Airworthiness Directives; The Boeing 

Company Airplanes 

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Final rule. 

SUMMARY: We are adopting a new 

airworthiness directive (AD) for certain 

The Boeing Company Model 767–300 

series airplanes. This AD was prompted 

by a report that certain airplanes might 

not have reinforcement straps installed 

on the center overhead stowage bins in 

the passenger compartment, and some 

installed reinforcement straps might not 

have been bonded. For certain airplanes, 

this AD requires performing an 

inspection of reinforcement straps to 

ensure they are correctly bonded to the 

center overhead stowage bins, and 

bonding the reinforcement straps to the 

center overhead stowage bins if 

necessary. For certain airplanes, this AD 

requires installing reinforcement straps 

on the center overhead stowage bins. 

We are issuing this AD to prevent 

missing or incorrectly bonded 

reinforcement straps, which could result 

in the center overhead stowage bins 

breaking loose at forward load levels 

less than 9g during an emergency 

landing, causing injury to passengers 

and delaying emergency evacuation. 

DATES: This AD is effective June 5, 2013. 

The Director of the Federal Register 

approved the incorporation by reference 

of a certain publication listed in the AD 

as of June 5, 2013.

SUPPLEMENTARY INFORMATION: 


wreier-aviles on DSK5TPTVN1PROD with RULES
Federal Register / Vol. 78, No. 84 / Wednesday, May 1, 2013 / Rules and Regulations 25375 

Discussion 

We issued a notice of proposed 

rulemaking (NPRM) to amend 14 CFR 

part 39 to include an AD that would 

apply to the specified products. That 

NPRM published in the Federal 

Register on October 16, 2012 (77 FR 

63266). That NPRM proposed to require, 

for certain airplanes, performing an 

inspection of reinforcement straps to 

ensure they are correctly bonded to the 

center overhead stowage bins, and 

bonding the reinforcement straps to the 

center overhead stowage bins if 

necessary. For certain airplanes, that 

NPRM also proposed installing 

reinforcement straps on the center 

overhead stowage bins. 

Comments 

We gave the public the opportunity to 

participate in developing this AD. The 

following presents the comments 

received on the proposal (77 FR 63266, 

October 16, 2012) and the FAA’s 

response to each comment. 

Aviation Partners Boeing stated that 

the installation of winglets per 

supplemental type certificate (STC) 

ST01920SE (http://rgl.faa.gov/ 

Regulatory_and_Guidance_Library/ 

rgstc.nsf/0/ 

59027f43b9a7486e86257b1d006591ee/ 

$FILE/ST01920SE.pdf) does not affect 

the accomplishment of the 

manufacturer’s service instructions. 

Request To Remove Reference to ‘‘Inflight Turbulence’’ 

Boeing requested that the potential 

injury statement that appears in the 

Summary paragraph, Discussion 

paragraph, and paragraph (e), ‘‘Unsafe 

Condition,’’ of the NPRM (77 FR 63266, 

October 16, 2012) be revised to remove 

the reference to in-flight turbulence. 

Boeing suggested that the potential 

injury statement should specify the 

requirements associated with section 

25.561(b)(3)(ii) (‘‘9.0g Forward loads’’) 

of the Federal Aviation Regulations (14 

CFR 25.561). Boeing stated that Boeing 

Special Attention Service Bulletin 767– 

25–0520, dated February 8, 2012, and 

associated certification data, refer only 

to 9.0g forward loads and not in-flight 

loads. 

Based on the reasons provided by the 

commenter, we agree to revise the 

potential injury statement by deleting 

the reference to ‘‘in-flight turbulence’’ 

and including a reference to 9g forward 

loads. The potential injury statement in 

this AD states ‘‘We are issuing this AD 

to prevent missing or incorrectly 

bonded reinforcement straps, which 

could result in the center overhead 

stowage bins breaking loose at forward 

load levels less than 9g during an 

emergency landing, causing injury to 

passengers and delaying emergency 

evacuation.’’ 

The revised potential injury statement 

appears in the Summary paragraph and 

paragraph (e) of this AD. The potential 

injury statement is not restated in the 

Discussion paragraph of this AD, so no 

change is needed to that paragraph. 

Request To Clarify Precipatory Event 

Boeing requested that paragraph (e), 

‘‘Unsafe Condition,’’ in the NPRM (77 

FR 63266, October 16, 2012) be revised 

so the first sentence states that ‘‘certain 

airplanes (1) may not have 

reinforcement straps installed and (2) 

may not have been bonded at some 

center overhead stowage bin locations.’’ 

The suggested text is from Boeing 

Special Attention Service Bulletin 767– 

25–0520, dated February 8, 2012. 

Boeing noted that the NPRM does not 

address condition (1) and is not 

consistent with condition (2). 

