Airworthiness Directives; The Boeing 

Company Model 777–200, –300, and 

–300ER Series Airplanes 

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Supplemental notice of 

proposed rulemaking (NPRM); 

reopening of comment period. 

SUMMARY: We are revising an earlier 

proposed airworthiness directive (AD) 

for certain Model 777–200, –300, and 

–300ER series airplanes. The original 

NPRM would have required installing 

Teflon sleeving under the clamps of 

certain wire bundles routed along the 

fuel tank boundary structure, and cap 

sealing certain penetrating fasteners of 

the main and center fuel tanks. The 

original NPRM resulted from fuel 

system reviews conducted by the 

manufacturer. This action revises the 

original NPRM by adding airplanes and 

adding and removing certain 

requirements. We are proposing this 

supplemental NPRM to prevent 

electrical arcing on the fuel tank 

boundary structure or inside the fuel 

tanks, which could result in a fire or 

explosion. 

DATES: We must receive comments on 

this supplemental NPRM by July 13, 

2010. 

ADDRESSES: You may send comments by 

any of the following methods:

Discussion 

We issued a notice of proposed 

rulemaking (NPRM) (the ‘‘original 

NPRM’’) to amend 14 CFR part 39 to 

include an airworthiness directive (AD) 

that would apply to certain Boeing 

Model 777–200, –300, and –300ER 

series airplanes. That original NPRM 

was published in the Federal Register 

on January 29, 2007 (72 FR 3956). That 

original NPRM proposed to require 

installing Teflon sleeving under the 

clamps of the wire bundles routed along 

the fuel tank boundary structure, and 

cap sealing certain penetrating fasteners 

of the main and center fuel tanks. 

Actions Since Original NPRM Was 

Issued 

Since we issued the original NPRM, 

we have reviewed Boeing Alert Service 

Bulletin 777–57A0059, dated October 

30, 2008 (released after issuance of the 

original NPRM), which describes 

procedures for cap sealing certain 

fasteners in the center fuel tanks that 

were not sealed during production. We 

have changed Table 1 of the 

supplemental NPRM to refer to Boeing 

Alert Service Bulletin 777–57A0059, 

dated October 30, 2008, as the 

appropriate source of service 

information for certain actions. 

The original NPRM referred to Boeing 

Alert Service Bulletin 777–57A0050, 

dated January 26, 2006, as the 

appropriate source of service 

information for installing Teflon 

sleeving under the clamps of the power 

feeder wire bundles routed along certain 

fuel tank boundary structure and for cap 

sealing selected fasteners of the main 

and center fuel tanks. We have reviewed 

Boeing Service Bulletin 777–57A0050, 

Revision 2, dated May 14, 2009. 

Additional work is necessary for 

airplanes on which the original issue or 

Revision 1, dated August 2, 2007, of the 

service bulletin was done. The 

additional work includes the following 

actions, depending on airplane 

configuration: 

• Installing additional Teflon 

sleeving. 

• Cap sealing additional fasteners. 

We have changed Table 1 of this 

supplemental NPRM to include Boeing 

Service Bulletin 777–57A0050, Revision 

2, dated May 14, 2009, as the 

appropriate source of service 

information to use for accomplishing 

certain actions. We have also added a 

new paragraph (h) to this AD to give 

credit for actions done in accordance 

with Boeing Alert Service Bulletin 777– 

57A0050, dated January 26, 2006; or 

Revision 1, dated August 2, 2007; 

provided that the additional work 

specified in Boeing Service Bulletin 

777–57A0050, Revision 2, dated May 

14, 2009, is also done. 

We have also reviewed Boeing Alert 

Service Bulletin 777–57A0057, Revision 

1, dated August 2, 2007. The original 

NPRM referred to Boeing Alert Service 

Bulletin 777–57A0057, dated August 7, 

2006, as the appropriate source of 

service information for cap sealing 

certain fasteners in the center fuel tanks 

that were not sealed during production. 

Revision 1 removes unnecessary work 

instructions because Work Packages 2 

and 3 were completed prior to airplane 

delivery (for all affected airplanes). 

