AGENCY: Federal Aviation 

Administration (FAA), Department of 

Transportation (DOT). 

ACTION: Final rule. 

SUMMARY: We are adopting a new 

airworthiness directive (AD) for the 

specified Eurocopter France (ECF) 

helicopters. This AD results from a 

mandatory continuing airworthiness 

information (MCAI) AD issued by the 

aviation authority of the European 

Aviation Safety Agency (EASA), which 

is the Technical Agent for the Member 

States of the European Community. The 

superseding MCAI AD states that 

several engine flameouts have involved 

failure of the 41-tooth pinion in the 

engine accessory gearbox. Each affected 

helicopter had a starter-generator 

manufactured by one company. 

Investigation revealed the torque 

damping system of the starter-generator 

was inoperative due to incorrect 

adjustment that caused bending stresses 

on the 41-tooth pinion. Failure of the 

pinion causes the engine fuel pump to 

stop operating, resulting in an engine 

flameout. The EASA AD requires a new 

adjustment procedure to optimize the 

performance of the specified startergenerator damping assembly. This AD is 

intended to prevent failure of a pinion 

and a fuel pump, engine flameout, and 

subsequent loss of control of the 

helicopter. 

DATES: This AD becomes effective on 

June 22, 2011. 

The incorporation by reference of 

certain publications is approved by the 

Director of the Federal Register as of 

June 22, 2011.

SUPPLEMENTARY INFORMATION: 

Discussion 

We issued an NPRM to amend 14 CFR 

part 39 to include an AD that would 

apply to the specified ECF helicopters 

on December 6, 2010. That NPRM was 

published in the Federal Register on 

December 21, 2010 (75 FR 79988). That 

NPRM proposed to require within 110 

hours time-in-service or 3 months, 

whichever occurs first: 

• Modifying and marking the Aircraft 

Parts Corporation (APC) starter 

generator; and 

• Before installing an APC startergenerator with a part number (P/N) of 

150SG122Q or 200SGL130Q, complying 

with the requirements of the proposed 

AD. 

You may obtain further information 

by examining the MCAI AD and any 

related service information in the AD 

docket. 

Comments 

By publishing the NPRM, we gave the 

public an opportunity to participate in 


wwoods2 on DSK1DXX6B1PROD with RULES_PART 1
28638 Federal Register / Vol. 76, No. 96 / Wednesday, May 18, 2011 / Rules and Regulations 

developing this AD. However, we 

received no comment on the NPRM or 

on our determination of the cost to the 

public. Therefore, based on our review 

and evaluation of the available data, we 

have determined that air safety and the 

public interest require adopting the AD 

as proposed. 

Related Service Information 

ECF has issued Alert Service Bulletin 

(ASB) No. 80.00.07, Revision 1, dated 

February 6, 2009, for the Model 

AS350B, BA, BB, B1, B2, and B3 

helicopters; and ASB No. 80A003, 

Revision 1, dated February 6, 2009, for 

the Model EC130 B4 helicopters. The 

Model AS350 BB helicopter is not type 

certificated in the United States. These 

ASBs specify disassembly of the 

damping system, replacing the 

Belleville springs (cup springs) and the 

self-locking nut, and aligning the shaft 

damping system of the APC startergenerator. 

The actions described in the MCAI 

AD are intended to correct the same 

unsafe condition as that identified in 

the service information. 

Differences Between This AD and the 

MCAI AD 

The MCAI AD refers to flight hours 

instead of hours time-in-service. 

Costs of Compliance 

We estimate that this AD will affect 

about 847 helicopters. We also estimate 

that it will take about 3 work-hours per 

helicopter to modify the startergenerator. The average labor rate is $85 

per work-hour. ECF states in its ASBs 

that one nut (P/N 150SG1071, $36.12) 

and two springs (P/N 150SG1093, 

$29.14 each) are required for the P/N 

150SG122Q starter-generator and one 

nut (P/N 150SG1071, $36.12) and two 

springs (P/N 200SGL1093, $33.64 each) 

are required for the P/N 200SGL130Q 

starter-generator. Based on these figures, 

we estimate the cost of this AD on U.S. 

operators to be $299,749 ($215,985 for 

labor and $83,764 for parts), assuming 

that both starter-generators are evenly 

distributed in the fleet and that the 

entire fleet is modified. 

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 AD will not 

have federalism implications under 

Executive Order 13132. This AD will 

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. 

Therefore, I certify this AD: 

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. 

We prepared an economic evaluation 

of the estimated costs to comply with 

this AD and placed it in the AD docket.

Adoption of the Amendment 

Accordingly, under the authority 

delegated to me by the Administrator, 

the FAA amends 14 CFR part 39 as 

follows: 

PART 39—AIRWORTHINESS 

DIRECTIVES 

■ 1. The authority citation for part 39 

continues to read as follows: 

Authority: 49 U.S.C. 106(g), 40113, 44701. 

§ 39.13 [Amended] 

■ 2. The FAA amends § 39.13 by adding 

the following new AD: 

2011–10–12 Eurocopter France: 

Amendment 39–16693; Docket No. 

FAA–2010–1228; Directorate Identifier 

2009–SW–12–AD. 

Effective Date 

(a) This airworthiness directive (AD) 

becomes effective on June 22, 2011. 

