Airworthiness Directives; Hawker Beechcraft Corporation (Type
Certificate Previously Held by Raytheon Aircraft Company; Beech
Aircraft 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 (Type Certificate previously held
by Raytheon Aircraft Company; Beech Aircraft Corporation) Model 400A
airplanes. This proposed AD was prompted by a report that the wiring
for the 5-volt direct current (DC) system is undersized and does not
have adequate circuit protection for the smaller gauge wire. This
proposed AD would require installing an in-line fuse in the 5-volt DC
system for each of the five instrument lighting control power supplies.
We are proposing this AD to prevent failure of the wiring, which could
result in smoke in the cockpit, loss of cockpit lighting, and potential
damage to surrounding wiring for other cockpit equipment such as the
stick shaker function or angle-of-attack indicators.
DATES: We must receive comments on this proposed AD by December 20,
2012.
ADDRESSES: You may send comments, using the procedures found in 14 CFR
11.43 and 11.45, by any of the following methods:

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-2012-1111;
Directorate Identifier 2012-NM-114-AD'' at the beginning of your
comments. We specifically invite comments on the overall regulatory,
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
receive about this proposed AD.
Discussion
We received a report that the wiring for the 5-volt DC system is
undersized and does not have adequate circuit protection for the
smaller gauge wire. The wire is adequate for normal electrical loads,
but it cannot safely handle the power supply's maximum current. This
condition, if not corrected, could result in failure of the wiring,
which could result in smoke in the cockpit, loss of cockpit lighting,
and potential damage to surrounding wiring for other cockpit equipment
such as the stick shaker function or angle-of-attack indicators.
Relevant Service Information
We reviewed Hawker Beechcraft Mandatory Service Bulletin SB 33-
4002, dated October 2010. The service information describes procedures
for installing an in-line fuse in the 5-volt DC system for each of the
five instrument lighting control power supplies.
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 previously.
Clarification of Service Bulletin Note
The Hawker Beechcraft Mandatory Service Bulletin SB 33-4002, dated
October 2010, includes a note in the Accomplishment Instructions to
inform operators to contact Hawker Beechcraft ``should any difficulty
be encountered''
[[Page 66412]]
in accomplishing the service bulletin. We have included a statement in
paragraph (g) of this proposed AD to clarify that any deviation from
the instructions provided in that service bulletin must be approved as
an alternative method of compliance under paragraph (i) of this
proposed AD.
Costs of Compliance
We estimate that this proposed AD affects 421 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
----------------------------------------------------------------------------------------------------------------
Installation.............................. 10 work-hours x $85 per hour $285 $1,135 $477,835
= $850.
----------------------------------------------------------------------------------------------------------------
According to the manufacturer, some of the costs of this proposed
AD may be covered under warranty, thereby reducing the cost impact on
affected individuals. We do not control warranty coverage for affected
individuals. As a result, we have included all costs in our cost
estimate.
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.
