DEPARTMENT OF TRANSPORTATION Federal Aviation Administration 14 CFR Part 39 Federal Aviation Administration (FAA), Department of Transportation (DOT). ACTION: Final rule; request for comments. AGENCY: SUMMARY: We are adopting a new airworthiness directive (AD) for Eurocopter France Model AS 355 F2 and AS 355 N helicopters. This AD results from mandatory continuing airworthiness information (MCAI) originated by an aviation authority to identify and correct an unsafe condition on an aviation product. The European Aviation Safety Agency, the Technical Agent for France, with which we have a bilateral agreement, states in the MCAI: This emergency Airworthiness Directive (AD) is issued following a report of yaw control restricted travel in operation following the replacement of the load compensator. If not corrected, this condition could lead to the loss of control of the helicopter. This AD requires actions that are intended to address this unsafe condition. This AD becomes effective February 12, 2008. The Director of the Federal Register approved the incorporation by reference of Eurocopter Emergency Alert Service Bulletin No. 67.00.29, Revision 1, dated April 27, 2007, as of February 12, 2008. sroberts on PROD1PC70 with RULES DATES: VerDate Aug<31>2005 19:34 Jan 25, 2008 Jkt 214001 Streamlined Issuance of AD The FAA is implementing a new process for streamlining the issuance of ADs related to MCAI. This streamlined process will allow us to adopt MCAI safety requirements in a more efficient manner and will reduce safety risks to the public. This process continues to follow all FAA AD issuance processes to meet legal, economic, Administrative Procedure Act, and Federal Register requirements. We also continue to meet our technical decision-making responsibilities to identify and correct unsafe conditions on U.S.-certificated products. This AD references the MCAI and related service information that we considered in forming the engineering PO 00000 Frm 00001 Fmt 4700 Sfmt 4700 basis to correct the unsafe condition. The AD contains text copied from the MCAI and for this reason might not follow our plain language principles. Discussion The European Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European Community, has issued EASA Airworthiness Directive 2007–0131–E, dated May 11, 2007 (referred to after this as ‘‘the MCAI’’), to correct an unsafe condition for these French-certificated helicopters. The MCAI states: This emergency Airworthiness Directive (AD) is issued following a report of yaw control restricted travel in operation following the replacement of the load compensator. If not corrected, this condition could lead to the loss of control of the helicopter. Investigation revealed that the load compensator lever was incorrectly referenced in the Illustrated Parts Catalog (IPC). Levers on helicopters Post-MOD 072065 (replacement of the load compensator hydraulic actuator) should be Part Number (P/N) 355A27–0082–00 and levers on helicopters Pre-MOD 072065 should be P/N 355A27–0072–00. This AD mandates inspection to identify the load compensator lever and the hydraulic actuator assembly installed on helicopters, to verify their compatibility and replacement of improper P/Ns when an incompatibility is found. The installation of an incompatible load compensator lever in a Pre-Mod 072065 helicopter may cause control travel restrictions while the installation of an incompatible load compensator lever in a Post-Mod 072065 helicopter may cause increased control loads in the yaw control pedals. You may obtain further information by examining the MCAI and service information in the AD docket. Relevant Service Information Eurocopter has issued Emergency Alert Service Bulletin (ASB) No. 67.00.29, Revision 1, dated April 27, 2007. The actions described in the MCAI are intended to correct the same unsafe condition as that identified in the service information. FAA’s Determination and Requirements of This AD This product has been approved by the aviation authority of France, and is approved for operation in the United States. Pursuant to our bilateral agreement with this State of Design Authority, we have been notified of the unsafe condition described in the MCAI E:\FR\FM\28JAR1.SGM 28JAR1 4684 Federal Register / Vol. 73, No. 18 / Monday, January 28, 2008 / Rules and Regulations and service information. 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 the same type design. Differences Between the AD and the MCAI or Service Information 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. Costs of Compliance We have reviewed the MCAI and related service information and, in general, agree with their substance. However, the requirements of this AD must be accomplished within 10 hours TIS after the effective date of this AD. The MCAI requires accomplishment before next flight. Additionally, this AD requires that components with bore diameters outside the tolerances specified in the ASB be replaced with airworthy components with bore diameters within the specified tolerances instead of contacting the manufacturer for a ‘‘suitable repair solution.’’ These differences are highlighted in the ‘‘Differences Between the FAA AD and the MCAI’’ section in the AD. 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 installation of an incompatible load compensator lever may result in restricted yaw control travel or increased control loads in the yaw control pedals and the incompatibility must be corrected within 10 hours TIS. 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. sroberts on PROD1PC70 with RULES 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–2008–0043; Directorate Identifier 2007–SW–31–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. VerDate Aug<31>2005 19:34 Jan 25, 2008 Jkt 214001 We estimate that this AD will affect about 36 products of U.S. registry. We also estimate that it will take about .25 work-hour to inspect the helicopter and 10 work-hours to replace a load compensator lever, if needed. The average labor rate is $80 per work-hour. Required parts will cost about $1,161 for a load compensator lever, P/N 355A27– 0072–00, or $862 for a load compensator lever, P/N 355A27–0082–00. Based on these figures, we estimate the cost of this AD on U.S. operators to be $720 to inspect, or $20 per product, assuming no load compensation levers are replaced. 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 PO 00000 Frm 00002 Fmt 4700 Sfmt 4700 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. List of Subjects in 14 CFR Part 39 Air transportation, Aircraft, Aviation safety, Incorporation by reference, Safety. Adoption of the Amendment Accordingly, under the authority delegated to me by the Administrator, the FAA amends 14 CFR part 39 as follows: I PART 39—AIRWORTHINESS DIRECTIVES 1. The authority citation for part 39 continues to read as follows: I Authority: 49 U.S.C. 106(g), 40113, 44701. § 39.13 [Amended] 2. The FAA amends § 39.13 by adding the following new AD: I 2008–02–10 Eurocopter France: Amendment 39–15340. Docket No. FAA–2008–0043; Directorate Identifier 2007–SW–31–AD.

