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. 

DATES: We must receive comments on 

this proposed AD by May 8, 2012.

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 


sroberts on DSK5SPTVN1PROD with PROPOSALS
Federal Register / Vol. 77, No. 47 / Friday, March 9, 2012 / Proposed Rules 14311 

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 protection 

sleeves 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.

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.
