AGENCY: Federal Aviation
Administration (FAA), Department of
Transportation (DOT).
ACTION: Final rule.
SUMMARY: We are adopting a new
airworthiness directive (AD) for the
specified 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
states that the AD is issued following a
manufacturing nonconformity found on
one batch of the servo-control caps.
With a defective servo-control, rotation
of the distributor might not be stopped
mechanically since only friction of
inner seals holds the distributor sleeve
in its position. The AD actions are
intended to address the unsafe
condition created by a manufacturing
nonconformity found on one batch of
servo-control caps. If not corrected this
condition could cause untimely
movements of servo-controls, which are
used on main and anti-torque rotors,
and lead to the loss of control of the
helicopter.
DATES: This AD becomes effective on
April 21, 2010.
The incorporation by reference of
certain publications is approved by the
Director of the Federal Register as of
April 21, 2010.

SUPPLEMENTARY INFORMATION:
Discussion
We issued an NPRM to amend 14 CFR
part 39 to include an AD that would
apply to the Eurocopter France Model
AS 332 C, L, L1, and L2; AS 350 B3;
AS355 F, F1, F2, and N; SA 365N and
N1; AS 365 N2 and N3; SA 366G1; EC
130 B4; and EC 155B and B1 helicopters
on July 14, 2009. That NPRM was
published in the Federal Register on
August 3, 2009 (74 FR 38381). That
NPRM proposed to address the unsafe
condition created by a manufacturing
nonconformity found on one batch of
servo-control caps. If not corrected this
condition could cause untimely
movements of servo-controls, which are
used on main and anti-torque rotors,
and lead to the loss of control of the
helicopter. 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
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.

Federal Register / Vol. 75, No. 51 / Wednesday, March 17, 2010 / Rules and Regulations
Relevant Service Information
Eurocopter has issued Alert Service
Bulletin (ASB) No. 67.00.37 for Model
AS 332 helicopters, ASB No. 67.00.40
for Model AS 350 helicopters, ASB No.
67.00.28 for Model AS 355 helicopters,
ASB No. 67.00.13 for Model AS 365 and
SA 365 helicopters, ASB No. 67.08 for
Model SA 366 helicopters, ASB No.
67A010 for Model EC 130 helicopters,
and ASB No. 67A010 for Model EC 155
helicopters, all Revision 0 and all dated
February 19, 2007. Two of the ASBs
have identical numbers and dates. There
is a separate ASB No. 67A010 with the
same date for the Model EC130
helicopter and the Model EC 155
helicopter. The actions described in the
MCAI AD are intended to correct the
same unsafe condition as that identified
in the service information.
wwoods2 on DSK1DXX6B1PROD with RULES_PART 1
Differences Between This AD and the
MCAI AD
We have reviewed the MCAI AD and
related service information and, in
general, agree with their substance.
However, our AD differs from the MCAI
AD in that it:
• Is not applicable to the Model AS
332 C1 helicopters because they are not
type certificated in the United States;
• Does not require returning the
servo-controls to the manufacturer;
• Does not address servo-control
‘‘spares’’ (parts not installed on a
helicopter);
• Uses the term ‘‘inspect’’ rather than
‘‘check’’; and
• Includes information explaining
that there are 2 ASBs with the same
number and date—ASB No. 67A010 for
the Model EC130 B4 helicopters and
ASB No. 67A010 for the Model EC 155B
and B1 helicopters.
Costs of Compliance
We estimate that this AD will affect
about 318 helicopters with 33 nonconforming control cap assemblies of
U.S. registry. Also, we estimate that it
would take about 1 work-hour to inspect
each helicopter in the fleet and 4 workhours per helicopter to remove and
replace an unairworthy servo-control.
The average labor rate is $85 per workhour. A replacement cap assembly
would cost $15,605. Based on these
figures, we estimate the cost of the AD
on U.S. operators to be $553,215, or
$1,740 per helicopter.
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
VerDate Nov<24>2008
14:47 Mar 16, 2010
Jkt 220001
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
product(s) 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.

Amendment 39–16231; Docket No.
FAA–2009–0663; Directorate Identifier
2007–SW–25–AD.
Effective Date
(a) This airworthiness directive (AD)
becomes effective on April 21, 2010.
Other Affected ADs
(b) None.
Applicability
(c) This AD applies to Eurocopter France
(Eurocopter) Model AS 332 C, L, L1, and L2;
AS 350 B3; AS355 F, F1, F2, and N; SA 365N
and N1; AS 365 N2 and N3; SA 366G1; EC
130 B4; and EC 155B and B1 helicopters,
certificated in any category.
Reason
(d) The mandatory continuing
airworthiness information (MCAI) AD states
that the AD is issued following a
manufacturing nonconformity found on one
batch of the servo-control cap, part number
(P/N) 800137. With a defective servo-control,
rotation of the distributor might not be
stopped mechanically since only friction of
inner seals holds the distributor sleeve in its
position. If not corrected this condition could
cause untimely movements of servo-controls,
which are used on main and anti-torque
rotors, and lead to the loss of control of the
helicopter.
Actions and Compliance
(e) Within 2 months after the effective date
of this AD, unless already done, do the
following actions.
(1) For each servo-control with a P/N and
a serial number (S/N) listed in paragraph
1.A.1. of the applicable Eurocopter Alert
Service Bulletin (ASB) stated in Table 1 of
this AD, determine whether there is a letter
‘‘R’’ marked in the inspection box of the
servo-control identification plate.
(2) If there is no letter ‘‘R’’ marked in the
inspection box of a servo-control
identification plate, on the next removal of
the servo-control, or not later than 2 years
after the effective date of this AD, whichever
occurs first, replace the servo-control with an
airworthy servo-control that has an ‘‘R’’
marked in the inspection box of the servocontrol identification plate or one with a
serial number not listed in paragraph 1.A.1
of the ASB applicable to your model
helicopter.
Note 1: The letter ‘‘R’’ marked in the
inspection box of the servo-control
identification plate indicates that the servocontrol cap assembly has been brought into
conformity with design data and has been
installed properly.
(3) There are 2 identically numbered and
dated ASBs. There is an ASB No. 67A010,
dated February 19, 2007, that applies to the
Model EC130B4 helicopters and an ASB No.
67A010, dated February 19, 2007, that
applies to the Model EC 155B and B1
helicopters. You must use the ASB that
applies to your model helicopter.

