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 Boeing Company Model 777–200, 

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

airplanes. This proposed 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 proposed AD 

would require replacing the lowpressure oxygen hoses with nonconductive low-pressure oxygen hoses 

in the flight compartment. We are 

proposing 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: We must receive comments on 

this proposed AD by March 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– 

2012–0104 2011–NM–279–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 received a report indicating that a 

fire originated near the first officer’s 

area, which caused extensive damage to 

the flight deck. The cause of this 

incident is unknown. One scenario of 

the causes being considered is that an 

electrical fault or short circuit resulted 

in electrical heating of the low-pressure 

oxygen hoses in the flight crew oxygen 

system. This condition, if not corrected, 

could cause electrical current to pass 

through the low-pressure oxygen hose 

internal anti-collapse spring, which can 

cause the low-pressure oxygen hose to 

melt or burn, and a consequent oxygenfed fire in the flight compartment. 

Relevant Service Information 

We reviewed Boeing Alert Service 

Bulletin 777–35A0027, dated December 

15, 2011. The service information 

describes procedures for replacing the 

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

in the flight compartment. 

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 


pmangrum on DSK3VPTVN1PROD with PROPOSALS-1
Federal Register / Vol. 77, No. 26 / Wednesday, February 8, 2012 / Proposed Rules 6519 

the service information described 

previously. 

Costs of Compliance 

We estimate that this proposed AD 

affects 169 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 

Replacement ........................... 18 work-hours × $85 per hour = $1,530 ................................ $1,743 $3,273 $553,137 

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. 

List of Subjects in 14 CFR Part 39 

Air transportation, Aircraft, Aviation 

safety, Incorporation by reference, 

Safety.

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Notice of proposed rulemaking 

(NPRM). 

SUMMARY: We propose to adopt a new 

airworthiness directive (AD) for all BAE 

SYSTEMS (OPERATIONS) LIMITED 

Model BAe 146 and Avro 146–RJ 

airplanes. This proposed AD was 

prompted by reports of baggage bay fire 

bottles that can be misassembled such 

that two squib electrical connectors can 

be cross-connected. This proposed AD 

would require a general visual 

inspection of certain baggage bay fire 

bottles for correct connection and for 

the length of the wiring loom, modifying 

the wiring loom to certain squib 

connectors, and corrective actions if 

necessary. We are proposing this AD to 

detect and correct excessive wiring 

loom length and improper connection of 

the squib connecters, which in 

conjunction with a fire in one of the 

baggage bays, could result in the fire 

extinguishing agent being discharged 

into a wrong compartment and 

consequent damage to the airplane. 

DATES: We must receive comments on 

this proposed AD by March 26, 2012. 

ADDRESSES: You may send comments by 

any of the following methods:

Discussion 

The European Aviation Safety Agency 

(EASA), which is the Technical Agent 

for the Member States of the European 

Community, has issued EASA 

Airworthiness Directive 2011–0065, 

dated April 7, 2011 (referred to after this 

as ‘‘the MCAI’’), to correct an unsafe 

condition for the specified products. 

The MCAI states: 

The baggage bay fire bottles of certain BAe 

146 and AVRO 146–RJ aeroplanes can be 

misassembled such that two squib electrical 

connectors can be cross-connected. This has 

been caused by an error in the baggage bay 

fire bottle Component Manufacturer Manual 

(CMM) and by excessive wiring loom length. 

This condition, if not corrected and in 

conjunction with a fire in one of the baggage 

bays, could result in the fire extinguishant to 

be discharged into a wrong compartment and 

consequent potential damage to the aircraft 

* * *. 

In addition to the CMM revision, to 

address this unsafe condition, BAE Systems 

developed modifications to reroute the 

baggage bay fire bottle wiring looms and 

prevent crossed electrical connections. 

For the reasons described above, this 

[EASA] AD requires the implementation of 

modifications HCM36250A and HCM36250B 

to affected aeroplanes. 

Required actions include general 

visual inspections of certain baggage bay 

fire bottles for correct connection and 

for the length of the wiring loom, 

modifying the wiring loom to certain 

squib connectors, and corrective action 

if necessary. Corrective actions include 

reconnecting the squibs connectors and 

modifying the loom to proper length. 

You may obtain further information by 

examining the MCAI in the AD docket. 

Relevant Service Information 

BAE SYSTEMS (Operations) Limited 

has issued Modification Service Bulletin 

SB.26–077–36250A.B, Revision 4, dated 

January 7, 2011. The actions described 

in this service information are intended 

to correct the unsafe condition 

identified in the MCAI. 

FAA’s Determination and Requirements 

of This Proposed AD 

This product has been approved by 

the aviation authority of another 

country, and is approved for operation 

in the United States. Pursuant to our 

bilateral agreement with the State of 

Design Authority, we have been notified 

of the unsafe condition described in the 

MCAI and service information 

referenced above. We are proposing this 

AD 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.
