Airworthiness Directives; Beechcraft Corporation Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Final rule.

-----------------------------------------------------------------------

SUMMARY: We are adopting a new airworthiness directive (AD) for certain 
Beechcraft Corporation Model G58 airplanes. This AD was prompted by 
reports of fuel leaks due to fuel cells that did not properly fit in 
Model G58 airplanes. This AD requires inspecting for and replacing, as 
necessary, certain fuel cells. This AD also requires inspecting and 
replacing parts, as necessary, of the left and right fuel system 
installations and correcting torques on fuel system fittings; and 
prohibits future installations of certain fuel cells. We are issuing 
this AD to correct the unsafe condition on these products.

DATES: This AD is effective February 9, 2015.
    The Director of the Federal Register approved the incorporation by 
reference of certain publications listed in this AD as of February 9, 
2015.

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:

    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.