Airworthiness Directives; Eurocopter France Model AS 355 F2 and 
AS 355 N Helicopters

AGENCY: Federal Aviation Administration (FAA), Department of 
Transportation (DOT).

ACTION: Final rule; request for comments.

-----------------------------------------------------------------------

SUMMARY: We are adopting a new airworthiness directive (AD) for 
Eurocopter France Model AS 355 F2 and AS 355 N helicopters. This AD 
results from mandatory continuing airworthiness information (MCAI) 
originated by an aviation authority to identify and correct an unsafe 
condition on an aviation product. The European Aviation Safety Agency, 
the Technical Agent for France, with which we have a bilateral 
agreement, states in the MCAI:

    This emergency Airworthiness Directive (AD) is issued following 
a report of yaw control restricted travel in operation following the 
replacement of the load compensator. If not corrected, this 
condition could lead to the loss of control of the helicopter.

    This AD requires actions that are intended to address this unsafe 
condition.

DATES: This AD becomes effective February 12, 2008.
    The Director of the Federal Register approved the incorporation by 
reference of Eurocopter Emergency Alert Service Bulletin No. 67.00.29,

SUPPLEMENTARY INFORMATION: 

Streamlined Issuance of AD

    The FAA is implementing a new process for streamlining the issuance 
of ADs related to MCAI. This streamlined process will allow us to adopt 
MCAI safety requirements in a more efficient manner and will reduce 
safety risks to the public. This process continues to follow all FAA AD 
issuance processes to meet legal, economic, Administrative Procedure 
Act, and Federal Register requirements. We also continue to meet our 
technical decision-making responsibilities to identify and correct 
unsafe conditions on U.S.-certificated products.
    This AD references the MCAI and related service information that we 
considered in forming the engineering basis to correct the unsafe 
condition. The AD contains text copied from the MCAI and for this 
reason might not follow our plain language principles.