Other Affected ADs 

(b) None. 

Applicability 

(c) This AD applies to Model AS350B, B1, 

B2, B3, BA, and EC130 B4 helicopters with 

ARRIEL engines with Aircraft Parts 

Corporation (APC) starter-generators, part 

number (P/N) 150SG122Q or P/N 

200SGL130Q, without ‘‘004’’ marked on the 

identification plate, installed, certificated in 

any category. 

Reason 

(d) The mandatory continuing 

airworthiness information (MCAI) AD states 

that several engine flameouts involved failure 

of the 41-tooth pinion in the engine accessory 

gearbox that caused the engine fuel pump to 

fail. Each affected helicopter had an APC 

(currently UNISON) starter-generator 

installed. Investigation revealed the torque 

damping system of the starter-generator was 

inoperative. The EASA AD requires a new 

adjustment procedure to optimize the 

performance of the specified starter-generator 

damping assembly. The required actions are 

intended to prevent failure of a pinion and 

a fuel pump, engine flameout, and 

subsequent loss of control of the helicopter. 

Actions and Compliance 

(e) Within 110 hours time-in-service (TIS) 

or 3 months, whichever occurs first, unless 

already accomplished, do the following: 

(1) Replace the cup springs and fan nut, 

functionally test the damping system, and 

after this modification, mark ‘‘004’’ on the 

identification plate of the APC starter 

generator, as depicted in Figures 1 and 2, and 

by following the Accomplishment 

Instructions, paragraph 2.B.2., of Eurocopter 

Alert Service Bulletin (ASB) No. 80.00.07, 

Revision 1, dated February 6, 2009, for the 

Model AS350B, BA, B1, B2, and B3 

helicopters; or ASB No. 80A003, Revision 1, 

dated February 6, 2009, for the Model EC130 

B4 helicopter. 

(2) Before installing an APC startergenerator with P/N 150SG122Q or P/N 

200SGL130Q, comply with the requirements 

of this AD. 

Differences Between This AD and the MCAI 

AD 

(f) The MCAI AD refers to flight hours 

instead of hours time-in-service.

ACTION: Final rule. 

SUMMARY: We are adopting a new 

airworthiness directive (AD) for the 

products listed above. This AD results 

from mandatory continuing 

airworthiness information (MCAI) 

issued by an airworthiness authority of 

another country to identify and correct 

an unsafe condition on an aviation 

product. The MCAI describes the unsafe 

condition as: 

During production quality inspections of 

the aeroplane fuel motive flow system, it was 

discovered that some motive flow check 

valves (MFCV) were manufactured with an 

outlet fitting containing red anodized 

threads. These MFCV do not provide 

adequate electrical bonding between the 

valve and the adjacent fitting. 

In the absence of proper electrical bonding 

within the motive flow system, the aeroplane 

fuel tank could be exposed to ignition 

sources in the case of a lightning strike. 

* * * * * 

The unsafe condition is the potential for 

ignition sources inside the fuel tanks, 

which, in combination with flammable 

fuel vapors, could result in a fuel tank 

explosion and consequent loss of the 

airplane. We are issuing this AD to 

require actions to correct the unsafe 

condition on these products. 

DATES: This AD becomes effective June 

22, 2011. 

The Director of the Federal Register 

approved the incorporation by reference 

of a certain publication listed in this AD

SUPPLEMENTARY INFORMATION: 

Discussion 

We issued a notice of proposed 

rulemaking (NPRM) to amend 14 CFR 

part 39 to include an AD that would 

apply to the specified products. That 

NPRM was published in the Federal 

Register on February 23, 2011 (76 FR 

9982). The MCAI states: 

During production quality inspections of 

the aeroplane fuel motive flow system, it was 

discovered that some motive flow check 

valves (MFCV) were manufactured with an 

outlet fitting containing red anodized 

threads. These MFCV do not provide 

adequate electrical bonding between the 

valve and the adjacent fitting. 

In the absence of proper electrical bonding 

within the motive flow system, the aeroplane 

fuel tank could be exposed to ignition 

sources in the case of a lightning strike. 

This [TCCA] directive is issued to [do a 

general visual inspection to] verify the proper 

configuration of the MFCV and if required, 

replace the affected MFCV with a MFCV that 

has a chemically filmed (gold color) outlet 

valve fitting, which provides adequate 

electrical bonding. 

The unsafe condition is the potential for 

ignition sources inside the fuel tanks, 

which, in combination with flammable 

fuel vapors, could result in a fuel tank 

explosion and consequent loss of the 

airplane. You may obtain further 

information by examining the MCAI in 

the AD docket. 

Comments 

We gave the public the opportunity to 

participate in developing this AD. We 

received no comments on the NPRM or 

on the determination of the cost to the 

public. 

Conclusion 

We reviewed the available data and 

determined that air safety and the 

public interest require adopting the AD 

as proposed. 

Costs of Compliance 

Based on the service information, we 

estimate that this AD affects about 67 

products of U.S. registry. We also 

estimate that it takes about 33 workhours per product to comply with the 

basic requirements of this AD. The 

average labor rate is $85 per work-hour. 

Required parts will cost about $130 per 

product. Based on these figures, we 

estimate the cost of the AD on U.S. 

operators to be $196,645, or $2,935 per 

product.
