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 PO 00000 Frm 00006 Fmt 4700 Sfmt 4700 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.

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 E:\FR\FM\29APR1.SGM 29APR1 Federal Register / Vol. 75, No. 82 / Thursday, April 29, 2010 / Rules and Regulations 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. 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 https:// 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. FAA’s Determination of the Effective Date 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. 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 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 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. mstockstill on DSKH9S0YB1PROD with RULES 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.

ACTION: Final rule; request for comments. 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, PO 00000 Frm 00008 Fmt 4700 Sfmt 4700 and subsequent loss of control of the helicopter.

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.

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

[[Page 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

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

0
Accordingly, under the authority delegated to me by the Administrator, 
the FAA amends 14 CFR part 39 as follows:

PART 39--AIRWORTHINESS DIRECTIVES

0
1. The authority citation for part 39 continues to read as follows:

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


Sec.  39.13  [Amended]

0
2. The FAA amends Sec.  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, F2, N, and NP helicopters with a Goodrich 
Electric hoist, part number (P/N) 76370-XXX, which has not been 
modified per Modification (MOD) 073318 and with a hoist motor other 
than an AUXILEC, installed, certificated in any category.

Reason

    (d) The mandatory continued airworthiness (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.

[[Page 22510]]

Actions and Compliance

    (e) Before the next hoist operation, unless already 
accomplished, disconnect the ground wire for the hoist squib wiring 
and test the hoist system to assure that the squib can be 
electrically fired (MOD 073318) by following the Accomplishment 
Instructions, Paragraph 2.B.1. through 2.B.4., of Eurocopter Alert 
Service Bulletin (ASB) No. 25.00.95, for the AS350 model helicopters 
or ASB No. 25.00.85, for the AS355 model helicopters, both dated 
November 16, 2005, as appropriate for your model helicopter.

Differences Between This AD and the MCAI AD

    (f) This AD differs from the MCAI AD in that it:
    (1) Does not include the Model BB helicopters but does include 
the Model AS350C and D1 and Model AS355NP helicopters;
    (2) Does not require the actions specified in the Compliance 
section, paragraph 1 of the MCAI AD;
    (3) Does not address spares; and
    (4) Requires compliance before the next hoist operation instead 
of within 30 days.

Other Information

    (g) Alternative Methods of Compliance (AMOCs): The Manager, 
Safety Management Group, FAA, ATTN: George Schwab, Aerospace 
Engineer, Rotorcraft Directorate, Fort Worth, Texas 76193-0112,

approve AMOCs for this AD, if requested, using the procedures found 
in 14 CFR 39.19.
    (h) Special Flight Permits: Special flight permits may be issued 
under 14 CFR 21.197 and 21.199 to operate the helicopter to a 
location where the requirements of this AD can be done provided that 
the hoist is not used.
