SUPPLEMENTARY INFORMATION:
Discussion
On May 22, 2012, at 77 FR 30232, the
Federal Register published our notice of
proposed rulemaking (NPRM), which
proposed to amend 14 CFR part 39 to
include an AD that would apply to
certain serial-numbered BHT Model
412, 412EP, and 412CF helicopters with
a collective lever, part number (P/N)
412–010–408–101. That NPRM
proposed to require within 25 hours
time-in-service (TIS) or 30 days,
whichever occurs first, and thereafter at
intervals not to exceed 100 hours TIS,
cleaning the collective lever and
inspecting it for cracks with a 10X or
higher power magnifying glass. If there
is a crack in the collective lever paint
finish, the NPRM proposed to require
removing the collective lever from the
swashplate and performing a fluorescent
penetrant inspection, and if there is a
crack in the collective lever, before
further flight, replacing the collective
lever with an airworthy collective lever.
The proposed requirements were
intended to detect a crack in the
collective lever, which could lead to
failure of the collective lever and
subsequent loss of control of the
helicopter.
Comments
We gave the public the opportunity to
participate in developing this AD, but
we did not receive any comments on the
NPRM (77 FR 30232, May 22, 2012).
FAA’s Determination
We have reviewed the relevant
information and determined that an
unsafe condition exists and is likely to
exist or develop on other products of
these same type designs and that air
safety and the public interest require
adopting the AD requirements as
proposed.
Related Service Information
We reviewed Bell Helicopter Alert
Service Bulletin (ASB) No. 412–11–148
and ASB No. 412CF–11–47, both
Revision A, and both dated December
12, 2011, which describe procedures for
repetitively inspecting the collective
lever with a magnifying glass and a
strong light source and, if necessary, a
fluorescent penetrant inspection. If
there is a crack, the ASBs require
replacing the collective lever.
E:\FR\FM\15NOR1.SGM
15NOR1
68056
Federal Register / Vol. 77, No. 221 / Thursday, November 15, 2012 / Rules and Regulations
Differences Between This AD and the
Service Information
The BHT ASBs require compliance
within 100 hours of flight time for the
initial inspection; this AD requires
compliance within 25 hours TIS or 30
days, whichever occurs first. If there is
a crack, the BHT ASBs require reporting
the defect to Bell Product Support
Engineering; this AD does not. The BHT
ASBs allow a portion of the collective
lever to be inspected by a mirror and
light only without a magnifying glass;
this AD requires using a 10X or higher
power magnifying glass for the entire
inspection.
Costs of Compliance
We estimate that this AD will affect
83 helicopters of U.S. Registry. We
estimate that operators may incur the
following costs in order to comply with
this AD. Inspecting the collective lever
requires one work-hour at an average
labor rate of $85 per work-hour, for a
cost per helicopter of $85 and a total
cost to the U.S. operator fleet of $7,055
per inspection cycle. Replacing a
cracked collective lever requires 10
work-hours at an average labor rate of
$85 per work-hour and required parts
will cost $12,883, for a total cost of
$13,733 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
products 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.
VerDate Mar<15>2010
13:24 Nov 14, 2012
Jkt 229001
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.

ACTION: Final rule.
AGENCY:
We are adopting a new
airworthiness directive (AD) for certain
Sikorsky Aircraft Corporation (Sikorsky)
Model S–76C helicopters. This AD
requires installing an improved throttle
stop and a wider trigger on the engine
control levers (ECL). This AD was
prompted by a bird-strike to the
windshield that resulted in unintended
movement of the engine control levers
from the forward position and towards
the flight-idle position, which reduced
power on both engines. These actions
are intended to prevent unintended
movement of the ECLs, resulting in
main rotor speed decay and subsequent
loss of control of the aircraft.

SUMMARY:
68057
Authority for This Rulemaking
On March 29, 2012, at 77 FR 18969,
the Federal Register published our
notice of proposed rulemaking (NPRM),
which proposed to amend 14 CFR part
39 to include an AD that would apply
to Sikorsky Model S–76C helicopters
with serial numbers 760506 and 760607
through 760812. That NPRM proposed
to require within 6 months after the
effective date of the AD, installing an
improved throttle stop and a wider
trigger on each ECL as specified in
Sikorsky Alert Service Bulletin (ASB)
No. 76–76–6A, Revision A, dated May
18, 2011.
The proposed requirements were
intended to prevent unintended in-flight
movement of the ECLs from the normal
‘‘FLY’’ position towards the ‘‘IDLE’’
position, which significantly reduces
engine power, resulting in an
unrecoverable loss of main rotor speed
and subsequent loss of control of the
helicopter.
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.
Comments
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;
Two commenters, one anonymous
and one from the National
Transportation Safety Board,
commented that they support the NPRM
(77 FR 18969, March 29, 2012).
FAA’s Determination
We have reviewed the relevant
information and determined that an
unsafe condition exists and is likely to
exist or develop on other products of the
same type design and that air safety and

Related Service Information
We reviewed ASB 76–76–6A, which
describes procedures for partially
disassembling the engine control
quadrant assembly, removing the
existing throttle stop, and installing a
new airworthy throttle stop. The ASB
also describes procedures to remove the
existing trigger assembly from each ECL
and install a new airworthy wide trigger
assembly.
Costs of Compliance
We estimate that this AD will affect
52 helicopters of U.S. Registry. We
estimate that operators may incur the
following costs in order to comply with
this AD. To replace the engine control
lever stop and trigger assemblies will
require 2 work-hours at an average labor
cost of $85 per hour. Required parts will
cost about $939. Based upon these costs,
we estimate a total cost of $1,109 per
helicopter and a total cost of $57,668 for
the entire U.S. operator fleet.

We have reviewed the relevant information and determined that an
unsafe condition exists and is likely to exist or develop on other
products of these same type designs and that air safety and the public
interest require adopting the AD requirements as proposed.
Related Service Information
We reviewed Bell Helicopter Alert Service Bulletin (ASB) No. 412-
11-148 and ASB No. 412CF-11-47, both Revision A, and both dated
December 12, 2011, which describe procedures for repetitively
inspecting the collective lever with a magnifying glass and a strong
light source and, if necessary, a fluorescent penetrant inspection. If
there is a crack, the ASBs require replacing the collective lever.
[[Page 68056]]
Differences Between This AD and the Service Information
The BHT ASBs require compliance within 100 hours of flight time for
the initial inspection; this AD requires compliance within 25 hours TIS
or 30 days, whichever occurs first. If there is a crack, the BHT ASBs
require reporting the defect to Bell Product Support Engineering; this
AD does not. The BHT ASBs allow a portion of the collective lever to be
inspected by a mirror and light only without a magnifying glass; this
AD requires using a 10X or higher power magnifying glass for the entire
inspection.
Costs of Compliance
We estimate that this AD will affect 83 helicopters of U.S.
Registry. We estimate that operators may incur the following costs in
order to comply with this AD. Inspecting the collective lever requires
one work-hour at an average labor rate of $85 per work-hour, for a cost
per helicopter of $85 and a total cost to the U.S. operator fleet of
$7,055 per inspection cycle. Replacing a cracked collective lever
requires 10 work-hours at an average labor rate of $85 per work-hour
and required parts will cost $12,883, for a total cost of $13,733 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 products 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.
