Federal Register / Vol. 70, No. 121 / Friday, June 24, 2005 / Rules and 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 have 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 that this AD:
(1) Is not a ‘‘significant regulatory
action’’ under Executive Order 12866;
(2) Is not a ‘‘significant rule’’ under
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 a regulatory evaluation
of the estimated costs to comply with
this AD. See the ADDRESSES section for
a location to examine the regulatory
evaluation.

ACTION:
SUMMARY: The FAA is adopting a new
airworthiness directive (AD) for
Turbomeca S.A. Arriel 2B turboshaft
engines with Modification TU62A
incorporated. This AD results from
several reports of the hydromechanical
unit (HMU) acceleration controller axle
sticking. This AD requires initial and
repetitive inspections, cleaning,
lubrication, and checks for proper
operation of the HMU acceleration
controller axle. We are issuing this AD
to prevent loss of control of engine fuel
flow in manual control mode or mixed
control mode, leading to engine
overspeed and in-flight engine
shutdown, or uncommanded in-flight
engine shutdown.
DATES: Effective July 11, 2005. The
Director of the Federal Register
approved the incorporation by reference
of certain publications listed in the
regulations as of July 11, 2005.
We must receive any comments on
this AD by August 23, 2005.

SUPPLEMENTARY INFORMATION: The
Direction Generale de L’Aviation Civile
(DGAC), which is the airworthiness
authority for France, notified us that an
unsafe condition might exist on
Turbomeca S.A. Arriel 2B turboshaft
engines with Modification TU62A
incorporated. The DGAC advises that
VerDate jul<14>2003
16:42 Jun 23, 2005
Jkt 205001
several reports of the HMU acceleration
controller axle sticking have been
received that resulted in engine
overspeed and in-flight engine
shutdown, or uncommanded in-flight
engine shutdown. These events can
occur when the fuel system is either in
manual control mode or mixed control
mode. They are most likely to occur
during an HMU failure simulation or
during autorotation training. HMU
acceleration controller axle sticking can
result in an excessive decrease in engine
speed when the manual control is used
to reduce fuel flow. It can also result in
an excessive increase in engine speed
when moving the control back to the
flight notch. We are issuing this AD to
prevent loss of control of engine fuel
flow in the manual control mode or
mixed control mode, leading to engine
overspeed and in-flight engine
shutdown, or uncommanded in-flight
engine shutdown.
Relevant Service Information
We have reviewed and approved the
technical contents of Turbomeca Alert
Mandatory Service Bulletin (ASB) No.
A292 73 2814, Update No. 1, dated
January 11, 2005. That ASB describes
procedures for inspecting, lubricating,
and checking for proper operation of the
HMU acceleration controller axle. The
DGAC classified this service bulletin as
mandatory and issued AD F–2004–139,
dated August 18, 2004, in order to
ensure the airworthiness of these Arriel
2B turboshaft engines in France.
Bilateral Airworthiness Agreement
This Turbomeca Arriel 2B turboshaft
engine model is manufactured in
France. It is type certificated for
operation in the United States under the
provisions of section 21.29 of the
Federal Aviation Regulations (14 CFR
21.29) and the applicable bilateral
airworthiness agreement. Under this
bilateral airworthiness agreement, the
DGAC has kept the FAA informed of the
situation described above. We have
examined the findings of the DGAC,
reviewed all available information, and
determined that AD action is necessary
for products of this type design that are
certificated for operation in the United
States.
FAA’s Determination and Requirements
of This AD
The unsafe condition described
previously is likely to exist or develop
on other Turbomeca Arriel 2B
turboshaft engines of the same type
design. We are issuing this AD to
prevent loss of control of engine fuel
flow in the manual control mode or
mixed control mode, leading to engine

overspeed and in-flight engine
shutdown, or uncommanded in-flight
engine shutdown. This AD requires
initial and repetitive inspections,
cleaning, lubrication, and checks for
proper operation of the HMU
acceleration controller axle. You must
use the service information described
previously to perform the actions
required by this AD.
Since an unsafe condition exists that
requires the immediate adoption of this
AD, we have found that notice and
opportunity for public comment before
issuing this AD are impracticable. We
also found that good cause exists for
making this amendment effective in less
than 30 days.
Comments Invited

an existing airworthiness directive (AD)
for Eurocopter France (Eurocopter)
Model EC 155B, SA–365N and N1, AS–
365N2, and AS 365 N3 helicopters. That
AD currently requires inspecting the
hydraulic brake hose (hose) for crazing,
pinching, distortion, or leaks at the
torque link hinge and replacing the
hose, if necessary. That AD also requires
inspecting the hose and the emergency
flotation gear pipe to ensure adequate
clearance, and adjusting the landing
gear leg, if necessary. This amendment
requires the same actions as the existing
AD and adds another model helicopter
to the applicability. This amendment is
prompted by notification by the
manufacturer and the European
Authority that another affected model
helicopter, the Model EC155B1, may
have the same unsafe condition and
should be added to the existing AD. The
actions specified by this AD are
intended to prevent failure of a hose,

