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.

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

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

    Air transportation, Aircraft, Aviation safety, Incorporation by 
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