Discussion

    The European Aviation Safety Agency (EASA), which is the Technical 
Agent for the Member States of the European Community, has issued EASA 
Airworthiness Directive 2007-0131-E, dated May 11, 2007 (referred to 
after this as ``the MCAI''), to correct an unsafe condition for these 
French-certificated helicopters. The MCAI states:

    This emergency Airworthiness Directive (AD) is issued following 
a report of yaw control restricted travel in operation following the 
replacement of the load compensator. If not corrected, this 
condition could lead to the loss of control of the helicopter. 
Investigation revealed that the load compensator lever was 
incorrectly referenced in the Illustrated Parts Catalog (IPC). 
Levers on helicopters Post-MOD 072065 (replacement of the load 
compensator hydraulic actuator) should be Part Number (P/N) 355A27-
0082-00 and levers on helicopters Pre-MOD 072065 should be P/N 
355A27-0072-00. This AD mandates inspection to identify the load 
compensator lever and the hydraulic actuator assembly installed on 
helicopters, to verify their compatibility and replacement of 
improper P/Ns when an incompatibility is found.

The installation of an incompatible load compensator lever in a Pre-Mod 
072065 helicopter may cause control travel restrictions while the 
installation of an incompatible load compensator lever in a Post-Mod 
072065 helicopter may cause increased control loads in the yaw control 
pedals. You may obtain further information by examining the MCAI and 
service information in the AD docket.

Relevant Service Information

    Eurocopter has issued Emergency Alert Service Bulletin (ASB) No. 
67.00.29, Revision 1, dated April 27, 2007. The actions described in 
the MCAI are intended to correct the same unsafe condition as that 
identified in the service information.

FAA's Determination and Requirements of This AD

    This product has been approved by the aviation authority of France, 
and is approved for operation in the United States. Pursuant to our 
bilateral agreement with this State of Design Authority, we have been 
notified of the unsafe condition described in the MCAI

[[Page 4684]]

and service information. 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 the same type 
design.

Differences Between the AD and the MCAI or Service Information

    We have reviewed the MCAI and related service information and, in 
general, agree with their substance. However, the requirements of this 
AD must be accomplished within 10 hours TIS after the effective date of 
this AD. The MCAI requires accomplishment before next flight. 
Additionally, this AD requires that components with bore diameters 
outside the tolerances specified in the ASB be replaced with airworthy 
components with bore diameters within the specified tolerances instead 
of contacting the manufacturer for a ``suitable repair solution.''
    These differences are highlighted in the ``Differences Between the 
FAA AD and the MCAI'' section in the AD.

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 
installation of an incompatible load compensator lever may result in 
restricted yaw control travel or increased control loads in the yaw 
control pedals and the incompatibility must be corrected within 10 
hours TIS. 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

Costs of Compliance

    We estimate that this AD will affect about 36 products of U.S. 
registry. We also estimate that it will take about .25 work-hour to 
inspect the helicopter and 10 work-hours to replace a load compensator 
lever, if needed. The average labor rate is $80 per work-hour. Required 
parts will cost about $1,161 for a load compensator lever, P/N 355A27-
0072-00, or $862 for a load compensator lever, P/N 355A27-0082-00. 
Based on these figures, we estimate the cost of this AD on U.S. 
operators to be $720 to inspect, or $20 per product, assuming no load 
compensation levers are replaced.

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:

2008-02-10 Eurocopter France: Amendment 39-15340. Docket No. FAA-
2008-0043; Directorate Identifier 2007-SW-31-AD.

Effective Date

    (a) This airworthiness directive (AD) becomes effective February 
12, 2008.

Other Affected ADs

    (b) None.

Applicability

    (c) This AD applies to Eurocopter Model AS 355 F2 and AS 355 N 
helicopters, all serial numbers, certificated in any category.

Reason

    (d) The mandatory continued airworthiness information (MCAI) 
states:
    This emergency Airworthiness Directive (AD) is issued following 
a report of yaw control restricted travel in operation following the 
replacement of the load compensator. If not corrected, this 
condition could lead to the loss of control of the helicopter.
    Investigation revealed that the load compensator lever was 
incorrectly referenced in the Illustrated Parts Catalog (IPC). 
Levers on helicopters Post-MOD 072065 (replacement of the load 
compensator hydraulic actuator) should be Part Number (P/N) 355A27-
0082-00 and levers on helicopters Pre-MOD 072065 should be P/N 
355A27-0072-00. This AD mandates inspection to identify the load 
compensator lever and the hydraulic actuator assembly installed on 
helicopters, to verify their compatibility and replacement of 
improper P/Ns when an incompatibility is found.