SUPPLEMENTARY INFORMATION: The Direction Generale de L'Aviation Civile
(DGAC), which is the airworthiness authority for France, notified us
that an unsafe condition might exist on Turbomeca S.A. Arriel 2B
turboshaft engines with Modification TU62A incorporated. The DGAC
advises that several reports of the HMU acceleration controller axle
sticking have been received that resulted in engine overspeed and in-
flight engine shutdown, or uncommanded in-flight engine shutdown. These
events can occur when the fuel system is either in manual control mode
or mixed control mode. They are most likely to occur during an HMU
failure simulation or during autorotation training. HMU acceleration
controller axle sticking can result in an excessive decrease in engine
speed when the manual control is used to reduce fuel flow. It can also
result in an excessive increase in engine speed when moving the control
back to the flight notch. We are issuing this AD to prevent loss of
control of engine fuel flow in the manual control mode or mixed control
mode, leading to engine overspeed and in-flight engine shutdown, or
uncommanded in-flight engine shutdown.
Relevant Service Information
We have reviewed and approved the technical contents of Turbomeca
Alert Mandatory Service Bulletin (ASB) No. A292 73 2814, Update No. 1,
dated January 11, 2005. That ASB describes procedures for inspecting,
lubricating, and checking for proper operation of the HMU acceleration
controller axle. The DGAC classified this service bulletin as mandatory
and issued AD F-2004-139, dated August 18, 2004, in order to ensure the
airworthiness of these Arriel 2B turboshaft engines in France.
Bilateral Airworthiness Agreement
This Turbomeca Arriel 2B turboshaft engine model is manufactured in
France. It is type certificated for operation in the United States
under the provisions of section 21.29 of the Federal Aviation
Regulations (14 CFR 21.29) and the applicable bilateral airworthiness
agreement. Under this bilateral airworthiness agreement, the DGAC has
kept the FAA informed of the situation described above. We have
examined the findings of the DGAC, reviewed all available information,
and determined that AD action is necessary for products of this type
design that are certificated for operation in the United States.
FAA's Determination and Requirements of This AD
The unsafe condition described previously is likely to exist or
develop on other Turbomeca Arriel 2B turboshaft engines of the same
type design. We are issuing this AD to prevent loss of control of
engine fuel flow in the manual control mode or mixed control mode,
leading to engine overspeed and in-flight engine shutdown, or
uncommanded in-flight engine shutdown. This AD requires initial and
repetitive inspections, cleaning, lubrication, and checks for proper
operation of the HMU acceleration controller axle. You must use the
service information described previously to perform the actions
required by this AD.
Since an unsafe condition exists that requires the immediate
adoption of this AD, we have found that notice and opportunity for
public comment before issuing this AD are impracticable. We also found
that good cause exists for making this amendment effective in less than
30 days.
Comments Invited
This AD is a final rule that involves requirements affecting flight
safety and was not preceded by notice and an opportunity for public
comment. However, we invite you to send us any written relevant data,
views, or arguments regarding this AD. Send your comments to an address
listed under ADDRESSES. Include ``AD Docket No. FAA-2005-21624;
Directorate Identifier 2005-NE-17-AD'' in the subject line of your
comments. We specifically invite comments on the overall regulatory,
economic, environmental, and energy aspects of the rule that might
suggest a need to modify it.
We will post all comments we receive, without change, to https://
dms.dot.gov, including any personal information you provide. We will
also post a report summarizing each substantive verbal contact with FAA
personnel concerning this AD. Using the search function of the DMS Web
site, anyone can find and read the comments in any of our dockets. The
Web site includes the name of the individual who sent the comment (or
signed the comment on behalf of an association, business, labor union,
etc.). You may review the DOT's complete Privacy Act Statement in the
Federal Register published on April 11, 2000 (65 FR 19477-78) or you
may visit https://dms.dot.gov.
Examining the AD Docket
You may examine the docket that contains the AD, any comments
received, and any final disposition in person at the DMS Docket Offices
between 9 a.m. and 5 p.m., Monday through Friday, except Federal
holidays. The Docket Office (telephone (800) 647-5227) is located on
the plaza level of the Department of Transportation Nassif Building at
the street address stated in ADDRESSES. Comments will be available
[[Page 36482]]
in the AD docket shortly after the DMS receives them.
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 have 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 that the regulation:
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 a summary of the costs to comply with this AD and
placed it in the AD Docket. You may get a copy of this summary by
sending a request to us at the address listed under ADDRESSES.
