ACTION: Final rule; request for 

comments. 

SUMMARY: We are adopting a new 

airworthiness directive (AD) for the 

specified Eurocopter France 

(Eurocopter) model helicopters. This AD 

results from a mandatory continuing 

airworthiness information (MCAI) AD 

issued by the European Aviation Safety 

Agency (EASA), which is the Technical 

Agent for the Member States of the 

European Community. The MCAI AD 

was issued following the discovery of a 

potential risk of an untimely squib firing 

that would cut the hoist cable. A short 

circuit in the hoist motor brush power 

supply wiring resulting in an 

uncommanded squib firing, which cuts 

the hoist cable, constitutes an unsafe 

condition. 

DATES: This AD becomes effective on 

May 14, 2010. 

The incorporation by reference of 

Eurocopter Alert Service Bulletin No. 

25.00.85 and No. 25.00.95, both dated 

November 16, 2005, is approved by the 

Director of the Federal Register as of 

May 14, 2010. 

We must receive comments on this 

AD by June 28, 2010.

SUPPLEMENTARY INFORMATION: 

Discussion 

The EASA, which is the Technical 

Agent for the Member States of the 

European Community, has issued EASA 

AD No. 2006–0164, dated June 9, 2006, 

to correct an unsafe condition for these 

French certificated products. The MCAI 

AD states: ‘‘This AD is issued following 

the discovery of a potential risk of 

mstockstill on DSKH9S0YB1PROD with RULES

Federal Register / Vol. 75, No. 82 / Thursday, April 29, 2010 / Rules and Regulations 22509 

untimely squib firing, resulting in the 

cable being cut.’’ A short circuit in the 

hoist motor brush power supply wiring 

resulting in an uncommanded squib 

firing, which cuts the hoist cable, 

constitutes an unsafe condition. You 

may obtain further information by 

examining the MCAI AD and service 

information in the AD docket. 

Related Service Information 

Eurocopter has issued Alert Service 

Bulletin Nos. 25.00.85 and 25.00.95, 

both dated November 16, 2005. The 

actions described in the MCAI AD are 

intended to correct the same unsafe 

condition as that identified in the 

service information. 

FAA’s Evaluation and Unsafe Condition 

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, EASA, their 

Technical Agent, has notified us of the 

unsafe condition described in the MCAI 

AD. We are issuing this AD because we 

evaluated all pertinent information and 

determined the unsafe condition exists 

and is likely to exist or develop on other 

products of these same type designs. 

Differences Between This AD and the 

MCAI AD 

This AD differs from the MCAI AD in 

that it: 

• Does not include the Model BB 

helicopters but does include Model 

AS350C, D1 and AS 355 NP helicopters; 

• Does not require the actions 

specified in the Compliance section, 

paragraph 1 of the MCAI AD; 

• Does not address spares; and 

• Requires compliance before the 

next hoist operation instead of within 

30 days. 

These differences are highlighted in 

the ‘‘Differences Between This AD and 

MCAI AD’’ section of this AD. 

Costs of Compliance 

We estimate that this AD will affect 

27 helicopters of U.S. registry and that 

it will take about 2 work hours to 

modify the hoist squib wiring. The 

average labor rate is $85 per work-hour. 

Based on these figures, we estimate the 

cost to the fleet of helicopters to be 

$4,590. 

FAA’s Determination of the Effective 

Date 

An unsafe condition exists that 

requires the immediate adoption of this 

AD. The FAA has found that the risk to 

the flying public justifies waiving notice 

and comment prior to adoption of this 

rule because of the potential of the 

untimely firing of a cable cutter squib 

on Goodrich electric hoists resulting in 

the unintended cutting of a cable and 

dropping the hoist seat and occupant. 

Therefore, we determined that notice 

and opportunity for public comment 

before issuing this AD are impracticable 

and that good cause exists for making 

this amendment effective in fewer than 

30 days. 

Comments Invited 

This AD is a final rule that involves 

requirements affecting flight safety, and 

we did not precede it by notice and 

opportunity for public comment. We 

invite you to send any written relevant 

data, views, or arguments about this AD. 

Send your comments to an address 

listed under the ADDRESSES section. 

Include ‘‘Docket No. FAA–2010–0356; 

Directorate Identifier 2009–SW–72–AD’’ 

at the beginning of your comments. We 

specifically invite comments on the 

overall regulatory, economic, 

environmental, and energy aspects of 

this AD. We will consider all comments 

received by the closing date and may 

amend this 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 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 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. 

For the reasons discussed above, 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: 

2010–09–01 Eurocopter France: 

Amendment 39–16266. Docket No. 

FAA–2010–0356; Directorate Identifier 

2009–SW–72–AD. 

Effective Date 

(a) This airworthiness directive (AD) 

becomes effective on May 14, 2010. 

Other Affected ADs 

(b) None. 

Applicability 

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

B1, B2, B3, C, D and D1; and AS 355E, F, F1,

SUMMARY: This document publishes in 

the Federal Register an amendment 

adopting Airworthiness Directive (AD) 

2010–05–51, which was sent previously 

to all known U.S. owners and operators 

of ECF Model EC120B helicopters by 

individual letters. This AD requires, at 

specified intervals, inspecting the main 

rotor head rotor hub (rotor hub) for a 

crack. If you find scoring, paint flaking 

or left-over identification plate 

adhesive, the AD requires sanding the 

area until the primer coat becomes 

visible and inspecting the rotor hub for 

a crack. If you find a crack, the AD 

requires, before further flight, replacing 

the rotor hub with an airworthy rotor 

hub. This amendment is prompted by a 

mandatory continuing airworthiness 

information (MCAI) AD issued by the 

European Aviation Safety Agency 

(EASA), which is the Technical Agent 

for the Member States of the European 

Community. The MCAI AD states that 

ECF has been informed of an emergency 

landing due to excessive vibrations 

originating from the main rotor. After an 

investigation, it was determined that the 

main rotor head rotor hub (rotor hub) 

had failed in the attachment area of one 

of the three drag damper fittings. The 

actions specified by the AD are intended 

to prevent failure of a hub, excessive 

vibrations, loss of a main rotor blade, 

and subsequent loss of control of the 

helicopter. 

DATES: Effective May 14, 2010, to all 

persons except those persons to whom 

it was made immediately effective by 

Emergency AD (EAD) 2010–05–51, 

issued on February 24, 2010, which 

contained the requirements of this 

amendment. 

The incorporation by reference of 

certain publications listed in the 

regulations is approved by the Director 

of the Federal Register as of May 14, 

2010.