Revision 1 adds a general visual 

inspection to determine if certain 

fasteners are cap sealed and applying 

the cap seal to the fasteners that are not 

sealed. We have changed Table 1 of this 

supplemental NPRM to include Boeing 

Alert Service Bulletin 777–57A0057, 

Revision 1, dated August 2, 2007, as the 

appropriate source of service 

information to use for accomplishing 

certain actions. We have revised 

paragraph (g) of this supplemental 

NPRM (paragraph (f) of the original 

NPRM) to include the inspection and 

corrective action. We have also added a 

new paragraph (i) to this supplemental 

NPRM to give credit for actions done in 

accordance with Boeing Alert Service 

Bulletin 777–57A0057, dated August 7, 

2006. 

Comments 

We gave the public the opportunity to 

participate in developing this AD. We 

considered the comments received from 

the commenters. 

Request To Clarify Certain Language in 

Summary Section and Paragraph (g) 

Boeing asks that we clarify certain 

language in the Summary section and 

paragraph (f) of the original NPRM to 

read ‘‘. . . Teflon sleeving under the 

clamps of certain wire bundles routed 

along the fuel tank boundary structure.’’ 

Boeing states that the current language 

includes the phrase ‘‘the wire bundles,’’ 

which could lead operators to believe 

that all wire bundles will need sleeving, 

not just the wire bundles called out in 

the referenced service information. 

We agree that the subject language 

should be clarified. We have changed 

the Summary section and paragraph (g) 

of this supplemental NPRM accordingly. 

Request To Clarify Applicability 

Boeing asks that the applicability 

specified in Table 1 of the original 

NPRM be clarified by noting that Boeing 

Alert Service Bulletin 777–57A0051, 

dated May 15, 2006, does not apply to 

Model 777–300ER airplanes. Boeing 

states that the language in paragraph (c) 

of the original NPRM, which precedes 

Table 1, implies that all three service 

bulletins specified in the table apply to 

Model 777–300ER airplanes. 

We agree with the commenter for the 

reason provided; we have changed 

Table 1 of this supplemental NPRM, for 

clarification, to include the applicable 

airplane models in relation to the 

service information. 

Request To Add Maintenance 

Information 

Continental Airlines (CAL) asks that 

we add maintenance information to the 

original NPRM. CAL states that outside 

of the original NPRM, it is concerned 

that not enough attention is being given 

to ensure the changes in the referenced 

service information are preserved for the 

long-term operation of the Model 777 

airplane fleet. CAL notes that the 

original NPRM mandates a one-time 

change to implement the protection 

against ignition sources on affected 

airplanes; subsequent airplanes, 

including new deliveries entering 

service, already have the requirement 

incorporated in production. CAL states 

that, other than the referenced service 

information and some generic 

information in the Model 777 planning 

data, there is no published 

‘‘maintenance’’ document currently 

available to show each specific 

requirement as detailed in the 

referenced service information. CAL 

adds that information detailed by the 

service information must be made 

available in manuals that are routinely 

used by maintenance personnel. CAL 

notes that Boeing is reviewing different 

options for routine maintenance. 

We appreciate CALs concern and 

agree that the long-term operation of the 

Model 777 airplane fleet should be 

maintained. At the time the service 

information referenced by this 

supplemental NPRM was reviewed, the 

Instructions for Continued 

Airworthiness (ICAs) should have been 

updated to reflect and maintain the 

configuration in the supplemental 

NPRM throughout the life of each 


hsrobinson on DSK69SOYB1PROD with PROPOSALS-1
Federal Register / Vol. 75, No. 117 / Friday, June 18, 2010 / Proposed Rules 34665 

modified airplane. We did not recognize 

this deficiency at the time the service 

information was issued. However, 

Boeing is developing a revision to the 

ICAs that should be available to 

operators in the fall of 2010 for the 

required modifications. Operators will 

be notified when the revision is 

available. We may consider additional 

rulemaking when revised ICAs are 

issued to mandate their incorporation. 

