AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Final rule. 

SUMMARY: We are adopting a new 

airworthiness directive (AD) for the 

products listed above. This AD requires 

installing foreign object debris (FOD) 

rubber shields over the primary and 

secondary external power connectors for 

certain airplanes, and wrapping silicone 

tape around the hydraulic tube for 

certain other airplanes. This AD was 

prompted by a report of a fire in the 

main equipment center due to failure of 

an external power connector, which 

WREIER-aviles on DSK7SPTVN1PROD with RULES

63164 Federal Register / Vol. 76, No. 197 / Wednesday, October 12, 2011 / Rules and Regulations 

caused high-temperature arcing and 

subsequent splatter of molten copper on 

an adjacent hydraulic tube, creating a 

hole in the tube and spraying hydraulic 

fluid into the power connector, resulting 

in a fire. In addition there were several 

reports of overheating or arcing of 

external power connectors, and one 

report of a fire due to arcing caused by 

FOD. We are issuing this AD to prevent 

FOD from entering the primary and 

secondary external power connectors, 

which could result in overheating or 

arcing and consequent fire in the main 

equipment center. 

DATES: This AD is effective November 

16, 2011. 

The Director of the Federal Register 

approved the incorporation by reference 

of certain publications listed in the AD 

as of November 16, 2011.

SUPPLEMENTARY INFORMATION: 

Discussion 

We issued a notice of proposed 

rulemaking (NPRM) to amend 14 CFR 

part 39 to include an airworthiness 

directive (AD) that would apply to the 

specified products. That NPRM 

published in the Federal Register on 

January 18, 2011 (76 FR 2846). That 

NPRM proposed to require installing 

foreign object debris (FOD) rubber 

shields over the primary and secondary 

external power connectors for certain 

airplanes, and wrapping fire-resistant 

silicone tape around the hydraulic tube 

for certain other airplanes. 

Comments 

We gave the public the opportunity to 

participate in developing this AD. The 

following presents the comments 

received on the proposal and the FAA’s 

response to each comment. 

Support for the NPRM 

American Airlines has accomplished 

the modifications on the majority of its 

fleet, and has no objection to the actions 

and compliance times in the NPRM (76 

FR 2846, January 18, 2011). The 

National Transportation Safety Board 

supports the NPRM. 

Request To Use Latest Production 

Hydraulic Tube 

Japan Airlines (JAL), Continental 

Airlines, and All Nippon Airways 

(ANA) asked that operators be allowed 

to use the latest production hydraulic 

tube having part number (P/N) 

272W4190–192, which already has the 

silicone tape pre-wrapped, in lieu of 

modifying the existing hydraulic tube 

assembly by installing the silicone tape 

in accordance with Boeing Special 

Attention Service Bulletin 777–29– 

0032, dated August 9, 2007. JAL also 

noted a concern about procuring the 

hydraulic tube. 

We do not agree with the request to 

use the latest production hydraulic tube 

as an acceptable alternative to installing 

the silicone tape. Based on the latest 

information received from Boeing 

engineering, the following applies to 

any possible hydraulic tube 

replacement: Any hydraulic tube having 

P/N 272W4190–192 (as specified in 

Boeing Special Attention Service 

Bulletin 777–29–0032, dated August 9, 

2007), cannot be a direct replacement 

for the existing part. Hydraulic tubes 

having P/Ns 272W4190–93, –168, and 

–192 for production installation require 

the use of permaswage fittings on either 

side of the tube. Removal of the tube for 

its replacement requires that the tube be 

physically cut past the permaswage 

fitting, thus making it longer than the 

original production part. We have made 

no change to the AD in this regard. 

Request To Include Instructions for 

Continued Airworthiness 

Continental and ANA also noted that 

the service information does not contain 

proper instructions for continued 

airworthiness (ICAs) to install the tape 

on the new line, or inclusion of the 

equivalent production part number in 

the Boeing 777 illustrated parts catalog 

(IPC). Continental added that a pre- and 

post-service bulletin configuration 

should be included to provide 

instructions to use a newer part or to 

accomplish the actions specified in the 

service information again. 

We acknowledge the commenters’ 

concern, but we do not agree. The 

Boeing ICAs do include a statement 

indicating that the production tubes are 

reworked by using the procedures in 

Boeing Special Attention Service 

Bulletin 777–29–0032, dated August 9, 

2007. Since there is not direct 

replacement with a production tube, we 

are working with Boeing to identify 

additional information necessary in 

support of replacing the hydraulic tube. 

We have made no change to the AD in 

this regard. 

