD was prompted by reports of incorrect gauge wires used in
the wiring bundles for the cockpit electrical power for backlighting
and instrument panel components. We are issuing this AD to prevent
failure of the wiring for the power to the airplane's cockpit
backlighting and instrument panel components. Failure of the wiring
for the airplane's cockpit backlighting and instrument panel
components could cause smoke in the cockpit, loss of power to the
multifunction display, the co-pilot's primary flight display,
cockpit lighting, and potential damage to surrounding wires and
components.
