–300, and –300ER Series Airplanes 

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Notice of proposed rulemaking 

(NPRM). 

SUMMARY: We propose to adopt a new 

airworthiness directive (AD) for certain 

Model 777–200, –200LR, –300, and 

–300ER series airplanes. This proposed 

AD would require removing and 

repairing the sealant at the four lower 

corners of the wing center section and 

the four lower t-chord segment gaps on 

each side of the wing center section. 

This proposed AD results from reports 

of fuel leakage from the center tank. We 

are proposing this AD to detect and 

correct improperly applied sealant, 

which could result in the disbonding 

and displacing of sealant, and

consequent fuel leaks. On the ground, 

uncontained fuel leakage could result in 

pooling, and pooling combined with an 

ignition source could result in a fire.

SUPPLEMENTARY INFORMATION: 

Comments Invited 

We invite you to send any written 

relevant data, views, or arguments about 

this proposed AD. Send your comments 

to an address listed under the 

ADDRESSES section. Include ‘‘Docket No. 

FAA–2010–0376; Directorate Identifier 

2009–NM–267–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 have received reports that 7 

operators have reported 9 cases of fuel 

leakage from the center tank on 9 

airplanes. These airplanes had 

accumulated approximately 10 to 

10,000 flight hours, 5 to 2,000 flight 

cycles, and 1 to 26 months in service. 

The leaks were found at the two aft 

lower corners of the wing center section 

and one leak was found at one of the 

four gaps between the lower t-chord 

segments on each side of the wing 

center section. The forward lower 

corners and the remaining gaps between 

the t-chord segments are also believed to 

be susceptible to fuel leakage. The leaks 

are believed to be the result of 

improperly applied sealant during 

production. This condition, if not 

detected and corrected, could result in 

failing by the disbonding and displacing 

of sealant, which can result in fuel leaks 

of up to 10 gallons per minute. During 

flight, the fuel would leak into areas that 

have been designed to accommodate 

fuel leakage, but on the ground, if the 

fuel leakage is not contained, it could 

result in pooling. This pooling 

combined with an ignition source could 

result in a fire. 

Relevant Service Information 

We have reviewed Boeing Special 

Attention Service Bulletin 777–57– 

0063, Revision 1, dated May 14, 2009. 

The service bulletin describes 

procedures for removing and repairing 

the sealant at the four lower corners of 

the wing center section and the four 

lower t-chord segment gaps on each side 

of the wing center section. 

FAA’s Determination and Requirements 

of This Proposed AD 

We are proposing this AD because we 

evaluated all 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 would 

require accomplishing the actions 

specified in the service information 

described previously. 

Costs of Compliance 

We estimate that this proposed AD 

would affect 8 airplanes of U.S. registry. 

We also estimate that it would take 

about 10 work-hours per product to 

comply with this proposed AD. The 

average labor rate is $85 per work-hour. 

Based on these figures, we estimate the 

cost of this proposed AD to the U.S. 

operators to be $6,800, or $850 per 

product. 

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), and 

3. 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.