Actions and Compliance

    (e) Unless already done, do the following:

[[Page 4685]]

    (1) Within the next 10 hours time-in-service (TIS), determine 
the part number (P/N) and the compatibility of the load compensator 
lever (compensator level) and the hydraulic actuator assembly 
(hydraulic actuator) in accordance with the Accomplishment 
Instructions, paragraphs 2.B.1. through 2.B.2.c. of Eurocopter AS 
355 Emergency Alert Service Bulletin No. 67.00.29, Revision 1, April 
27, 2007 (ASB).

    Note: Instead of inspecting the rotorcraft, a review of the 
helicopter maintenance records along with any other applicable data 
(rotorcraft logbook, components list, etc.) is acceptable if each P/
N can be positively determined from that review.

    (2) For helicopters, Pre-Mod 072065, with an incompatible 
hydraulic actuator, P/N 355A75-1370-01 or P/N 355A75-1370-03, and 
compensator lever, P/N 355A27-0082-00:
    (i) If the helicopter has NOT been operated with compensator 
lever, P/N 355A27-0082-00, installed, replace the compensator lever 
before further flight with an airworthy compensator lever, P/N 
355A27-0072-00.
    (ii) If the helicopter has been operated with compensator lever, 
P/N 355A27-0082-00, installed, within the next 10 hours time-in-
service (TIS):
    (A) Remove the load compensator assembly and the compensator 
lever, measure the diameters of the bores, inspect the swivel 
bearings, replace the specified hydraulic actuator components and 
the incompatible compensator lever and install the load compensator 
assembly in accordance with the applicable steps in the 
Accomplishment Instructions, paragraph 2.B.3.b. of the ASB.
    (B) If the diameter of a bore is greater than the tolerances 
specified in the applicable steps in the Accomplishment 
Instructions, paragraph 2.B.3.b., of the ASB, replace each part that 
contains an out-of-tolerance bore diameter with an airworthy part 
that contains a bore diameter that is within the specified 
tolerances.
    (3) For helicopters, Post-MOD 072065, with an incompatible 
hydraulic actuator, P/N 355A75-1370-02 or P/N 355A75-1370-04, and 
compensator lever, P/N 355A27-0072-00:
    (i) If the helicopter has NOT been operated with compensator 
lever, P/N 355A27-0072-00, installed, replace the compensator lever 
before further flight with an airworthy compensator lever, P/N 
355A27-0082-00.
    (ii) If the helicopter has been operated with compensator lever, 
P/N 355A27-0072-00, installed, within the next 10 hours TIS, replace 
the compensator lever with an airworthy compensator lever, P/N 
355A27-0082-00, and inspect the bolts in accordance with the 
applicable steps in the Accomplishment Instructions, paragraph 
2.B.3.b.of the ASB.
    (f) No person shall install a:
    (1) Load compensator lever, P/N 355A27-0082-00, on any Model AS 
355 N or AS 355 F2 helicopter Pre-MOD 072065, with hydraulic 
actuator assembly, P/N 355A75-1370-01 or P/N 355A75-1370-03; or a
    (2) Load compensator lever, P/N 355A27-0072-00, on any Model AS 
355 N or AS 355 F2 helicopter Post-MOD 072065, with hydraulic 
actuator assembly, P/N 355A75-1370-02 or P/N 355A75-1370-04.

Differences Between the FAA AD and the MCAI

    (g) The requirements of this AD must be accomplished within 10 
hours TIS after the effective date of this AD. The MCAI requires 
accomplishment before next flight. Additionally, this AD requires 
that components with bore diameters outside the tolerances specified 
in the ASB be replaced with airworthy components with bore diameters 
within the specified tolerances instead of contacting the 
manufacturer for a ``suitable repair solution.''