fluorescent penetrant inspection (FPI) of
the LPT stage 3 disk under certain
conditions and removal of the disk from
service before further flight if found
cracked. This AD also requires initial
and repetitive borescope inspections of
the high-pressure turbine (HPT) rotor
stage 1 and stage 2 blades for wear and
damage, including excessive airfoil
material loss. This AD results from three
reports of uncontained failures of LPT
stage 3 disks and eight reports of
cracked LPT stage 3 disks found during
shop visit inspections. We are issuing
this AD to prevent critical life-limited
rotating engine part failure, which could
result in an uncontained engine failure
and damage to the airplane.

38381). That NPRM proposed to address the unsafe condition created by a
manufacturing nonconformity found on one batch of servo-control caps.
If not corrected this condition could cause untimely movements of
servo-controls, which are used on main and anti-torque rotors, and lead
to the loss of control of the helicopter. 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 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.

Relevant Service Information
Eurocopter has issued Alert Service Bulletin (ASB) No. 67.00.37 for
Model AS 332 helicopters, ASB No. 67.00.40 for Model AS 350
helicopters, ASB No. 67.00.28 for Model AS 355 helicopters, ASB No.
67.00.13 for Model AS 365 and SA 365 helicopters, ASB No. 67.08 for
Model SA 366 helicopters, ASB No. 67A010 for Model EC 130 helicopters,
and ASB No. 67A010 for Model EC 155 helicopters, all Revision 0 and all
dated February 19, 2007. Two of the ASBs have identical numbers and
dates. There is a separate ASB No. 67A010 with the same date for the
Model EC130 helicopter and the Model EC 155 helicopter. 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
We have reviewed the MCAI AD and related service information and,
in general, agree with their substance. However, our AD differs from
the MCAI AD in that it:
Is not applicable to the Model AS 332 C1 helicopters
because they are not type certificated in the United States;
Does not require returning the servo-controls to the
manufacturer;
Does not address servo-control ``spares'' (parts not
installed on a helicopter);
Uses the term ``inspect'' rather than ``check''; and
Includes information explaining that there are 2 ASBs with
the same number and date--ASB No. 67A010 for the Model EC130 B4
helicopters and ASB No. 67A010 for the Model EC 155B and B1
helicopters.
Costs of Compliance
We estimate that this AD will affect about 318 helicopters with 33
non-conforming control cap assemblies of U.S. registry. Also, we
estimate that it would take about 1 work-hour to inspect each
helicopter in the fleet and 4 work-hours per helicopter to remove and
replace an unairworthy servo-control. The average labor rate is $85 per
work-hour. A replacement cap assembly would cost $15,605. Based on
these figures, we estimate the cost of the AD on U.S. operators to be
$553,215, or $1,740 per helicopter.
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 product(s) 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
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:
2010-06-07 Eurocopter France: Amendment 39-16231; Docket No. FAA-
2009-0663; Directorate Identifier 2007-SW-25-AD.
Effective Date
(a) This airworthiness directive (AD) becomes effective on April
21, 2010.
Other Affected ADs
(b) None.
Applicability
(c) This AD applies to Eurocopter France (Eurocopter) Model AS
332 C, L, L1, and L2; AS 350 B3; AS355 F, F1, F2, and N; SA 365N and
N1; AS 365 N2 and N3; SA 366G1; EC 130 B4; and EC 155B and B1
helicopters, certificated in any category.
Reason
(d) The mandatory continuing airworthiness information (MCAI) AD
states that the AD is issued following a manufacturing nonconformity
found on one batch of the servo-control cap, part number (P/N)
800137. With a defective servo-control, rotation of the distributor
might not be stopped mechanically since only friction of inner seals
holds the distributor sleeve in its position. If not corrected this
condition could cause untimely movements of servo-controls, which
are used on main and anti-torque rotors, and lead to the loss of
control of the helicopter.
Actions and Compliance
(e) Within 2 months after the effective date of this AD, unless
already done, do the following actions.
(1) For each servo-control with a P/N and a serial number (S/N)
listed in paragraph 1.A.1. of the applicable Eurocopter Alert
Service Bulletin (ASB) stated in Table 1 of this AD, determine
whether there is a letter ``R'' marked in the inspection box of the
servo-control identification plate.
(2) If there is no letter ``R'' marked in the inspection box of
a servo-control identification plate, on the next removal of the
servo-control, or not later than 2 years after the effective date of
this AD, whichever occurs first, replace the servo-control with an
airworthy servo-control that has an ``R'' marked in the inspection
box of the servo-control identification plate or one with a serial
number not listed in paragraph 1.A.1 of the ASB applicable to your
model helicopter.
Note 1: The letter ``R'' marked in the inspection box of the
servo-control identification plate indicates that the servo-control
cap assembly has been brought into conformity with design data and
has been installed properly.
(3) There are 2 identically numbered and dated ASBs. There is an
ASB No. 67A010, dated February 19, 2007, that applies to the Model
EC130B4 helicopters and an ASB No. 67A010, dated February 19, 2007,
that applies to the Model EC 155B and B1 helicopters. You must use
the ASB that applies to your model helicopter.
