SUPPLEMENTARY INFORMATION:
Discussion
We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR
part 39 by adding an AD that would apply to certain Beechcraft
Corporation Model G58 airplanes. The NPRM published in the Federal
Register on October 7, 2014 (79 FR 60384). The NPRM was prompted by
reports of fuel leaks due to fuel cells that did not properly fit;
improper installation of fuel components, which may cause loads on fuel
cells and breach of fuel cells; and improper installation of fuel hoses
and clamps, which may cause fuel leaks in Model G58 airplanes. The NPRM
proposed to require inspecting for and replacing, as necessary, certain
fuel cells. The NPRM also proposed to require inspecting and replacing
parts, as necessary, of the left and right fuel system installations
and correcting torques on fuel system fittings; and prohibit future
installations of certain fuel cells. We are issuing this AD to correct
the unsafe condition on these products.
Comments
We gave the public the opportunity to participate in developing
this AD. We received no comments on the NPRM (79 FR 60384, October 7,
2014) 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 except for
minor editorial changes. We have determined that these minor changes:
Are consistent with the intent that was proposed in the
NPRM (79 FR 60384, October 7, 2014) for correcting the unsafe
condition; and
Do not add any additional burden upon the public than was
already proposed in the NPRM (79 FR 60384, October 7, 2014).
Costs of Compliance
We estimate that this AD affects 18 airplanes of U.S. registry.
We estimate the following costs to comply with this AD:
[[Page 158]]
Estimated Costs
----------------------------------------------------------------------------------------------------------------
Cost per Cost on U.S.
Action Labor cost Parts cost product operators
----------------------------------------------------------------------------------------------------------------
Inspection of fuel cells *........ 12 work-hours x $85 Not Applicable....... $1,020 $5,100

information.
*** Applies to the 7 specific serial numbers on the U.S. registry, listed in the service information that must
do Part 2 of the service information.
We estimate the following costs to do any necessary installations/
replacements that are required based on the results of inspections. We
have no way of determining the number of airplanes that might need
these installations/replacements:

----------------------------------------------------------------------------------------------------------------
According to Beechcraft Corporation, some of the costs of this 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
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 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.

Adoption of the Amendment
Accordingly, under the authority delegated to me by the
Administrator, the FAA amends 14 CFR part 39 as follows:
PART 39--AIRWORTHINESS DIRECTIVES
0
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]
0
2. The FAA amends Sec. 39.13 by adding the following new airworthiness
directive (AD):
2014-26-05 Beechcraft Corporation: Amendment 39-18056; Docket No.
FAA-2014-0771; Directorate Identifier 2014-CE-006-AD.
(a) Effective Date
This AD is effective February 9, 2015.
(b) Affected ADs
None.
(c) Applicability
This AD applies to Beechcraft Corporation Model G58 airplanes,
serial numbers (SNs)
[[Page 159]]
TH-2335 through TH-2378, certificated in any category.
(d) Subject
Joint Aircraft System Component (JASC)/Air Transport Association
(ATA) of America Code: 28, Fuel.
(e) Unsafe Condition
This AD was prompted by reports of fuel leaks due to fuel cells
that did not properly fit in Model G58 airplanes. We are issuing
this AD to detect and correct improperly fitting fuel cells. We are
also issuing this AD to correct left and right fuel system
installations and set correct torque on fuel system fittings for all
affected airplanes, which if not corrected, could result in
significant fuel leakage. This could lead to an imbalance condition,
which may affect airplane controllability, and/or could lead to an
airplane fire.
(f) Compliance
Comply with this AD within the compliance times specified in
paragraphs (g) and (h), including all subparagraphs, unless already
done. All of the actions in paragraphs (g) and (h) must be completed
for compliance with this AD. The actions of Beechcraft Mandatory
Service Bulletin SB 28-4127, dated June 2013, and Beechcraft
Mandatory Service Bulletin SB 28-4131, dated November 2013, have
numerous overlapping tasks. Instead of completing the required
actions in paragraph (g) and paragraph (h) separately, you may
complete the actions of both paragraphs concurrently to avoid
repeating the same tasks unnecessarily. We recommend reviewing
Appendices 1 through 3 of this AD for general guidance and
suggestions for task ordering to assist you in not repeating tasks
unnecessarily.
