Airworthiness Directives; Turbomeca

Federal Aviation
Administration (FAA), DOT.
ACTION: Final rule.
AGENCY:
We are superseding an
existing airworthiness directive (AD) for
all Turbomeca S.A. Arriel 1E2, 1S, and
1S1 turboshaft engines. That AD
currently requires a one-time inspection
and torque check of the 3-way union
plug installed on all fuel control units
(FCUs). This new AD requires the same
actions. This AD also requires reduction
of the applicability to certain FCUs and
references an updated service bulletin
containing additional detailed
information to identify the noncompliant ‘‘red disk.’’ This AD also
requires replacement of the plug before
further flight if it is found to be noncompliant, and prohibits installation of
FCUs that have not passed the 3-way
union plug inspection and torque check.
This AD was prompted by Turbomeca
S.A. informing us that FCUs
manufactured, repaired, or overhauled
after March 31, 2008, do not require
inspection. We are issuing this AD to
prevent fuel leaks, which could result in
a fire and damage to the helicopter.
DATES: This AD is effective January 7,
2013.
The Director of the Federal Register
approved the incorporation by reference
of a certain publication listed in the AD
as of January 7, 2013.

SUPPLEMENTARY INFORMATION:
Discussion
We issued a notice of proposed
rulemaking (NPRM) to amend 14 CFR
part 39 to supersede AD 2009–03–04,
Amendment 39–15805 (74 FR 7796,
February 20, 2009). That AD applies to
the specified products. The NPRM
published in the Federal Register on
July 25, 2012 (77 FR 43552). That NPRM
proposed to require a one-time
inspection and torque check of the 3way union plug, replacement of the plug
before further flight if it is found to be
non-compliant, and would prohibit
installation of FCUs that have not
passed the 3-way union plug inspection
and torque check.
Comments
We gave the public the opportunity to
participate in developing this AD. We
received no comments on the NPRM.
Conclusion
We reviewed the relevant data and
determined that air safety and the
public interest require adopting the AD
as proposed.
Costs of Compliance
Based on the updated service
information, we estimate that this AD
will affect about 179 engines installed
on helicopters of U.S. registry. We also
estimate that it will take about 0.5 hour
per product to comply with this AD.
The average labor rate is $85 per hour.
Required parts will cost about $14 per
product. Based on these figures, we
estimate the cost of the AD on U.S.
operators to be $10,114. Our cost
estimate is exclusive of possible
warranty coverage.
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
E:\FR\FM\03DER1.SGM
03DER1
71492
Federal Register / Vol. 77, No. 232 / Monday, December 3, 2012 / Rules and Regulations
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.
2012–23–12 Turbomeca S.A.: Amendment
39–17268; Docket No. FAA–2008–0681;
Directorate Identifier 2008–NE–13–AD.
Regulatory Findings
Turbomeca S.A. informed the European
Aviation Safety Agency of a case of a ‘‘red
disk’’ plug, adapted for bench testing, which
was installed on the FCU on an engine and
released for service operation. An engine
experienced an in-service high pressure leak
event (at the fuel pump outlet) due to
cracking of this ‘‘red disk’’ plug. This leak
could lead to in-flight flame-out and/or
possibly a fire. This AD was prompted by
Turbomeca S.A. informing us that FCUs
manufactured, repaired, or overhauled after
March 31, 2008, do not require inspection.
We are issuing this AD to prevent fuel leaks,
which could result in a fire and damage to
the helicopter.
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),
(3) Will not affect intrastate aviation
in Alaska, 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.
