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.

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
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.

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.

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.

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

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
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.
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 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.

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
