14 CFR Part 39
[Docket No. FAA-2013-0213; Directorate Identifier 2012-NM-207-AD;
Amendment 39-17512; AD 2013-14-07]
RIN 2120-AA64
Airworthiness Directives; Learjet Inc. Airplanes
AGENCY: Federal Aviation Administration (FAA), DOT.
ACTION: Final rule.
-----------------------------------------------------------------------
SUMMARY: We are adopting a new airworthiness directive (AD) for certain
Learjet Inc. Model 45 airplanes. This 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 AD requires 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 issuing this AD to prevent improper sealing
of the baggage door, which could increase the risk of an uncontained
fire in the baggage compartment.
DATES: This AD is effective August 26, 2013.
The Director of the Federal Register approved the incorporation by
reference of certain publications listed in the AD as of August 26,
2013.

SUPPLEMENTARY INFORMATION:
Discussion
We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR
part 39 to include an AD that would apply to the specified products.
The NPRM published in the Federal Register on March 27, 2013 (78 FR
18529). The NPRM proposed to require modifying the fire seal on the
baggage door, including doing inspections of the fire seal for correct
contact and corrective action if necessary.
Comments
We gave the public the opportunity to participate in developing
this AD. We received no comments on the NPRM (78 FR 18529, March 27,
2013) or on the determination of the cost to the public.
Conclusion
We reviewed the relevant data and determined that air safety and
the public interest require adopting this AD as proposed.
Costs of Compliance
We estimate that this AD affects 342 airplanes of U.S. registry.
We estimate the following costs to comply with this AD:

Parts Cost per
Action Labor cost cost product Cost on U.S. operators

Modification...................... 11 work-hours x $85 $453 $1,388 $474,696
per hour = $935.
----------------------------------------------------------------------------------------------------------------
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
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),
(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.
