improve the performance of computer 

safety models that simulate postulated 

SFP accident/fire scenarios. The 

petition states that the fourth proposed 

regulation would require that licensees 

use conservative SFP accident 

evaluation models to perform annual 

SFP safety evaluations of postulated 

complete LOCA scenarios, postulated 

partial LOCA scenarios, and postulated 

boil-off accident scenarios. The petition 

states that the purpose of these 

evaluations would be to keep the NRC 

informed of the potential consequences 

of postulated SFP accident/fire 

scenarios as fuel assembles were added, 

removed, or reconfigured in licensees’ 

SFPs.

SUPPLEMENTARY INFORMATION: On 

September 12, 2014, FHFA published in 

the Federal Register a notice of 

proposed rulemaking and request for 

comments proposing to revise its 

regulations governing Bank 

membership, located at 12 CFR part 

1263. See 79 FR 54847 (Sept. 12, 2014). 

Primarily, the proposed rule would 

revise part 1263 to: (1) Require each 

Bank member institution and each 

applicant for Bank membership to hold 

one percent of its assets in ‘‘home 

mortgage loans’’ (as that term is defined 

in proposed part 1263) in order to 

satisfy the statutory requirement that an 

institution make long-term home 

mortgage loans to be eligible for 

membership; (2) require each member to 

comply on an ongoing basis, rather than 

only at the time of application as at 

present, with the foregoing requirement 

and, where applicable, with the 

requirement that it have at least 10 

percent of its assets in ‘‘residential 

mortgage loans’’ (as defined in proposed 

part 1263); (3) define the term 

‘‘insurance company’’ to exclude 

captive insurers from Bank membership, 

but permit existing captive members to 

remain members for five years with 

certain restrictions on their ability to 

obtain advances; (4) require a Bank to 

obtain and review an insurance 

company’s audited financial statements 

when considering it for membership; 

and (5) clarify the standards by which 

an insurance company’s ‘‘principal 

place of business’’ is to be identified in 

determining the appropriate Bank 

district for membership. 

The comment period for the proposed 

rule was originally set to expire on 

November 12, 2014. However, FHFA 

has received numerous requests from 

the Banks and from other interested 

parties for additional time to review the 

rule and provide comments. In response 

to these requests, FHFA is extending the 

comment period by an additional 60 

days. This will result in a total comment 

period of 120 days, which will expire on 

January 12, 2015. 

Dated: October 1, 2014.

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Notice of proposed rulemaking 

(NPRM). 

SUMMARY: We propose to adopt a new 

airworthiness directive (AD) for certain 

Beechcraft Corporation Model G58 

airplanes. This proposed AD was 

prompted by reports of fuel leaks due to 

fuel cells that did not properly fit in 

Model G58 airplanes. This proposed AD 

would require inspecting for and 

replacing, as necessary, certain fuel 

cells. This proposed AD would also 

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 proposing this AD to 

correct the unsafe condition on these 

products. 

DATES: We must receive comments on 

this proposed AD by November 21, 

2014.

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– 

2014–0771; Directorate Identifier 2014– 

CE–006–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 seven reports of fuel 

leaks in Beechcraft Corporation Model 

G58 airplanes. Six fuel leaks were 

observed before takeoff or after landing. 

One in-flight fuel leak caused large and 

rapid loss of fuel and a 24-gallon fuel 

imbalance. 

An investigation found issues that 

may have occurred on the production 

line, including fuel cell fit 

inconsistencies; 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. 

Further investigation found 

discrepancies and variation in the fit of 

the fuel cell on airplanes produced after 

December 2011. 

These conditions, 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. 

Relevant Service Information 

We reviewed Beechcraft Mandatory 

Service Bulletin SB 28–4127, dated June 

2013; and Beechcraft Mandatory Service 

Bulletin SB 28–4131, dated November 

2013. The service information describes 

procedures for inspection of the left and 

right fuel system installations and 

replacement of parts, as necessary; 

inspection for proper torque on fuel 

system fittings; and inspection and 

replacement, as necessary, of fuel cells. 

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. This proposed AD will only 

affect fuel cells installed on airplanes 

produced after December 2011. This 

proposed AD would include prohibiting 

the installation of both Beechcraft fuel 

cell part numbers produced by FFC and 

any PMA part numbers on the Model 

G58 airplanes serial numbers (SNs) TH– 

2335 through TH–2378, certificated in 

any category. 

We are evaluating the Beechcraft and 

PMA fuel cells that are installed on 

airplanes prior to December 2011 for the 

same or similar condition and may take 

future rulemaking action for airplanes 

incorporating these parts. 

Proposed AD Requirements 

This proposed AD would require 

accomplishing the actions specified in 

the service information described 

previously and prohibit the installation 

of certain Beechcraft and FFC PMA fuel 

cells. 

Costs of Compliance 

We estimate that this proposed AD 

affects 18 airplanes of U.S. registry. 

We estimate the following costs to 

comply with this proposed AD: 

ESTIMATED COSTS

Action Labor cost Parts cost Cost per 

product 

Cost on U.S.

*** 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/

based on the results of proposed 

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 proposed 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 

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.

The Proposed Amendment 

Accordingly, under the authority 

delegated to me by the Administrator, 

the FAA proposes to amend 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): 

Beechcraft Corporation: Docket No. FAA– 

2014–0771; Directorate Identifier 2014– 

CE–006–AD. 

(a) Comments Due Date 

We must receive comments by November 

21, 2014. 

(b) Affected ADs 

None. 

(c) Applicability 

This AD applies to Beechcraft Corporation 

Model G58 airplanes, serial numbers (SNs) 

TH–2335 through TH–2378, certificated in 

any category. 


asabaliauskas on DSK5VPTVN1PROD with RULES
Federal Register / Vol. 79, No. 194 / Tuesday, October 7, 2014 / Proposed Rules 60387 

(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 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 TIS after the effective date of this AD 

or within the next 12 months after 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. If any fuel

Mandatory Service Bulletin SB 28–4131, 

dated November 2013. 

(2) For Model G58 airplanes, S/Ns TH– 

2335 through TH–2378: as of the effective 

date of this AD, do not install the following 

P/Ns: 

(i) Beechcraft Corporation P/N 60–921046– 

5, 60–921046–6, 002–920034–9, 002–

(h) Fuel System Inspection 

Certain Model G58 airplanes, as listed in 

paragraphs (h)(1), (h)(2), and (h)(3) of this 

AD, may have incorrect left and right fuel 

system installations and incorrect torque on 

fuel system fittings. 

(1) For Model G58 airplanes, SNs TH–2335, 

TH–2338 through TH–2348, TH–2351 

through TH–2359, TH–2362 through TH– 

2366, TH–2369, and TH–2371 that are 

already in compliance with Part 1 of the 

Accomplishment Instructions in Beechcraft 

Mandatory Service Bulletin SB 28–4127,

Discussion 

The Federal Office of Civil Aviation 

(FOCA), which is the aviation authority 

for Switzerland, has issued AD HB– 

2014–001, dated July 25, 2014 (referred 

to after this as ‘‘the MCAI’’), to correct 

an unsafe condition for PILATUS 

Aircraft Ltd. Model PC–7 airplanes and 

was based on mandatory continuing 

airworthiness information originated by 

an aviation authority of another country. 

The MCAI states: 

This Airworthiness Directive (AD) is 

prompted due to the possibility of cracks in 


asabaliauskas on DSK5VPTVN1PROD with RULES
