rotating star, part number (P/N)
341A31.4116.21, installed on Model
SA341G helicopters.
Comments
We gave the public the opportunity to
participate in developing this AD, but
we did not receive any comments on the
NPRM.
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, DGAC, its
technical representative, has notified us
of the unsafe condition described in the
DGAC AD. We are issuing this AD
because we evaluated all information
provided by DGAC and determined the
unsafe condition exists and is likely to
exist or develop on other helicopters of
the same type designs and that air safety
and the public interest require adopting
the AD requirements as proposed.
wreier-aviles on DSK5TPTVN1PROD with RULES
Costs of Compliance
We estimate that this AD will affect
21 helicopters of U.S. registry and the
actions will take approximately 6 work
hours per helicopter to accomplish at an
average labor rate of $85 per work hour.
Required parts will cost approximately
$6,000. Based on these figures, we
estimate the total cost impact of this AD
on U.S. operators to be $6,510 to replace
the rotating star on each helicopter, or
$136,710 for the entire U.S. 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
VerDate Mar<15>2010

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
wreier-aviles on DSK5TPTVN1PROD with RULES
We issued a notice of proposed
rulemaking (NPRM) to amend 14 CFR
part 39 to include an AD that would
apply to the specified products. That
NPRM was published in the Federal
Register on February 24, 2012 (77 FR
11019). That NPRM proposed to correct
an unsafe condition for the specified
products. European Aviation Safety
Agency (EASA) AD 2011–0232 states:
Several LP compressor booster rotors have
been found non-compliant to original design.
The technical investigations carried out by
Rolls-Royce Deutschland revealed that this
discrepancy is due to a manufacturing defect
and that only some specific LP compressor
booster rotor serial numbers are affected.
This condition, if not corrected, could lead
to an uncontained engine failure, potentially
damaging the aeroplane and injuring its
occupants, and/or injuring persons on the
ground.
To address this condition, RRD has
developed an inspection program and a
rework for the affected LP compressor
booster rotors.
For the reason described above, depending
on engine type of operations, this AD
VerDate Mar<15>2010
14:15 Sep 13, 2012
Jkt 226001
requires repetitive fluorescent penetrant
inspections of the LP compressor booster
rotor and if any crack is found, replacement
with a serviceable part. This AD also requires
rework of all affected LP compressor booster
rotors.
You may obtain further information by
examining EASA AD 2011–0232 in the
AD docket.
Comments
We gave the public the opportunity to
participate in developing this AD. We
received no comments on the NPRM.
Conclusion
We reviewed the available data and
determined that air safety and the
public interest require adopting the AD
as proposed.
Costs of Compliance
Based on the service information, we
estimate that this AD affects about 96
engines installed on airplanes of U.S.
registry. We also estimate that it will
take about 5 work-hours per engine to
perform one inspection and about 8
work-hours per engine to perform the
rework. The average labor rate is $85 per
work-hour. Based on these figures, if all
engines are reworked, we estimate the
cost of the AD on U.S. operators to
perform one inspection and to perform
the rework to be $106,080.
Authority for This Rulemaking
Title 49 of the United States Code

Comments
We gave the public the opportunity to participate in developing
this AD. We received no comments on the NPRM.
Conclusion
We reviewed the available data and determined that air safety and
the public interest require adopting the AD as proposed.
Costs of Compliance
Based on the service information, we estimate that this AD affects
about 96 engines installed on airplanes of U.S. registry. We also
estimate that it will take about 5 work-hours per engine to perform one

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

We are issuing this rulemaking under the authority described in
``Subtitle VII, Part A, Subpart III, Section 44701: General

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 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 this AD:
