**[Docket No. FAA–2012–0222; Directorate Identifier 2011–SW–007–AD]** 

**RIN 2120–AA64**

**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 certain Eurocopter France Model AS350 helicopters. This proposed AD is prompted by an in-flight fire caused by ignition of hydraulic fluid leaking from a damaged forward (pitch) servo-control hydraulic hose. The proposed actions are intended to prevent the forward servo-control hydraulic hoses from becoming damaged and leaking hydraulic fluid that could ignite in flight, which can result in loss of main rotor control, power loss, structural damage, propagation of fire, and subsequent loss of control of the helicopter.

Discussion

The European Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European Union, has issued AD No. 2011–0033, dated March 1, 2011 (AD 2011–0033) to correct an unsafe condition for the Eurocopter AS350 B, BA, BB, D, B1, B2, and B3 helicopters with a single hydraulic power system and forward (pitch) servo-control hydraulic hoses part number (P/N) 704A34–412–033 (other reference manufacturer’s part number (MP/N) 675–102–05–01) and P/N 704A34–412–035 (other reference MP/N 675–102–06–01) installed. EASA


### 14311 Federal Register / Vol. 77, No. 47 / Friday, March 9, 2012 / Proposed Rules

advises that an in-flight fire in the main gearbox compartment occurred on an AS350B2 helicopter, ‘‘caused by ignition of hydraulic fluid leaking from a hydraulic hose that had been damaged following an electrical fault in a circuit located in the compartment, which is not fire protected. An in-flight fire in the main gearbox compartment during a continued flight, when undetected or where a landing could not be performed immediately, could result in loss of hydraulics, shutdown of the engine because of fire effects, and damage to the Main Rotor (M/R) control system.’’ This condition, if not prevented, could lead to loss of M/R control, power loss, structural damage, propagation of fire into the cabin or other compartments, and subsequent loss of control of the helicopter. For these reasons, AD 2011– 0033 requires installation of protection sleeves on the affected hydraulic hoses.

FAA’s Determination

These products 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, EASA, their technical representative, has notified us of the unsafe condition described in their AD. We are proposing this AD because we evaluated all known relevant information and determined that an unsafe condition is likely to exist or develop on other helicopters of the same type design.

Related Service Information

Eurocopter has issued Alert Service Bulletin No. 29.00.13, dated July 26, 2010 (ASB 29.00.13), which specifies installing two siliconed glass wool sleeves over both forward main rotor servo-control hydraulic hoses. EASA classified this ASB as mandatory and issued AD 2011–0033 to ensure the continued airworthiness of these helicopters. Proposed AD Requirements

This proposed AD would require, within 30 days, installing protectionsleeves over the forward (pitch) servocontrol hydraulic hoses in accordance with paragraph 2.B.2 of ASB 29.00.13. Differences Between This Proposed AD and the EASA AD

The EASA AD applies to the Eurocopter Model AS350 BB. The proposed AD does not, as this model is not type certificated in the U.S. Costs of Compliance

We estimate that this proposed AD would affect 695 helicopters of U.S. Registry. We estimate that operators may incur the following costs in order to comply with this AD. Disconnecting the servo control hoses, installing the protective sleeves, reconnecting the hoses, and testing for interference requires one work hour at an average labor rate of $85 per hour. Required parts cost $212, for a total cost of $297 for each helicopter. Based upon these costs, we estimate a total cost to the U.S. operator fleet of $206,415. 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 helicopters 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, 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 to the extent that it justifies making a regulatory distinction; 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.

We prepared an economic evaluation of the estimated costs to comply with this proposed AD and placed it in the AD docket. List of Subjects in 14 CFR Part 39 Air transportation, Aircraft, Aviation safety, Incorporation by Reference, Safety. The Proposed Amendment

Accordingly, under the authority delegated to me by the Administrator, the FAA proposes to amend 14 CFR part 39 as follows:

**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– 2012–0195; Directorate Identifier 2012– NE–08–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 two reports of engines experiencing uncontained release of LP turbine blades. Investigation revealed that the overspeed trip system on both of these engines had a preexisting (latent) failure when the fan decoupled from the LP turbine, due to a certain part failing in the reduction gearbox. This condition, if not corrected, could result in LP turbine overspeed leading to uncontained release of the LP turbine blades and damage to the airplane.

Relevant Service Information

We reviewed Honeywell International, Inc. ALF502L Engine Maintenance Manual Section 72–00–00, Inspection/Check-10, dated October 31, 2000; ALF502R Engine Manual Section 72–00–00, Inspection/Check-09, dated July 31, 2000; LF507–1F Engine Manual Section 72–00–00, Inspection/Check-08, Temporary Revision 72–146, dated November 3, 2006; and LF507–1H Engine Manual Section 72–00–00, Inspection/Check-08, dated September 30, 1999. The service information describes procedures for operational checks of the overspeed trip system.

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 initial and repetitive operational checks of the overspeed trip system.
Costs of Compliance

We estimate that this proposed AD would affect 188 Honeywell International, Inc. ALF502L–2C; ALF502R–3; ALF502R–3A; ALF502R–5; LF507–1F; and LF507–1H turbofan engines, installed on airplanes of U.S. registry. We also estimate that it would take about one work-hour to perform an operational check of the overspeed trip system on each engine. The average labor rate is $85 per work-hour. Based on these figures, we estimate the total cost of this proposed AD for one operational check of the overspeed trip system to U.S. operators, to be $15,980.
