**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 ADwould require replacing the lowpressure oxygen hoses with nonconductive low-pressure oxygen hoses in the flight compartment. We are proposing this AD to prevent electricalcurrent 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:

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 tomelt 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 thelow-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


### 6519 Federal Register / Vol. 77, No. 26 / Wednesday, February 8, 2012 / Proposed Rules

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:



### E STIMATED 

### COSTS

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

**Airworthiness Directives; BAE SYSTEMS (OPERATIONS) LIMITED**  **Airplanes**

**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.

We will also post a report summarizing each substantive verbal contact we receive about this proposed AD. 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.
