SUPPLEMENTARY INFORMATION:
Discussion
On September 15, 2014, at 79 FR
54925, the Federal Register published
our notice of proposed rulemaking
(NPRM), which proposed to amend 14
CFR part 39 by adding an AD that
would apply to Airbus Helicopters
Model AS355E, AS355F, AS355F1, and
AS355F2 helicopters with a certain
flowmeter installed. The NPRM
proposed to require, within 750 hours
time-in-service, removing the flowmeter
from each engine, replacing the fuel
hose with part number (P/N) 704A34–
416–029 for the left-hand (LH) engine
and P/N 704A34–416–030 for the righthand (RH) engine, removing the
flowmeter indicator, and disabling the
flowmeter electrical connections. The
proposed requirements were intended to
prevent obstruction of the fuel supply to
the flowmeter, which could result in
engine flame-out and subsequent loss of
control of the helicopter.
The NPRM was prompted by AD No.
2013–0205, dated September 9, 2013,
issued by EASA, which is the Technical
Agent for the Member States of the
European Union, to correct an unsafe
condition for Eurocopter (now Airbus
Helicopters) Model AS355 E, AS355 F,
AS355 F1, and AS355 F2 helicopters
with modification 350A070791
(installation of the Fueltron flowmeter),
except helicopters with modification
355A085801 (removal of the Fueltron
flowmeter). EASA advises, after landing,
an AS355 helicopter experienced an
uncontrolled flame-out of the No. 1
engine caused by particle contamination
in the fuel that obstructed the Fueltron
flowmeter. EASA further states that
because the flowmeter installation is
identical on both engines, this condition
could lead to flame-out of both engines
in flight, possibly resulting in reduced
control of the helicopter. EASA AD No.
2013–0205 requires removing the
E:\FR\FM\09JNR1.SGM
09JNR1
Federal Register / Vol. 80, No. 110 / Tuesday, June 9, 2015 / Rules and Regulations
flowmeter from each engine, modifying
the fuel line system with new fuel lines,
removing the flowmeter indicator, and
disabling the flowmeter electrical
connections. Since we issued the NPRM
(79 FR 54925, September 15, 2014), the
title of the approving official for
Alternative Methods of Compliance
(AMOCs) has changed. Thus, we have
revised the title of the approving official
from the Manager of the Regulations and
Policy Group to the Manager of the
Safety Management Group.
Comments
We gave the public the opportunity to
participate in developing this AD, but
we did not receive any comments on the
NPRM (79 FR 54925, September 15,
2014).
FAA’s Determination
These helicopters have been approved
by the aviation authority of France and
are approved for operation in the United
States. Pursuant to our bilateral
agreement with France, EASA, its
technical representative, has notified us
of the unsafe condition described in the
EASA AD. We are issuing this AD
because we evaluated all information
provided by EASA and determined the
unsafe condition exists and is likely to
exist or develop on other helicopters of
these same type designs and that air
safety and the public interest require
adopting the AD requirements as
proposed.
tkelley on DSK3SPTVN1PROD with RULES
Interim Action
We consider this AD to be an interim
action. The design approval holder is
currently developing a modification that
will address the unsafe condition
identified in this AD. Once this
modification is developed, approved,
and available, we might consider
additional rulemaking.
Related Service Information Under 1
CFR Part 51
Eurocopter issued Alert Service
Bulletin (ASB) No. AS355–28.00.20,
Revision 0, dated June 6, 2013, for
Model AS355 E, AS355 F, AS355 F1,
and AS355 F2 helicopters, which
describes procedures for removing and
disabling the Fueltron flowmeter
installation. The ASB corresponds to
Eurocopter modification 355A085801.
This information is reasonably available
because the interested parties have
access to it through their normal course
of business or by the means identified
in the ADDRESSES section of this AD.
Costs of Compliance
We estimate that this AD will affect
47 helicopters of U.S. Registry. We
VerDate Sep<11>2014
15:56 Jun 08, 2015
Jkt 235001
estimate that operators may incur the
following costs in order to comply with
this AD. At an average labor rate of $85
per work-hour, removing the flowmeter
installation requires about 4 workhours, and required parts cost about
$1,600, for a cost per helicopter of
$1,940 and a total cost of $91,180 for the
fleet.
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
helicopters identified in this rulemaking
action.
Regulatory Findings
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);
(3) Will not affect intrastate aviation
in Alaska to the extent that it justifies
making a regulatory distinction; and
(4) 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.

SUPPLEMENTARY INFORMATION:
Discussion
On June 7, 2013, at 78 FR 34282, the
Federal Register published our notice of
proposed rulemaking (NPRM), which
proposed to amend 14 CFR part 39 by
adding an AD that would apply to
certain Bell Model 206L–3 and 206L–4
helicopters. The NPRM proposed to
require installing a placard on the
instrument panel below the dual
tachometer and revising the Operating
Limitations section of the Model 206L–
3 and 206L–4 RFMs by inserting pages
that limit steady-state operations
between speeds of 71.8% and 91.5%.
The proposed requirements were
intended to prevent turbine failure,
engine power loss, and subsequent loss
of control of the helicopter.
