Airworthiness Directives; The Boeing 

Company 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 

The. This proposed AD was prompted 

by a report that during a test of the 

oxygen system, an operator found that 

the passenger oxygen masks did not 

properly flow oxygen, and that a loud 

noise occurred in the overhead area, 

which was caused by the flex line 

separating from the hard line due to a 

missing clamshell coupler. This 

proposed AD would require, for certain 

airplanes, performing a detailed 

inspection of certain areas of the 

airplane oxygen system to ensure 

clamshell couplers are installed and 

fully latched, and corrective actions if 

necessary. For all airplanes, this 

proposed AD would require performing 

and meeting the requirements of the low 

pressure leak test. We are proposing this 

AD to prevent the oxygen system flex 

line from separating from the hard line, 

which could cause an oxygen leak and 

a drop in the oxygen system pressure, 

resulting in improper flow of oxygen 

through the passenger masks and injury 

to passengers if emergency oxygen is 

needed. 

DATES: We must receive comments on 

this proposed AD by October 26, 2012. 

ADDRESSES: You may send comments, 

using the procedures found in 14 CFR 

11.43 and 11.45, by any of the following 

methods:

SUPPLEMENTARY INFORMATION: 

Comments Invited 

We invite you to send any written 

relevant data, views, or arguments about 

this proposal. Send your comments to 

an address listed under the ADDRESSES

section. Include ‘‘Docket No. FAA– 

2012–0932; Directorate Identifier 2012– 

NM–014–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 a report that during 

a test of the oxygen system, an operator 

found that the passenger oxygen masks 

did not properly flow oxygen and that 

a loud noise occurred in the overhead 

area, which was caused by the flex line 

separating from the hard line due to a 

missing clamshell coupler. This 

condition, if not corrected, could result 

in the oxygen system flex line from 

separating from the hard line, which 

could cause an oxygen leak and a drop 

in the oxygen system pressure, resulting 

in improper flow of oxygen through the 

passenger masks and injury to 

passengers if emergency oxygen is 

needed. 

Relevant Service Information 

We reviewed Boeing Special 

Attention Service Bulletin 777–35– 

0024, dated September 1, 2011. The 

service information describes, for 

certain airplanes, procedures for a 

detailed inspection of certain areas of 

the airplane oxygen system to ensure 

clamshell couplers are installed and 

fully latched, corrective actions if 

necessary; and, for all airplanes, 

performing and meeting the 

requirements of the low pressure leak 

test. The corrective action is installing 

or correctly latching the clamshell 

coupler. 

FAA’s Determination 

We are proposing this AD because we 

evaluated all the relevant information 

and determined the unsafe condition 

described previously is likely to exist or 

develop in other products of the same 

type design. 

Proposed AD Requirements 

This proposed AD would require 

accomplishing the actions specified in 

the service information described 

previously, except as discussed under 

‘‘Differences Between the Proposed AD 

and the Service Information.’’ 

Differences Between the Proposed AD 

and the Service Information 

Boeing Special Attention Service 

Bulletin 777–35–0024, dated September 

1, 2011, describes procedures for 

inspecting to determine if a clamshell 

coupler is installed, but it does not 

provide a corrective action if a 

clamshell coupler is not installed. This 

proposed AD would require installing a 

clamshell coupler if any clamshell 

coupler is not installed. 

Costs of Compliance 

We estimate that this proposed AD 

affects 6 airplanes of U.S. registry. 

We estimate the following costs to 

comply with this proposed AD: 

ESTIMATED COSTS

Action Labor cost Parts cost Cost per 

product 

Cost on U.S. 

operators 

Detailed inspection and leak test .................... 26 work-hours × $85 per hour = $2,210 ........ $0 $2,210 $13,260 

We have received no definitive data 

that would enable us to provide cost 

estimates for the on-condition actions 

specified in this proposed AD. 

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), 

(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.

The Proposed Amendment 

Accordingly, under the authority 

delegated to me by the Administrator, 

the FAA proposes to amend 14 CFR part 

39 as follows:
