ACTION: Final rule. 

SUMMARY: We are adopting a new 

airworthiness directive (AD) for certain 

The Boeing Company Model 777–200, 

–200LR, –300, –300ER, and 777F series 

airplanes. This AD was prompted by a 

report indicating that a fire originated 

near the first officer’s area, which 

caused extensive damage to the flight 

deck. This AD requires replacing the 

low-pressure oxygen hoses with nonconductive low-pressure oxygen hoses 

in the flight compartment. We are 

issuing this AD to prevent electrical 

current from passing through the lowpressure oxygen hose internal anticollapse spring, which can cause the 

low-pressure oxygen hose to melt or 

burn, and a consequent oxygen-fed fire 

in the flight compartment. 

DATES: This AD is effective August 16, 

2012. 

The Director of the Federal Register 

approved the incorporation by reference 

of certain publications listed in the AD 

as of August 16, 2012.

pmangrum on DSK3VPTVN1PROD with RULES
41046 Federal Register / Vol. 77, No. 134 / Thursday, July 12, 2012 / Rules and Regulations 

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 February 8, 2012 (77 FR 

6518). That NPRM proposed to require 

replacing the low-pressure oxygen hoses 

with non-conductive low-pressure 

oxygen hoses in the flight compartment. 

Relevant Service Information 

Since we issued the NPRM (77 FR 

6518, February 8, 2012), Boeing has 

issued Alert Service Bulletin 777– 

35A0027, Revision 1, dated April 19, 

2012. This service information was 

issued to remove airplanes from the 

effectivity that have had certain changes 

incorporated in production, update 

warranty information, and material 

price information. No additional work is 

necessary for airplanes changed in 

accordance with Boeing Alert Service 

Bulletin 777–35A0027, dated December 

15, 2011. We have changed the final 

rule to reference Boeing Alert Service 

Bulletin 777–35A0027, Revision 1, 

dated April 19, 2012. Additionally, we 

have updated the Costs of Compliance 

section of the final rule regarding the 

parts cost and warranty information. 

Comments 

We gave the public the opportunity to 

participate in developing this AD. The 

following presents the comments 

received on the proposal (77 FR 6518, 

February 8, 2012) and the FAA’s 

response to each comment. 

Support for the NPRM (77 FR 6518, 

February 8, 2012) 

The Air Line Pilots Association 

(ALPA) stated it supports the NPRM (77 

FR 6518, February 8, 2012). 

Request To Shorten Compliance Time 

The ALPA requested we shorten the 

compliance time for the replacement of 

the oxygen hoses from 18 months to 12 

months. The commenter based this 

request on the impact that an oxygen fed 

fire on the flight deck would have on 

flight safety. 

We disagree. In developing the 

proposed compliance time, we 

considered the safety implications, parts 

availability, and normal maintenance 

schedules for the timely 

accomplishment of replacement of the 

oxygen hoses. Further, the proposed 

compliance time is in keeping with the 

manufacturers’ recommended 

compliance time. In consideration of all 

these factors, operators are always 

permitted to accomplish the 

requirements of an AD at a time earlier 

than the specified compliance time. If 

additional data are presented that would 

justify a shorter compliance time, we 

may consider further rulemaking on this 

issue. We have not changed the AD in 

this regard. 

Request To Increase Compliance Time 

United Airlines requested we increase 

the compliance time for the replacement 

of the oxygen hoses from 18 months to 

24 months. The commenter stated that 

based on parts availability and its 

normal maintenance schedule, it 

believes that 24 months would be an 

appropriate interval for the timely 

accomplishment of the actions while 

maintaining an adequate level of safety. 

We disagree with increasing the 

compliance time. As stated previously, 

in developing the proposed compliance 

time, we considered the safety 

implications, parts availability, and 

normal maintenance schedules for a 

timely accomplishment of replacement 

of the oxygen hoses. Further, the 

proposed compliance time is in keeping 

with the manufacturers’ recommended 

compliance time. However, under the 

provisions of paragraph (i) of the final 

rule, we may approve requests for 

adjustments 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 AD in this regard. 

Request To Add Applicability Language 

Boeing requested that we add 

language to paragraph (h) of the NPRM 

(77 FR 6518, February 8, 2012), stating 

that this paragraph applies only to any 

airplane ‘‘affected by this AD.’’ 

We do not agree with the commenter’s 

request. The applicability statement in 

all AD actions lists all airplanes affected 

by that AD. All of the requirements 

stated in an AD are applicable only to 

the airplanes listed in the applicability. 

We find no justification for making the 

requested change. We have not changed 

the AD in this regard. 

Request for Clarification of Parts 

Installation Requirement 

American Airlines (American) 

requested clarification of the 

requirement in paragraph (h) of the 

NPRM (77 FR 6518, February 8, 2012) 

that prohibits installing certain oxygen 

hoses after the effective date of the AD. 

American stated that the compliance 

time of paragraph (h) of the NPRM is 

prior to the compliance date of the lowpressure oxygen hose removal, and if a 

maintenance procedure is accomplished 

which would require the removal of the 

low-pressure oxygen hose, the same 

low-pressure oxygen hose cannot be reinstalled. 

We agree to clarify the requirement. 

Once we have determined that an 

unsafe condition exists, we generally 

specify not to allow that condition to be 

introduced into the fleet. Although the 

word ‘‘install’’ is generally considered 

to be broader than the word ‘‘replace,’’ 

for this AD operators can interpret it as 

meaning ‘‘replace’’ while remaining 

within the intent of the ‘‘Parts 

Installation’’ paragraph (paragraph (h) of 

this AD). By simply reinstalling a part 

removed during maintenance, the 

operator is not ‘‘installing’’ a different 

part. Therefore, removing a part to gain 

access and then reinstalling that same 

part for other maintenance activities not 

associated with the AD is acceptable. 

We have not changed the AD in this 

regard. 

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 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 169 

airplanes of U.S. registry. 

We estimate the following costs to 

comply with this AD: 

ESTIMATED COSTS

Action Labor cost Parts cost Cost per 

product 

Cost on U.S. 

operators 

Replacement ................................................... 18 work-hours × $85 per hour = $1,530 ........ $1,066 $2,596 $438,724 


pmangrum on DSK3VPTVN1PROD with RULES
Federal Register / Vol. 77, No. 134 / Thursday, July 12, 2012 / Rules and Regulations 41047 

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.