Request To Include Information Notices 

United Airlines asked that we revise 

the NPRM (76 FR 2846, January 18, 

2011) to refer to Boeing Service Bulletin 

Information Notices 777–29–0032 IN 01, 

dated November 29, 2007, and 777–29– 

0032 IN 02, dated December 11, 2008, 

which include clarifications to the 

Accomplishment Instructions of Boeing 

Special Attention Service Bulletin 777– 

29–0032, dated August 9, 2007. 

We acknowledge that these 

information notices may be useful to 

operators to clarify certain instructions 

specified in Boeing Special Attention 

Service Bulletin 777–29–0032, dated 

August 9, 2007. However, Boeing has 

provided these notices to operators. We 

do not reference information notices in 

ADs because those documents are not 

FAA-reviewed. In addition, the 

information notices do not contain 

technical information and are not 

necessary to accomplish the actions 

required by the AD. We have made no 

change to the AD in this regard. 

Request To Change the Applicability 

Boeing requested that the 

applicability section in the NPRM (76 

FR 2846, January 18, 2011) be changed. 

Boeing stated that the applicability 

should be limited to the airplanes 

identified in the referenced service 

information, which include only those 

airplanes on which the modifications 

required by the AD have not been 

accomplished in production. 

WREIER-aviles on DSK7SPTVN1PROD with RULES

Federal Register / Vol. 76, No. 197 / Wednesday, October 12, 2011 / Rules and Regulations 63165 

We agree with the commenter for the 

reason provided and have limited the 

applicability section in this AD 

accordingly, in lieu of specifying ‘‘all’’ 

airplanes of the affected model. 

Request To Clarify Tape Qualities 

Boeing asked that we delete the term 

‘‘fire-resistant,’’ which describes 

‘‘silicone tape,’’ as specified in the 

Summary section, Relevant Service 

Information section, and paragraph 

(g)(2) of the NPRM (76 FR 2846, January 

18, 2011). Boeing stated that the product 

data sheet identifies the tape as ‘‘high 

temperature arc- and track-resistant 

tape,’’ but not ‘‘fire-resistant.’’ 

We agree with the commenter for the 

reason provided. However, the term 

‘‘fire-resistant’’ was used in the NPRM 

(76 FR 2846, January 18, 2011) because 

it is specified as such in the referenced 

service information. We have removed it 

from the Summary section and 

paragraph (g)(2) of this AD. The 

Relevant Service Information section of 

the preamble does not reappear in the 

final rule. 

Request To Clarify Terminology of Tape 

Dimensions 

Boeing asked that we change the 

language in the ‘‘Exception to Service 

Information’’ section in paragraph (h) of 

the NPRM (76 FR 2846, January 18, 

2011) as follows: ‘‘Figure 1 of the 

Accomplishment Instructions of Boeing 

Special Attention Service Bulletin 777– 

29–0032, dated August 9, 2007, does not 

identify the units of the dimensions of 

the silicone tape installed on the 

hydraulic tube; those dimensions are 

identified in inches.’’ Boeing noted that 

the dimensions of the tape are 

identified, but the units of the 

dimensions are missing. Boeing added 

that, although the tape can be used as 

‘‘electrical’’ tape, for this application it 

is more appropriate to identify it as 

‘‘silicone’’ tape. 

We agree with the commenter for the 

reasons provided. The word ‘‘electrical’’ 

was used in the NPRM (76 FR 2846, 

January 18, 2011) because it is specified 

as such in the referenced service 

information. We have changed 

paragraph (h) of this AD to reiterate the 

commenter’s suggested language. 

Request To Provide Additional Credit 

Boeing asked that the service 

information specified in paragraph (i) of 

the NPRM (76 FR 2846, January 18, 

2011) under ‘‘Credit for Actions 

Accomplished in Accordance with 

Previous Service Information’’ be 

changed to include Boeing Special 

Attention Service Bulletin 777–29– 

0032, dated August 9, 2007 (referred to 

in the NPRM as the service information 

to use for installing the silicone tape). 

Boeing stated that the modification 

accomplished by this service bulletin 

before the effective date of the AD is 

identical to the modification 

accomplished by this service bulletin 

after the effective date of the AD. 

We do not agree that the subject 

service bulletin should be added to 

paragraph (i) of this AD. Operators are 

already given credit for previously 

accomplished actions as allowed by the 

phrase in paragraph (f) of this AD which 

states the following: ‘‘Comply with this 

AD within the compliance times 

specified, unless already done.’’ We 

have made no change to the AD in this 

regard. 

