DEPARTMENT OF TRANSPORTATION
Federal Aviation Administration
14 CFR Part 39
[Docket No. FAA-2013-0213; Directorate Identifier 2012-NM-207-AD]
RIN 2120-AA64
Airworthiness Directives; Learjet Inc. 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 Learjet Inc. Model 45 airplanes. This proposed AD was prompted
by a report that the fire barrier seal on the external baggage door
does not seal the surrounding door structure due to incorrect
positioning of the barrier. This proposed AD would require modifying
the fire seal on the baggage door, including doing inspections of the
fire seal for correct contact and corrective action if necessary. We
are proposing this AD to prevent improper sealing of the baggage door,
which could increase the risk of an uncontained fire in the baggage
compartment.
DATES: We must receive comments on this proposed AD by May 13, 2013.
ADDRESSES: You may send comments, using the procedures found in 14 CFR
11.43 and 11.45, by any of the following methods:
Federal eRulemaking Portal: Go to http://www.regulations.gov. Follow the instructions for submitting comments.

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-2013-0213;
Directorate Identifier 2012-NM-207-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 fire barrier seal on the external
baggage door does not seal the surrounding door structure due to
incorrect positioning of the barrier. Further investigation revealed
that there is a deficiency in the original design of the door which
does not allow correct positioning of the fire barrier seal against the
baggage door opening. This condition, if not corrected, could result in
the increased risk of an uncontained fire in the baggage compartment.
Relevant Service Information
We reviewed Bombardier Service Bulletins 40-25-25 and 45-25-35,
both Revision 3, both dated February 6, 2012. The service information
describes procedures for modifying the fire barrier seal on the baggage
door, including doing a general visual inspection of the fire seal for
correct contact, and corrective actions if necessary. The modification
includes, among other things, modifying the existing bracket assembly
and installing an adjustable clip on the bracket. The corrective
actions include adjusting the door clip and seal retainer and adjusting
the seal.
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.
Costs of Compliance
We estimate that this proposed AD affects 342 airplanes of U.S.
registry.
We estimate the following costs to comply with this proposed AD:

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.
