Discussion
The European Aviation Safety Agency
(EASA), which is the Technical Agent
for the Member States of the European
Community, has issued EASA AD 2017–
0071, dated April 26, 2017 (referred to
hereinafter as ‘‘the MCAI’’), to correct an
unsafe condition for the specified
products. The MCAI states:
Comments Invited
It has been determined that certain
compressor intermediate cases (CIC),
repaired by RR Repair FRSC005, have a
higher probability of cracking, due to
increased residual stresses which were
applied during the weld repair process. This
condition, if not detected and corrected,
could lead to CIC failure, possibly resulting
in damage to, and/or reduced control of, the
aeroplane. To address this potential unsafe
condition, RR released Alert NonModification Service Bulletin (NMSB)
RB.211–72–AH976, later revised, providing
inspection instructions. For the reason
described above, this AD requires a one-time
fluorescent-penetrant inspection (FPI) of each
affected CIC and, depending on findings,
accomplishment of a repair.
This AD is a final rule that involves
requirements affecting flight safety, and
we did not precede it by notice and
You may obtain further information
by examining the MCAI in the AD
docket on the Internet at https://
www.regulations.gov by searching for
and locating Docket No. FAA–2017–
0114.
Related Service Information Under 1
CFR Part 51
RR has issued Alert NMSB RB.211–
72–AH976, Revision 2, dated March 16,
2017. The Alert NMSB describes
procedures for FPI of the CIC that have
RR Repair FRSC005 applied to them.
This service 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.
FAA’s Determination and Requirements
of This AD
This product has been approved by
the aviation authority of the United
Kingdom, and is approved for operation
in the United States. Pursuant to our
bilateral agreement with the European
Community, EASA has notified us of
the unsafe condition described in the
MCAI and service information
referenced above. 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
products of the same type design. This
AD requires one-time FPI of each
affected CIC and, depending on
findings, accomplishment of a repair.
FAA’s Determination of the Effective
Date
No domestic operators use this
product. Therefore, we find that notice
and opportunity for prior public
comment are unnecessary and that good
cause exists for making this amendment
effective in less than 30 days.
Costs of Compliance
We estimate that this AD affects 0
engines installed on airplanes of U.S.
registry.
We estimate the following costs to
comply with this AD:

Regulatory Findings
(e) Reason
This AD was prompted by CICs that were
weld repaired and have a higher probability
of cracking due to increased residual stresses
as a result of the weld repair process. We are
issuing this AD to prevent CIC failure, engine
separation and loss of the airplane.
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:
(1) Is not a ‘‘significant regulatory
action’’ under Executive Order 12866,
(2) Is not a ‘‘significant rule’’ under
the 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.

Discussion
The European Aviation Safety Agency (EASA), which is the Technical
Agent for the Member States of the European Community, has issued EASA
AD 2017-0071, dated April 26, 2017 (referred to hereinafter as ``the
MCAI''), to correct an unsafe condition for the specified products. The
MCAI states:
It has been determined that certain compressor intermediate
cases (CIC), repaired by RR Repair FRSC005, have a higher
probability of cracking, due to increased residual stresses which
were applied during the weld repair process. This condition, if not
detected and corrected, could lead to CIC failure, possibly
resulting in damage to, and/or reduced control of, the aeroplane. To
address this potential unsafe condition, RR released Alert Non-
Modification Service Bulletin (NMSB) RB.211-72-AH976, later revised,
providing inspection instructions. For the reason described above,
this AD requires a one-time fluorescent-penetrant inspection (FPI)
of each affected CIC and, depending on findings, accomplishment of a
repair.
You may obtain further information by examining the MCAI in the AD
docket on the Internet at https://www.regulations.gov by searching for
and locating Docket No. FAA-2017-0114.
Related Service Information Under 1 CFR Part 51
RR has issued Alert NMSB RB.211-72-AH976, Revision 2, dated March
16, 2017. The Alert NMSB describes procedures for FPI of the CIC that
have RR Repair FRSC005 applied to them. This service 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.
FAA's Determination and Requirements of This AD
This product has been approved by the aviation authority of the
United Kingdom, and is approved for operation in the United States.
Pursuant to our bilateral agreement with the European Community, EASA
has notified us of the unsafe condition described in the MCAI and
service information referenced above. 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 products of
the same type design. This AD requires one-time FPI of each affected
CIC and, depending on findings, accomplishment of a repair.
FAA's Determination of the Effective Date
No domestic operators use this product. Therefore, we find that
notice and opportunity for prior public comment are unnecessary and
that good cause exists for making this amendment effective in less than
30 days.
Costs of Compliance
We estimate that this AD affects 0 engines installed on airplanes
of U.S. registry.
We estimate the following costs to comply with this AD:
Estimated Costs
----------------------------------------------------------------------------------------------------------------
Cost per Cost on U.S.

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
[[Page 24035]]
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:
(1) Is not a ``significant regulatory action'' under Executive
Order 12866,
(2) Is not a ``significant rule'' under the 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.
List of Subjects in 14 CFR Part 39

Adoption of the Amendment
Accordingly, under the authority delegated to me by the
Administrator, the FAA amends 14 CFR part 39 as follows:
PART 39--AIRWORTHINESS DIRECTIVES
0
1. The authority citation for part 39 continues to read as follows:
Authority: 49 U.S.C. 106(g), 40113, 44701.
Sec. 39.13 [Amended]
0
2. The FAA amends Sec. 39.13 by adding the following new airworthiness
directive (AD):
2017-10-06 Rolls-Royce plc: Amendment 39-18880; Docket No. FAA-2017-
0114; Directorate Identifier 2017-NE-03-AD.
(a) Effective Date
This AD is effective June 9, 2017.
(b) Affected ADs
None.
(c) Applicability
This AD applies to Rolls-Royce plc (RR) RB211 Trent 768-60,
RB211 Trent 772-60, and RB211 Trent 772B-60 turbofan engines that
have a compressor intermediate case (CIC) that was repaired using RR
Repair FRSC005.
(d) Subject
Joint Aircraft System Component (JASC) 7230, Turbine Engine
Compressor Section.
(e) Reason
This AD was prompted by CICs that were weld repaired and have a
higher probability of cracking due to increased residual stresses as
a result of the weld repair process. We are issuing this AD to
prevent CIC failure, engine separation and loss of the airplane.
(f) Compliance
Comply with this AD within the compliance times specified,
unless already done.
(g) Required Actions
(1) Inspect repaired CICs during the next shop visit, or within
6,000 engine flight cycles, whichever occurs first, after the
effective date of this AD, using paragraph 3.B.(1)(c) of the
Accomplishment Instructions, of RR Alert Non-Modification Service
Bulletin (NMSB) RB.211-72-AH976, Revision 2, dated March 16, 2017.
(2) If a CIC fails inspection required by paragraph (g)(1) of
this AD, either repair the CIC using paragraph 3.B.(2)(b) of the
Accomplishment Instructions, of RR Alert NMSB RB.211-72-AH976,
Revision 2, dated March 16, 2017, or, replace the CIC with a part
eligible for installation, before next flight.
(h) Definitions
For the purpose of this AD, a shop visit is the induction of an
engine into the shop for maintenance or overhaul that requires the
separation of major mating engine module flanges. The separation of
engine flanges solely for the purpose of transporting the engine
without subsequent engine maintenance does not constitute an engine
shop visit.
