interphone controller, speaker drive module, overhead electronics units, and seat electronics unit. The NPRM resulted from an IFE systems review. The proposed actions were intended to ensure that the flightcrew is able to turn off electrical power to the IFE system and other non-essential electrical systems through a switch in the flight compartment in the event of smoke or flames. The flightcrew’s inability to turn off electrical power to the IFE system and other non-essential electrical systems in the event of smoke or flames could result in the inability to control smoke or flames in the airplane flightdeck or passenger cabin during a nonnormal or emergency situation.
Actions Since NPRM (76 FR 5505, February 1, 2011) Was Issued

Since we issued the NPRM (76 FR 5505, February 1, 2011), we have received new data that indicates the unsafe condition would not be adequately addressed by the proposed action. Subsequently, we are considering issuing new rulemaking that positively addresses the unsafe condition identified in the NPRM and eliminates the need for the actions proposed in the NPRM.

FAA’s Conclusions

Upon further consideration, we have determined that the unsafe condition still exists, however, we intend to address it with new AD rulemaking. Accordingly, the NPRM (76 FR 5505, February 1, 2011) is withdrawn.

Withdrawal of the NPRM (76 FR 5505, February 1, 2011) does not preclude the FAA from issuing another related action or commit the FAA to any course of action in the future. Regulatory Impact

Since this action only withdraws an NPRM (76 FR 5505, February 1, 2011), it is neither a proposed nor a final rule and therefore is not covered under Executive Order 12866, the Regulatory Flexibility Act, or DOT Regulatory Policies and Procedures (44 FR 11034, February 26, 1979).

The Withdrawal

Accordingly, we withdraw the NPRM, Docket No. FAA–2011–0034, Directorate Identifier 2010–NM–021–AD, which published in the Federal Register on February 1, 2011 (76 FR 5505).

**ACTION :**  Proposed rule; withdrawal.

**SUMMARY :**  The FAA withdraws a notice of proposed rulemaking (NPRM) that proposed a new airworthiness directive (AD) for certain The Boeing Company Model 777–200 series airplanes. The proposed AD would have required installing a new circuit breaker, relays, and wiring to allow the flightcrew to turn off electrical power to the in-flight entertainment (IFE) systems and other non-essential electrical systems through a switch in the flight compartment, and doing other specified actions. That NPRM would also have required changing the wiring at the cabin management system in the purser station. Since the proposed AD was issued, we have received new data that indicates the unsafe condition would not be adequately addressed by the proposed action. Subsequently, we are considering issuing new rulemaking that positively addresses the unsafe condition identified in the NPRM and eliminates the need for the actions proposed in the NPRM. Accordingly, the proposed AD is withdrawn.

Discussion

We proposed to amend part 39 of the Federal Aviation Regulations (14 CFR part 39) with a notice of proposed rulemaking (NPRM) for a new AD for certain Model 777–200 series airplanes. That NPRM published in the Federal Register on February 1, 2011 (76 FR 5503). The NPRM would have required installing a new circuit breaker, relays, and wiring to allow the flightcrew to turn off electrical power to the IFE systems and other non-essential electrical systems through a switch in the flight compartment, and doing other specified actions. The actions included replacing the cabin area control panels; changing the wiring; modifying the purser station or the A–4 galley, as applicable; installing new cabin system management unit, cabin area control panel, overhead electronics unit, and zone management units operational software, as applicable; and making a change to the cabin services system (CSS) configuration database and installing the new database in the CSS components. That NPRM would also have required changing the wiring at the cabin management system in the purser station. The NPRM resulted from an IFE systems review. The proposed actions were intended 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. The flightcrew’s inability to turn off electrical power to the IFE system and other non-essential electrical systems in the event of smoke or flames 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.

**Airworthiness Directives; Eurocopter France Helicopters** 

**AGENCY :**  Federal Aviation Administration (FAA), DOT.

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

**SUMMARY :**  We propose to adopt a new airworthiness directive (AD) for Eurocopter France (Eurocopter) Model AS350B, BA, B1, B2, B3, and D, and Model AS355E, F, F1, F2, and N helicopters with certain tail rotor (T/R) blades. This proposed AD would require installing additional rivets to secure each T/R blade trailing edge tab (tab), and inspecting for evidence of debonding of the tab after the rivets are installed. This proposed AD is prompted by reports of T/R blade tab debonding. The actions specified by this proposed AD are intended to prevent loss of a T/R blade tab, which could result in excessive vibration and loss of control of the helicopter.

**DATES :**  We must receive comments on this proposed AD by June 21, 2013.

**ADDRESSES :**  You may send comments by any of the following methods:

• Federal eRulemaking Docket: Go to http://www.regulations.gov. Follow the online instructions for sending your comments electronically.

• Fax: 202–493–2251.

Discussion

The Direction Generale de l’Aviation Civile (DGAC), which is the aviation authority for France, has issued DGAC AD No. F–2004–178, dated November 10, 2004, for the Eurocopter AS 350B, BA, BB, B1, B2, B3, and D helicopters, fitted with certain T/R blades. DGAC has also issued AD No. F–2004–176, dated November 10, 2004, for the Eurocopter Model AS 355E, F, F1, F2, and N helicopters with certain T/R blades. DGAC advises of reports of T/R blade tab debonding, and that the loss of the tab leads to a significant increase in the aircraft’s vibration level. As a result, the ADs mandate compliance with the manufacturer’s service information to install additional rivets on the tabs.

FAA’s Determination

These helicopters have been approved by the aviation authority of France and are approved for operation in the United States. Pursuant to our bilateral agreement with France, the European Aviation Safety Agency, which is the Technical Agent for the Member States of the European Union, has notified us of the unsafe condition described in the DGAC AD. We are proposing this AD because we evaluated all known relevant information and determined that an unsafe condition is likely to