The NPRM was prompted by TCCA
AD No. CF–2005–28R1, dated June 14,
2007, to correct an unsafe condition for
certain Model 206L–3 and 206L–4
helicopters. TCCA, which is the aviation
authority for Canada, advises of several
failures of third stage turbine wheels
used in Rolls-Royce 250–C30S and 250–
C47B engines. According to TCCA,
Rolls-Royce determined that detrimental
vibrations can occur within a particular
range of turbine speeds, and may be a
contributing factor to these failures. Bell
has revised the RFM and provided a
corresponding decal to inform pilots to
avoid steady-state operations between
71.8% and 91.5% turbine speeds. The
TCCA AD requires amending the RFMs,
advising pilots of the change, and
installing a decal as described in Bell
Alert Service Bulletin (ASB) No. 206L–
05–134, dated June 8, 2005, or later
revisions.
On October 3, 2014, at 79 FR 59695,
the Federal Register published our
supplemental notice of proposed
rulemaking (SNPRM), which proposed
to revise the applicability and change
the procedures for updating the RFM.
The SNPRM proposed adding Bell
Model 206L–1 helicopters with Engine
Upgrade Kit part number (P/N) 206–
706–520 installed, to the applicability.
Engine Upgrade Kit P/N 206–706–520
replaces the Rolls-Royce 250–C28B
engine with a Rolls-Royce 250–C30P
engine. The condition causing the
failures of third stage turbine wheels
used in Rolls-Royce 250–C30S and 250–
C–47B engines could also exist in RollsRoyce 250–C30P engines. The SNPRM

On September 15, 2014, at 79 FR 54925, the Federal Register
published our notice of proposed rulemaking (NPRM), which proposed to
amend 14 CFR part 39 by adding an AD that would apply to Airbus
Helicopters Model AS355E, AS355F, AS355F1, and AS355F2 helicopters with
a certain flowmeter installed. The NPRM proposed to require, within 750
hours time-in-service, removing the flowmeter from each engine,
replacing the fuel hose with part number (P/N) 704A34-416-029 for the
left-hand (LH) engine and P/N 704A34-416-030 for the right-hand (RH)
engine, removing the flowmeter indicator, and disabling the flowmeter
electrical connections. The proposed requirements were intended to
prevent obstruction of the fuel supply to the flowmeter, which could
result in engine flame-out and subsequent loss of control of the
helicopter.
The NPRM was prompted by AD No. 2013-0205, dated September 9, 2013,
issued by EASA, which is the Technical Agent for the Member States of
the European Union, to correct an unsafe condition for Eurocopter (now
Airbus Helicopters) Model AS355 E, AS355 F, AS355 F1, and AS355 F2
helicopters with modification 350A070791 (installation of the Fueltron
flowmeter), except helicopters with modification 355A085801 (removal of
the Fueltron flowmeter). EASA advises, after landing, an AS355
helicopter experienced an uncontrolled flame-out of the No. 1 engine
caused by particle contamination in the fuel that obstructed the
Fueltron flowmeter. EASA further states that because the flowmeter
installation is identical on both engines, this condition could lead to
flame-out of both engines in flight, possibly resulting in reduced
control of the helicopter. EASA AD No. 2013-0205 requires removing the
[[Page 32457]]
flowmeter from each engine, modifying the fuel line system with new
fuel lines, removing the flowmeter indicator, and disabling the
flowmeter electrical connections. Since we issued the NPRM (79 FR
54925, September 15, 2014), the title of the approving official for
Alternative Methods of Compliance (AMOCs) has changed. Thus, we have
revised the title of the approving official from the Manager of the
Regulations and Policy Group to the Manager of the Safety Management
Group.
Comments
We gave the public the opportunity to participate in developing
this AD, but we did not receive any comments on the NPRM (79 FR 54925,
September 15, 2014).
FAA's Determination
These helicopters have been approved by the aviation authority of
France and are approved for operation in the United States. Pursuant to
our bilateral agreement with France, EASA, its technical
representative, has notified us of the unsafe condition described in
the EASA AD. We are issuing this AD because we evaluated all
information provided by EASA and determined the unsafe condition exists
and is likely to exist or develop on other helicopters of these same
type designs and that air safety and the public interest require
adopting the AD requirements as proposed.
Interim Action
We consider this AD to be an interim action. The design approval
holder is currently developing a modification that will address the
unsafe condition identified in this AD. Once this modification is
developed, approved, and available, we might consider additional
rulemaking.
Related Service Information Under 1 CFR Part 51
Eurocopter issued Alert Service Bulletin (ASB) No. AS355-28.00.20,
Revision 0, dated June 6, 2013, for Model AS355 E, AS355 F, AS355 F1,
and AS355 F2 helicopters, which describes procedures for removing and
disabling the Fueltron flowmeter installation. The ASB corresponds to
Eurocopter modification 355A085801. This information is reasonably
available because the interested parties have access to it through
their normal course of business or by the means identified in the
ADDRESSES section of this AD.
Costs of Compliance
We estimate that this AD will affect 47 helicopters of U.S.
Registry. We estimate that operators may incur the following costs in
order to comply with this AD. At an average labor rate of $85 per work-
hour, removing the flowmeter installation requires about 4 work-hours,
and required parts cost about $1,600, for a cost per helicopter of
$1,940 and a total cost of $91,180 for the fleet.
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 helicopters identified in this
rulemaking action.
Regulatory Findings
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);
(3) Will not affect intrastate aviation in Alaska to the extent
that it justifies making a regulatory distinction; and
(4) 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.