We agree with Boeing’s request to 

revise the wording that describes what 

prompted this AD. Boeing’s suggested 

changes clarify the conditions that 

operators may encounter when 

complying with the actions required by 

this AD. The revised statement appears 

in the Summary paragraph and 

paragraph (e) of this AD. 

Request To Revise the ‘‘Relevant 

Service Information’’ Paragraph 

Boeing requested that the text in the 

‘‘Relevant Service Information’’ 

paragraph of the NPRM (77 FR 63266, 

October 16, 2012) be changed so the 

language within the NPRM and the 

language between the NPRM and Boeing 

Special Attention Service Bulletin 767– 

25–0520, dated February 8, 2012, is 

consistent. Boeing suggested that in the 

second sentence of that paragraph, 

beginning with ‘‘For certain airplanes, 

this service bulletin describes 

procedures for general visual and 

detailed inspection of the existing 

reinforcement straps installed on the 

center overhead storage bins . . ..’’ 

‘‘storage’’ be changed to ‘‘stowage.’’ 

Boeing also suggested that the third 

sentence of that paragraph, beginning 

with ‘‘For airplanes on which the straps 

are incorrectly bonded . . . .’’ be revised 

to delete ‘‘are incorrectly bonded’’ and 

insert ‘‘may not be bonded or were 

inadvertently missed.’’ 

Boeing also requested that the last 

sentence in the ‘‘Relevant Service 

Information’’ paragraph be removed and 

the sentence prior to that one, beginning 

with ‘‘For airplanes on which the straps 

are incorrectly bonded, this service 

bulletin describes procedures for 

bonding the reinforcement straps 

. . . .’’ be revised to read, ‘‘. . . bonding 

and installation of the reinforcement 

straps . . . .’’ Boeing stated that these 

changes would provide clarity to the 

operators. 

We agree that the suggestions made by 

the commenter provide a more accurate 

description of the information in Boeing 

Special Attention Service Bulletin 767– 

25–0520, dated February 8, 2012; 

however, the ‘‘Relevant Service 

Information’’ paragraph is not restated 

in this AD, so no change has been made 

to this AD in this regard. 

Explanation of Change Made to This 

AD 

We have added a new paragraph 

(h)(3) to this final rule to allow 

delegation of repairs to the Boeing 

Commercial Airplanes Organization 

Designation Authorization (ODA). 

Conclusion 

We reviewed the relevant data, 

considered the comments received, and 

determined that air safety and the 

public interest require adopting the AD 

with the changes described previously– 

and minor editorial changes. We have 

determined that these minor changes: 

• Are consistent with the intent that 

was proposed in the NPRM (77 FR 

63266, October 16, 2012) for correcting 

the unsafe condition; and 

• Do not add any additional burden 

upon the public than was already 

proposed in the NPRM (77 FR 63266, 

October 16, 2012). 

We also determined that these 

changes will not increase the economic 

burden on any operator or increase the 

scope of the AD. 

Costs of Compliance 

We estimate that this AD affects 4 

airplanes of U.S. registry. 

We estimate the following costs to 

comply with this AD:

We estimate the following costs to do 

any necessary repairs that would be 

required based on the results of the 

inspection. We have no way of 

determining the number of aircraft that 

might need this repair:

$0 Between $595 and $1,020. 

According to the manufacturer, 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.

SUMMARY: We are adopting a new 

airworthiness directive (AD) for certain 

The Boeing Company Model 737–600, 

–700, –700C, –800, –900 and –900ER 

series airplanes. This AD was prompted 

by a report of leaking fuel from the wing 

leading edge area at the inboard end of 

the number 5 leading edge slat. This AD 

requires modifying the fluid drain path 

in the wing leading edge area, forward 

of the wing front spar, and doing all 

applicable related investigative and 

corrective actions; and installing new 

seal disks on the latches in the fuel 

shutoff valve access door. We are 

issuing this AD to prevent flammable 

fluids from accumulating in the wing 

leading edge, and draining inboard and 

onto the engine exhaust nozzle, which 

could result in a fire. 

DATES: This AD is effective June 5, 2013. 

The Director of the Federal Register

SUPPLEMENTARY INFORMATION:

Discussion 

We issued a supplemental notice of 

proposed rulemaking (SNPRM) to 

amend 14 CFR part 39 to include an 

airworthiness directive (AD) that would 

apply to the specified products. That 

SNPRM published in the Federal 

Register on March 16, 2012 (77 FR 

15638). The original NPRM (74 FR 

15683, April 7, 2009) proposed to 

require modifying the fluid drain path 

in the wing leading edge area, forward 

of the wing front spar and doing all 

applicable related investigative and 

corrective actions. The SNPRM 

proposed to revise that NPRM by 

including installing new seal disks on 

the latches in the fuel shutoff valve 

access door as part of the modification 

and by specifying that certain 

inspections are detailed inspections. 

The SNPRM also proposed to revise the 

applicability to include additional 

airplanes.

Service Bulletin 737–57–1293, Revision