We have not changed the supplemental 

NPRM in this regard. 

Request To Extend the Compliance 

Time 

The Air Transport Association (ATA) 

on behalf of its member Delta Air Lines 

Inc. (Delta) asks that we consider 

reviewing the compliance time to better 

align with industry standard tank entry 

intervals. Delta notes that the 

modifications will require entry into the 

main and center fuel tanks; the main 

fuel tanks are opened at 8-year intervals; 

and the center tank is opened at 4-year 

intervals. Delta states that the 60-month 

compliance time to accomplish 

corrective action will be acceptable for 

work required in the center tank, but 

will force main tank entry earlier than 

normally scheduled maintenance. 

We disagree with extending the 

proposed compliance time. The 

commenters did not provide any 

technical information to substantiate the 

assertion that extending the compliance 

time would not affect flight safety. In 

developing an appropriate compliance 

time, we considered the safety 

implications, parts availability, and 

normal maintenance schedules for 

timely accomplishment of the 

modification. Further, we arrived at the 

proposed compliance time with 

consideration of operator and 

manufacturer input. In consideration of 

these factors, we determined that the 

compliance time, as proposed, 

represents an appropriate interval in 

which the modification can be done in 

a timely manner within the fleet, while 

still maintaining an adequate level of 

safety. However, under the provisions of 

paragraph (j)(1) of this AD, we will 

consider requests for an adjustment to 

the compliance time if data are 

submitted to substantiate that such an 

adjustment would provide an acceptable 

level of safety. We have not changed the 

supplemental NPRM in this regard. 

Explanation of Changes to This 

Supplemental NPRM 

We have changed this supplemental 

NPRM to identify the legal name of the 

manufacturer as published in the most 

recent type certificate data sheet for the 

affected airplane models. 

Boeing Commercial Airplanes has 

received an Organization Designation 

Authorization (ODA), which replaces 

the previous designation as a Delegation 

Option Authorization (DOA) holder. We 

have revised paragraph (j)(3) of this AD 

to add delegation of authority to Boeing 

Commercial Airplanes ODA to approve 

an alternative method of compliance for 

any repair required by this AD. 

FAA’s Determination and Proposed 

Requirements of the Supplemental 

NPRM 

We are proposing this supplemental 

NPRM because we evaluated all 

pertinent information and determined 

an unsafe condition exists and is likely 

to exist or develop on other products of 

the same type design. Certain changes 

described above expand the scope of the 

original NPRM. As a result, we have 

determined that it is necessary to reopen 

the comment period to provide 

additional opportunity for the public to 

comment on this supplemental NPRM. 

Explanation of Change to Costs of 

Compliance 

Since issuance of the original NPRM, 

we have increased the labor rate used in 

the Costs of Compliance from $80 per 

work hour to $85 per work hour. The 

Costs of Compliance information, 

below, reflects this increase in the 

specified hourly labor rate. 

Costs of Compliance 

There are about 694 airplanes of the 

affected design in the worldwide fleet. 

This proposed AD would affect about 

129 airplanes of U.S. registry. We also 

estimate that it would take between 278 

and 358 work-hours per product to 

comply with the basic requirements of 

this proposed AD. Required parts would 

cost about $2,241 per product. The 

average labor rate is $85 per work-hour. 

Based on these figures, we estimate the 

cost of these proposed actions to the 

U.S. operators to be between $3,337,359 

and $4,214,559, or $25,871 and $32,671 

per product, depending on airplane 

configuration. 

Currently, there are no affected Group 

3 airplanes on the U.S. Register. 

However, if a Group 3 airplane is 

imported and placed on the U.S. 

Register in the future, the required 

actions would take about 480 work 

hours, at an average labor rate of $85 per 

work hour. Required parts would cost 

about $2,241 per product. Based on 

these figures, we estimate the cost of 

this proposed AD for Group 3 airplanes 

to be $43,041 per airplane. 

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. 

You can find our regulatory 

evaluation and the estimated costs of 

compliance in the AD Docket.