Request To Exclude Certain Proposed 

Actions 

Delta Airlines asked that Boeing 

Special Attention Service Bulletin 777– 

29–0032, dated August 9, 2007, be 

excluded from the NPRM (76 FR 2846, 

January 18, 2011). Delta stated that since 

the root cause of the external power 

connector fires and overheating was 

related to foreign object debris (FOD) 

shorting out the external power 

connector inside the airplane, once the 

FOD shields are installed per Boeing 

Service Bulletin 777–24–0102, Revision 

1, dated June 17, 2010, the protective 

tape identified in Boeing Special 

Attention Service Bulletin 777–29– 

0032, dated August 9, 2007, serves no 

purpose. Delta added that if damage to 

the hydraulic tubing is still a concern 

even after accomplishment of this 

service bulletin, a routing change to the 

hydraulic tubing would be a better 

solution to protecting the tubing from a 

fire/overheat condition. Delta noted that 

the tape being installed is not fireproof, 

only fire-resistant. Delta also stated that 

the instructions for installing the tape 

specified in Boeing Special Attention 

Service Bulletin 777–29–0032, dated 

August 9, 2007, would be difficult to 

comply with. Subsequent inspections of 

the tape installation to ensure 

compliance with the NPRM would also 

be difficult when judging the overlap 

and number of tape wraps, since the 

tape installation is based on the amount 

of stretch and a percentage of overlap. 

We do not agree to remove Boeing 

Special Attention Service Bulletin 777– 

29–0032, dated August 9, 2007, from 

this AD. Installation of the FOD shields 

is not the only action necessary to 

address the identified unsafe condition. 

FOD shields alone do not resolve the 

potential for overheating and arcing of 

the electrical connectors. Based on our 

evaluation, we have determined that the 

connector design, lack of proper 

connector maintenance actions, and the 

proximity of the hydraulic tubing to the 

connectors can result in a fire; therefore, 

accomplishing the actions required by 

this AD will minimize the threat of fire 

on the airplane. 

Additionally, although the silicone 

tape is not fireproof, installing the tape 

provides an acceptable level of 

protection to the hydraulic tubing in the 

event of overheating or arcing of the 

connectors. The procedures for 

installing the tape are not difficult for 

compliance and include easy access and 

liberal application of the tape; several 

operators have already done this 

modification and did not encounter any 

problems. Further, it is the 

responsibility of operators to maintain 

the AD-mandated configuration, and 

this can be done using the procedures 

specified in Boeing Special Attention 

Service Bulletin 777–29–0032, dated 

August 9, 2007. In light of these factors, 

we have made no change to the AD. 

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. 

We have determined that these changes 

will neither increase the economic 

burden on any operator nor increase the 

scope of the AD. 

Costs of Compliance 

We estimate that this AD will affect 

126 airplanes of U.S. registry. We

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.

adjacent hydraulic tube, creating a hole in 

the tube and spraying hydraulic fluid into the 

power connector, resulting in a fire. In 

addition there were several reports of 

overheating or arcing of external power 

connectors, and one report of a fire due to 

arcing caused by foreign object debris (FOD). 

We are issuing this AD to prevent FOD from 

entering the primary and secondary external 

power connectors, which could result in 

overheating or arcing and consequent fire in 

the main equipment center.

2009; Revision E, dated May 12, 2010; 

or Revision F, dated July 6, 2010. This 

AD was prompted by reports of damage 

around the VCS compressor mounting 

areas found during maintenance 

inspections. This AD requires 

deactivation of the VCS, removal of the 

compressor and bracket, and revision to 

the airplane weight and balance. We are 

issuing this AD to correct the unsafe 

condition on these products. 

DATES: This AD is effective November 

16, 2011. 

The Director of the Federal Register

SUPPLEMENTARY INFORMATION: 

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 June 28, 2011 (76 FR 37684). 

That NPRM proposed to require removal 

of the VCS mount, which could result 

in the air conditioner compressor 

disconnecting in the engine 

compartment. This condition could 

result in engine stoppage or additional 

damage to the engine. 

Comments 

We gave the public the opportunity to 

participate in developing this AD. We 

received no comments on the NPRM (76 

FR 37684, June 28, 2011) or on the 

determination of the cost to the public. 

Conclusion 

We reviewed the relevant data and 

determined that air safety and the 

public interest require adopting the AD 

as proposed except for minor editorial 

changes and the addition of an optional 

terminating action after the compressor 

is removed which will allow for the 

reinstallation and reactivation of the air 

conditioning system. We have 

determined that these minor changes: 

• Are consistent with the intent that 

was proposed in the NPRM (76 FR 

37684, June 28, 2011) for correcting the 

unsafe condition; and 

• Do not add any additional burden 

upon the public than was already 

proposed in the NPRM. 

Costs of Compliance 

We estimate that this AD affects 11 

airplanes of U.S. registry. 

We estimate the following costs to 

comply with this AD:
