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.

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 Action Labor cost Inspection ........................................................ 2.0 work-hours × $85 per hour = $170.00 .....

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 http://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

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:

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.

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.

(i) Installation Prohibition

    After the effective date of this AD, do not install an affected 
intermediate module on an engine unless the CIC has passed the 
inspection required by paragraph (g)(1) of this AD.

(j) Credit for Previous Actions

    You may take credit for the inspections and corrective action 
required by paragraph (g) of this AD, if you performed these actions 
before the effective date of this AD using RR Alert NMSB RB.211-72-
AH976, original issue, dated November 3, 2016 or RR Alert NMSB 
RB.211-72-AH976, Revision 1, dated November 17, 2016.

(k) Alternative Methods of Compliance (AMOCs)

    The Manager, Engine Certification Office, FAA, may approve AMOCs 
for this AD. Use the procedures found in 14 CFR 39.19 to make your 
request. You may email your request to: ANE-AD-AMOC@faa.gov.
