Federal Register / Vol. 80, No. 121 / Wednesday, June 24, 2015 / Proposed Rules 36255 

Could we amend the scope of a rule to 

clarify its applicability or to reduce the 

burden, while remaining faithful to 

statutory intent? If so, specify which 

regulation(s) should be clarified. 

• Burden on small insured 

institutions. The Board has a particular 

interest in minimizing burden on small 

insured credit unions (those with less 

than $50 million in assets). NCUA 

solicits comment on whether any 

regulations within these categories 

should be continued without change, 

amended or rescinded in order to 

minimize any significant economic 

impact the regulations may have on a 

substantial number of small federally 

insured credit unions.

Airworthiness Directives; The Boeing 

Company Airplanes 

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Notice of proposed rulemaking 

(NPRM). 

SUMMARY: We propose to supersede 

Airworthiness Directive (AD) 2005–01– 

09, which applies to certain The Boeing 

Company Model 747–100, 747–100B, 

747–100B SUD, 747–200B, 747–200C, 

747–200F, 747–300, 747–400, 747– 

400D, 747–400F, and 747SR series 

airplanes. AD 2005–01–09 requires a 

one-time detailed inspection for 

discrepancies of the frame web and 

inner chords on the forward edge frame 

of the number 5 main entry door cutout, 

and corrective action if necessary. Since 

we issued AD 2005–01–09, additional 

cracking was found in the same area 

after completion of the one-time 

detailed inspection. This proposed AD 

would add repetitive high frequency 

eddy current inspections for cracking of 

the frame inner chords (forward and 

aft), and corrective action if necessary. 

We are proposing this AD to detect and 

correct discrepancies of the frame web 

and inner chords, which could result in 

cracking, subsequent severing of the 

frame, and consequent rapid 

depressurization of the airplane. 

DATES: We must receive comments on 

this proposed AD by August 10, 2015. 

ADDRESSES: You may send comments, 

using the procedures found in 14 CFR 

11.43 and 11.45, by any of the following

Discussion 

On December 27, 2004, we issued AD 

2005–01–09, Amendment 39–13933 (70 

FR 1340, January 7, 2005), for certain 

The Boeing Company Model 747–100, 

747–100B, 747–100B SUD, 747–200B, 

747–200C, 747–200F, 747–300, 747– 

400, 747–400D, 747–400F, and 747SR 

series airplanes. AD 2005–01–09 

requires a one-time inspection for 

discrepancies of the frame web and 

inner chords on the forward edge frame 

of the number 5 main entry door cutout, 

and corrective action if necessary. AD 

2005–01–09 resulted from a report of 

cracking of the frame web and inner 

chords on the forward edge frame of the 

number 5 main entry door. We issued 

AD 2005–01–09 to find and fix 

discrepancies of the frame web and 

inner chords, which could result in 

cracking, subsequent severing of the 

frame, and consequent rapid 

depressurization of the airplane. 

Actions Since AD 2005–01–09, 

Amendment 39–13933 (70 FR 1340, 

January 7, 2005), Was Issued 

Since we issued AD 2005–01–09, 

Amendment 39–13933 (70 FR 1340, 

January 7, 2005), additional cracking 

was found in the same area after 

completion of the one-time detailed 

inspection required by AD 2005–01–09. 

Related Service Information Under 1 

CFR Part 51 

We reviewed and approved Boeing 

Alert Service Bulletin 747–53A2494, 

Revision 1, dated January 9, 2015. The 

service information describes 

procedures for a one-time detailed 

inspection and repetitive surface high 

frequency eddy current inspections of 

the Station 2231 frame inner chords 

(forward and aft), and repair of 

discrepancies. This service information 

is reasonably available because the 

interested parties have access to it 

through their normal course of business 

or by the means identified in the 

ADDRESSES section of this NPRM. 

Related AD 

On August 16, 2013, we issued AD 

2013–17–08, Amendment 39–17572 (78 

FR 57053, September 17, 2013), for 

certain The Boeing Company Model 

747–100, 747–100B, 747–100B SUD, 

747–200B, 747–200C, 747–200F, 747– 

300, 747–400, 747–400D, 747–400F, and 

747SR series airplanes. AD 2013–17–08 

requires repetitive inspections to find 

cracking of the web, strap, inner chords, 

inner chord angle of the forward edge 

frame of the number 5 main entry door 

cutouts; the frame segment between 

stringers 16 and 31; repair if necessary; 

and repetitive inspections for cracking 

of repairs. AD 2013–17–08 resulted from 

multiple reports of cracking outside of 

the previous inspection areas and a 

report of a crack that initiated at the aft 

edge of the inner chord rather than 

initiating at a fastener location. We 

issued AD 2013–17–08 to detect and 

correct such cracks, which could cause 

damage to the adjacent body structure 

and could result in depressurization of 

the airplane in flight. 

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. 

Proposed AD Requirements 

Although this proposed AD does not 

explicitly restate the requirements of AD 

2005–01–09, Amendment 39–13933 (70 

FR 1340, January 7, 2005), this proposed 

AD would retain all of the requirements. 

Those requirements are referenced in 

the service information identified 

previously, which, in turn, is referenced 

in paragraph (g) of this proposed AD. 

This proposed AD would require 

accomplishing the actions specified in 

the service information described 

previously, except as discussed under 

‘‘Difference Between this Proposed AD 

and the Service Bulletin.’’ Refer to this 

service information for information on 

the procedures and compliance times. 

Difference Between This Proposed AD 

and the Service Bulletin 

Although Boeing Alert Service 

Bulletin 747–53A2494, Revision 1, 

dated January 9, 2015, specifies that 

operators may contact the manufacturer 

for disposition of certain repair 

conditions, this proposed AD would 

require repairing those conditions in 

one of the following ways: 

• In accordance with a method that 

we approve; or 

• Using data that meet the 

certification basis of the airplane, and 

that have been approved by the Boeing 

Commercial Airplanes Organization 

Designation Authorization (ODA) whom 

we have authorized to make those 

findings. 

Costs of Compliance 

We estimate that this proposed AD 

affects 174 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. operators 

Detailed inspection ........ 2 work-hours × $85 per hour = $170 ................. $0 $170 ............................. $29,580. 

HFEC inspections ......... 4 work-hours × $85 per hour = $340 ................. 0 $340 per inspection 

cycle.

$59,160 per inspection 

cycle. 

We have received no definitive data 

that would enable us to provide a cost 

estimate for the on-condition actions 

specified in this proposed AD. 

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 have 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 that the 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.

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Notice of proposed rulemaking 

(NPRM). 

SUMMARY: We propose to adopt a new 

airworthiness directive (AD) for all The 

Boeing Company Model 737–100, –200, 

–200C, –300, –400, and –500 series 

airplanes. This proposed AD was 

prompted by a report of a crack of the 

forward leg of the left front spar lower 

chord and cracks on the lower wing skin 

at three fastener holes common to the 

nacelle outboard side load fitting. This 

proposed AD would require repetitive 

inspections for cracks on the front spar 

lower chord, inspar skin, and wing skin, 

and corrective action if necessary. We 

are proposing this AD to detect and 

correct fatigue cracking of the forward 

leg of the front spar lower chord, inspar 

skin, and wing skin common to the 

nacelle outboard side load fitting, which 

could adversely affect the structural 

integrity of the wing. 

DATES: We must receive comments on 

this proposed AD by August 10, 2015. 

ADDRESSES: You may send comments, 

using the procedures found in 14 CFR 

11.43 and 11.45, by any of the following 

methods:
