AGENCY:
SUMMARY: The FAA is adopting a new
airworthiness directive (AD) for
Turbomeca Arrius 2 F turboshaft
engines. This AD requires removing
from service certain serial number (SN)
fuel control units (FCUs) or replacing
the constant delta pressure diaphragm
in those FCUs. This AD results from a
report of an accident in July 2005
involving a Eurocopter EC120B
helicopter. We are issuing this AD to
prevent an uncommanded engine inflight shutdown on a single-engine
helicopter, resulting in a forced
autorotation landing or an accident.
DATES: Effective October 3, 2005. The
Director of the Federal Register
approved the incorporation by reference
of certain publications listed in the
regulations as of October 3, 2005.
We must receive any comments on
this AD by November 15, 2005.

The
Direction Generale de L’Aviation Civile
(DGAC), which is the airworthiness
authority for France, notified the FAA
that an unsafe condition may exist on
Turbomeca Arrius 2 F turboshaft
engines. The DGAC advises that a
Eurocopter EC120B helicopter powered
by an Arrius 2 F turboshaft engine
experienced an uncommanded in-flight
engine shutdown. An increase in fuel
flow led to an increase in gas generator
and power turbine speeds. Turbine
blades separated from the disk due to
the overspeed. Turbomeca determined
that the fuel flow increase was caused
by an improperly assembled and
subsequent failure of the constant delta
pressure (delta P) diaphragm in the
FCU. Only certain types of constant
delta P diaphragms have been identified
as being capable of being improperly
assembled. Engine serial numbers that
may have this type of constant delta P
diaphragm are listed in Turbomeca
Alert Mandatory Service Bulletin (MSB)
No. A319 73 4825, dated August 3,
2005. The manufacturer is making spare
FCUs available as fast as possible and
has established a rotable pool of spares.
After we reviewed the Turbomeca SB,
we concluded that using the Turbomeca
rotable pool of spares as soon as
practicable effectively manages the risk
of another failure of the uninspected
engine population. To this end, we are
requiring that FCUs identified in the
Turbomeca SB be replaced as soon as
practicable but not to exceed February
28, 2006. Because the practicable
compliance time may be quite short for
some operators and the rotable pool
requires consistent participation, we are
issuing this AD as final rule; request for
comments.
SUPPLEMENTARY INFORMATION:
Relevant Service Information
We have reviewed and approved the
technical contents of Turbomeca Alert
MSB No. A319 73 4825, dated August
3, 2005. That MSB lists the affected
FCUs by SN and describes procedures
for removing affected FCUs from service
or replacing constant delta P
diaphragms in those FCUs. The DGAC
classified this service bulletin as
mandatory and issued AD No. F–2005–
143, dated August 17, 2005, and AD No.
F–2005–143 R1, dated August 31, 2005,
in order to ensure the airworthiness of
these Arrius 2 F turboshaft engines in
France.

Federal Register / Vol. 70, No. 179 / Friday, September 16, 2005 / Rules and Regulations
Bilateral Airworthiness Agreement
This engine model is manufactured in
France and 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 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 Arrius 2 F
turboshaft engines of the same type
design. We are issuing this AD to
prevent an uncommanded engine inflight shutdown on a single-engine
helicopter, resulting in a forced
autorotation landing or an accident.
This AD requires removing from service
certain SN FCUs or replacing the
constant delta P diaphragm in those
FCUs. You must use the service
information described previously to
perform the actions required by this AD.
FAA’s Determination of the Effective
Date
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, and
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

List of Subjects in 14 CFR Part 39
Air transportation, Aircraft, Aviation
safety, Incorporation by reference,
Safety.
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:

SUPPLEMENTARY INFORMATION: This
amendment to Title 14 of the Code of
Federal Regulations, Part 97 (14 CFR
part 97), establishes, amends, suspends,
or revokes SIAPs and/or Weather
Takeoff Minimums. The complete
regulatory description of each SIAP
and/or Weather Takeoff Minimums is
contained in official FAA form
documents which are incorporated by
reference in this amendment under 5
U.S.C. 552(a), 1 CFR part 51, and 14
CFR part 97.20. The applicable FAA
Forms are identified as FAA Forms
8260–3, 8260–4, 8260–5 and 8260–15A.
Materials incorporated by reference are
available for examination or purchase as
stated above.
The large number of SIAPs and/or
Weather Takeoff Minimums, their
complex nature, and the need for a
special format make their verbatim
publication in the Federal Register
expensive and impractical. Further,
airmen do not use the regulatory text of
the SIAPs and/or Weather Takeoff
Minimums but refer to their depiction
on charts printed by publishers of
aeronautical materials. Thus, the
advantages of incorporation by reference
are realized and publication of the
complete description of each SIAP and/
or Weather Takeoff Minimums
contained in FAA form documents is
unnecessary. The provisions of this
amendment state the affected CFR
sections, with the types and effective
dates of the SIAPs and/or Weather
Takeoff Minimums. This amendment
also identifies the airport, its location,
the procedure identification and the
amendment number.
The Rule
This amendment to 14 CFR part 97 is
effective upon publication of each
separate SIAP and/or Weather Takeoff
Minimums as contained in the
transmittal. Some SIAP and/or Weather
Takeoff Minimums amendments may
have been previously issued by the FAA
in a Flight Data Center (FDC) Notice to
Airmen (NOTAM) as an emergency
action of immediate flight safety relating
directly to published aeronautical
charts. The circumstances which
created the need for some SIAP, and/or
Weather Takeoff Minimums
amendments may require making them
effective in less than 30 days. For the

affected FCUs by SN and describes procedures for removing affected FCUs
from service or replacing constant delta P diaphragms in those FCUs.
The DGAC classified this service bulletin as mandatory and issued AD
No. F-2005-143, dated August 17, 2005, and AD No. F-2005-143 R1, dated
August 31, 2005, in order to ensure the airworthiness of these Arrius 2
F turboshaft engines in France.
[[Page 54623]]
Bilateral Airworthiness Agreement
This engine model is manufactured in France and 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 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 Arrius 2 F turboshaft engines of the same
type design. We are issuing this AD to prevent an uncommanded engine
in-flight shutdown on a single-engine helicopter, resulting in a forced
autorotation landing or an accident. This AD requires removing from
service certain SN FCUs or replacing the constant delta P diaphragm in
those FCUs. You must use the service information described previously
to perform the actions required by this AD.
FAA's Determination of the Effective Date
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, and 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-2005-22430;
Directorate Identifier 2005-NE-34-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,
including 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

Examining the AD Docket
You may examine the docket that contains the AD, any comments
received, and any final disposition in person at the Docket Management
Facility 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 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.
