**ACTION :**  Notice of proposed rulemaking (NPRM).

**SUMMARY :**  We propose to adopt a new airworthiness directive (AD) for certain Model 777–200 and –300 series airplanes. This proposed AD would require installing new operational software in the cabin management system, and loading new software into the mass memory card. This proposed AD results from an in-flight entertainment (IFE) systems review. We are proposing this AD to ensure that the flightcrew is able to turn off electricalpower to the IFE system and other nonessential electrical systems through a switch in the flight compartment in the event of smoke or flames. In the event of smoke or flames in the airplane flight deck or passenger cabin, the flightcrew’s inability to turn off electrical power to the IFE system and other non-essential electrical systems could result in the inability to control smoke or flames in the airplane flight deck or passenger cabin during a non-normal or emergency situation.

Discussion

In response to numerous reports of smoke or flames in the passenger cabin of various models of transport category airplanes, we conducted a comprehensive in-flight entertainment (IFE) systems review. Earlier investigation of the reports had revealed that the source of the smoke and flames


### 38946 Federal Register / Vol. 75, No. 129 / Wednesday, July 7, 2010 / Proposed Rules

was from cabin IFE system components, including electronic seat boxes mounted under passenger seats, IFR wirings, IFE monitors, cabin lighting, wall outlets, and other non-essential cabin electrical systems.

The systems review disclosed that in order to minimize the risk of smoke or flames in the passenger cabin, a switch is needed in the flight compartment to enable the flightcrew to turn off electrical power to the IFE system and other non-essential electrical systems. In the event of smoke or flames in the airplane flight deck or passenger cabin, the flightcrew’s inability to turn offpower to the IFE system and other nonessential electrical systems, if not corrected, could result in the inability to control smoke or flames in the airplane flight deck or passenger cabin during a non-normal or emergency situation.

Relevant Service Information

We have reviewed Boeing Service Bulletin 777–23–0175, Revision 2, dated October 12, 2006. The service bulletin describes procedures for installing new operational software in the cabin management system as follows:

• At the cabin system control panel (CSCP), remove the installed mass memory card (MMC) 285W0925–1 or 285W0925–2.

• Install the new MMC 285W0925–3.

• Install a new cabin system management unit (CSMU) software part number 2313–BCE–01T–03.

• Install a new cabin area control panel (CACP) software part number 2313–BCE–01U–02.

• Install a new zone management unit (ZMU) software part number 2374– BCE–021–02.

• Install a new overhead electronics unit (OEU) operational software (OPS) (12 port) part number 2310–BCE–01V– 02, if the airplane configuration has OEU hardware 285W0029–5 installed.

• Install a new configuration database (CDB).

• Install the new CDB to the cabin service system.

Boeing Service Bulletin 777–23–0175, Revision 2, dated October 12, 2006, specifies prior or concurrent accomplishment of Boeing Component Service Bulletin 285W0925–23–02, dated July 11, 2002, which describes procedures for loading the new cabin services system central storage device software and CSCP OPS into the MMC.
FAA’s Determination and Requirements of This Proposed AD

We are proposing this AD because we evaluated all relevant information and determined the unsafe condition described previously is likely to exist or develop in other products of these same type designs. This proposed AD would require accomplishing the actions specified in the service information described previously.
Costs of Compliance

We estimate that this proposed AD would affect 59 airplanes of U.S. registry. The following table provides the estimated costs for U.S. operators to comply with 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), and

3. 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.

You can find our regulatory evaluation and the estimated costs of compliance in the AD Docket.

**ACTION :**  Notice of proposed rulemaking (NPRM).

**SUMMARY :**  We propose to adopt a new airworthiness directive (AD) for the products listed above. This proposed AD results from mandatory continuing airworthiness information (MCAI) originated by an aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe condition as: Investigation conducted by Thales on probes revealed oil residue between the stator and the rotor parts of the AoA [angle of attack] vane position resolvers. This oil residue was due to incorrect cleaning of the machining oil during the manufacturing process of the AoA resolvers. At low temperatures, this oil residue becomes viscous (typically in cruise) causing lag of AoA vane movement. Such condition could lead to discrepant AoA measurement. If not corrected, and if two or three AoA probes were simultaneously affected and provided wrong indications of the AoA to a similar extent, it could lead to a late activation of the angle of attack protection, which in combination with light at high angle of attack would constitute an unsafe condition. The proposed AD would require actions that are intended to address the unsafe condition described in the MCAI.
