Federal Register / Vol. 80, No. 23 / Wednesday, February 4, 2015 / Rules and Regulations
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.

SUPPLEMENTARY INFORMATION:
tkelley on DSK3SPTVN1PROD with RULES
Discussion
We issued a notice of proposed
rulemaking (NPRM) to amend 14 CFR
part 39 to supersede AD 2013–15–10,
Amendment 39–17526 (78 FR 54149,
September 3, 2013), (‘‘AD 2013–15–
10’’). AD 2013–15–10 applied to the
specified products. The NPRM
published in the Federal Register on
September 11, 2014 (79 FR 54220). The
NPRM proposed to retain the
requirements of AD 2013–15–10 for
inspecting the IPC rotor shaft rear
balance land for cracks. The NPRM also
proposed to require that the repetitive
in-shop eddy current inspections (ECIs)
in AD 2013–15–10 be performed even
after modifying certain engines. The
NPRM also proposed to eliminate
repetitive on-wing inspections for
certain other engines, and eliminate
certain in-shop visual inspections for all
engines.
Comments
We gave the public the opportunity to
participate in developing this AD. We
received no comments on the NPRM (79
FR 54220, September 11, 2014).

Costs of Compliance
We estimate that this AD will affect
about 136 engines installed on airplanes
of U.S. registry. We also estimate that it
will take about 14 hours per engine to
perform the inspections required by this
AD. The average labor rate is $85 per
hour. Replacement parts are estimated
to cost about $2,271 per engine. Based
on these figures, we estimate the cost of
the AD on U.S. operators to be $470,696.
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.

SUMMARY: We are superseding airworthiness directive (AD) 2013-15-10
that applies to certain Rolls-Royce plc (RR) RB211 turbofan engines. AD
2013-15-10 required inspecting the intermediate-pressure compressor
(IPC) rotor shaft rear balance land for cracks. This AD requires
inspecting the IPC rotor shaft rear balance land for cracks, eliminates
a terminating action, expands one inspection, and eliminates certain
other inspections. We are issuing this AD to detect cracking on the IPC
rotor shaft rear balance land, which could lead to uncontained engine
failure and damage to the airplane.

SUPPLEMENTARY INFORMATION:
Discussion
We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR
part 39 to supersede AD 2013-15-10, Amendment 39-17526 (78 FR 54149,
September 3, 2013), (``AD 2013-15-10''). AD 2013-15-10 applied to the
specified products. The NPRM published in the Federal Register on
September 11, 2014 (79 FR 54220). The NPRM proposed to retain the
requirements of AD 2013-15-10 for inspecting the IPC rotor shaft rear
balance land for cracks. The NPRM also proposed to require that the
repetitive in-shop eddy current inspections (ECIs) in AD 2013-15-10 be
performed even after modifying certain engines. The NPRM also proposed
to eliminate repetitive on-wing inspections for certain other engines,
and eliminate certain in-shop visual inspections for all engines.
Comments
We gave the public the opportunity to participate in developing
this AD. We received no comments on the NPRM (79 FR 54220, September
11, 2014).
Conclusion
We reviewed the available data and determined that air safety and
the public interest require adopting this AD as proposed except for
minor editorial changes, e.g., paragraph references and referencing the
latest version of certain service information incorporated by
reference.
Related Service Information
We reviewed RR Alert Non-Modification Service Bulletin (NMSB) No.
RB.211-72-AH059, dated December 11, 2012; RR Alert NMSB No. RB.211-72-
AH058, Revision 1, dated July 7, 2014; RR Alert NMSB No. RB.211-72-
AG270, Revision 4, dated March 21, 2011; RR Alert NMSB No. RB.211-72-
AG085, Revision 2, dated July 7, 2011; RR Alert NMSB No. RB.211-72-
AG264, Revision 5, dated March 21, 2011; and RR NMSB No. RB.211-72-
G448, Revision 4, dated August 21, 2014. The service information
describes procedures for performing borescope inspections and ECIs of
the IPC rotor shaft rear balance land. You can find this information in
the AD docket on the Internet at https://www.regulations.gov/#!docketBrowser;rpp=25;po=0;D=FAA-2007-28059.
Costs of Compliance
We estimate that this AD will affect about 136 engines installed on
airplanes of U.S. registry. We also estimate that it will take about 14
hours per engine to perform the inspections required by this AD. The
average labor rate is $85 per hour. Replacement parts are estimated to
cost about $2,271 per engine. Based on these figures, we estimate the
cost of the AD on U.S. operators to be $470,696.
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.
