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.

List of Subjects in 14 CFR Part 39

Air transportation, Aircraft, Aviation safety, Incorporation by reference, Safety. 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**

■ 

### 1. The authority citation for part 39
continues to read as follows:

Authority: 49 U.S.C. 106(g), 40113, 44701.

**§ 39.13 [Amended]**

■ 

### 2. The FAA amends § 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)


## 159 Federal Register / Vol. 80, No. 2 / Monday, January 5, 2015 / Rules and Regulations

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.

(g) Fuel Cell Inspection

(1) For Model G58 airplanes, S/Ns TH– 2356 through TH–2378: Within the next 100 hours time-in-service (TIS) after [February 9, 2015 (the effective date of this AD) or within the next 12 months after February 9, 2015 (the effective date of this AD), whichever occurs first, inspect the fuel cells (left hand (LH) inboard, outboard, and center; and right hand (RH) inboard, outboard, and center) following Beechcraft Mandatory Service Bulletin SB 28–4131, dated November 2013.

**SUPPLEMENTARY INFORMATION** 

### :
Background

On February 14, 2012, the FAA
Modernization and Reform Act of 2012 (the Act) was signed into law. Section 403 of the Act requires U.S. air carriers to accept musical instruments on their passenger flights either as carry-on baggage or checked baggage, provided
that certain conditions are met. The passage of Section 403 is Congress’ response to difficulties musicians have encountered when transporting their instruments during air travel. The statute directs the Department of Transportation (Department or DOT) to issue a final rule to implement the requirements set forth in section 403.

During the past year, the Department has been engaged in dialogue with musicians as well as representatives of airlines and industry associations to
address the difficulties musicians face when traveling by air with musical instruments. In July 2014, DOT Secretary Anthony Foxx hosted a ‘‘Flying with Musical Instruments’’ meeting to provide airline representatives, musicians, and government officials an opportunity to exchange ideas on ways to prevent or resolve difficulties encountered by musicians when flying with their instruments while still ensuring the safety of passengers and crew. At the meeting, several members of various musician organizations described problems that musicians encounter when traveling by air with their musical instruments, particularly when bringing instruments as carry-on baggage. Airline representatives in attendance described their policies for transport of musical instruments as carry-on or checked baggage. Many airlines have already adopted policies concerning the air transportation of musical instruments that mirror the requirements in Section
403 of the Act. The stakeholders recognized that, while most airlines’ current policies regarding musical
instruments are consistent with the statute, frontline customer service agents and flight crew may not always be well-versed in those policies and may not communicate those policies accurately and effectively to musicians. By the same token, the meeting attendees also agreed that many musicians were not very well informed about airline policies regarding transporting musical instruments or about the measures they can take to
