Discussion We issued AD 2016–03–03, Amendment 39–18390 (81 FR 12585, March 10, 2016), ‘‘AD 2016–03–03,’’ for all RR Viper Mk. 521, Viper Mk. 522, and Viper Mk. 601–22 turbojet engines. AD 2016–03–03 requires reducing the life of certain critical parts. AD 2016– 03–03 resulted from a determination by RR that the life of certain critical engine parts needed to be reduced. We issued AD 2016–03–03 to prevent failure of life-limited parts, which could lead to an uncontained part release, damage to the engine, and damage to the airplane. Actions Since AD 2016–03–03 Was Issued Since we issued AD 2016–03–03, RR determined that additional compressor rotating shrouds and the compressor PO 00000 Frm 00033 Fmt 4702 Sfmt 4702 main shaft, installed on the affected Viper engines, require a reduction in their cyclic life limits. Also since we issued AD 2016–03–03, the European Aviation Safety Agency (EASA) has issued AD 2017–0148, dated August 15, 2017, which requires reducing the cyclic life limits of the affected parts. Related Service Information Under 1 CFR Part 51 RR has issued Alert Service Bulletin (ASBs) Mk. 521 Number 72–A408, Circulation A; Mk. 521 Number 72– A408, Circulation B; Mk. 522 Number 72–A413, Circulation A; Mk. 522 Number 72–A412, Circulation B; and Mk. 601–22 Number 72–A207; all identified as Revision 1 and all dated June 2017. RR ASBs Mk. 521 Number 72–A408, Circulation A (Revision 1) and Mk. 521 Number 72–A408, Circulation B (Revision 1) describe applicable part numbers (P/Ns) and revised cyclic life limits for parts installed on the Mk. 521 engine. RR ASBs Mk. 522 Number 72– A413, Circulation A (Revision 1), and Mk. 522 Number 72–A412, Circulation B (Revision 1) describe applicable P/Ns and revised cyclic life limits for parts installed on the Mk. 522 engine. RR ASB Mk. 601–22 Number 72–A207, Rev. 1, describes applicable P/Ns and revised cyclic life limits for parts installed on the Mk. 601–22 engine. 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 We are proposing this AD because we evaluated all the relevant information and determined the unsafe condition described previously is likely to exist or develop in other products of the same type design. Proposed AD Requirements This proposed AD would require reducing the cyclic life of certain critical parts. This proposed AD would add additional parts to the applicability of AD 2016–03–03. Costs of Compliance We estimate that this proposed AD affects 46 engines installed on helicopters of U.S. registry. We estimate the following costs to comply with this proposed AD: E:\FR\FM\15DEP1.SGM 15DEP1 Federal Register / Vol. 82, No. 240 / Friday, December 15, 2017 / Proposed Rules 59561 ESTIMATED COSTS Action Labor cost Parts cost Cost per product Cost on U.S. operators Remove and replace parts ............................. 4 work-hours × $85 per hour = $340 ............. $75,000 $75,340 $3,465,640 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. This AD is issued in accordance with authority delegated by the Executive Director, Aircraft Certification Service, as authorized by FAA Order 8000.51C. In accordance with that order, issuance of ADs is normally a function of the Compliance and Airworthiness Division, but during this transition period, the Executive Director has delegated the authority to issue ADs applicable to engines, propellers, and associated appliances to the Manager, Engine and Propeller Standards Branch, Policy and Innovation Division. ethrower on DSK3G9T082PROD with PROPOSALS Regulatory Findings We have determined that this proposed AD would not have federalism implications under Executive Order 13132. This proposed AD would 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 the proposed regulation: (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, and VerDate Sep<11>2014 19:43 Dec 14, 2017 Jkt 244001 (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 Air transportation, Aircraft, Aviation safety, Incorporation by reference, Safety. The Proposed Amendment Accordingly, under the authority delegated to me by the Administrator, the FAA proposes to amend 14 CFR part 39 as follows: PART 39—AIRWORTHINESS DIRECTIVES 1.

Airworthiness Directives; Rolls-Royce plc Turbojet Engines

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice of proposed rulemaking (NPRM).

-----------------------------------------------------------------------

SUMMARY: We propose to supersede airworthiness directive (AD) 2016-03-
03 that applies to all Rolls-Royce plc (RR) Viper Mk. 521, Viper Mk. 
522, and Viper Mk. 601-22 turbojet engines. AD 2016-03-03 requires 
reducing the life of certain critical parts. Since we issued AD 2016-
03-03, RR determined that additional parts for these RR Viper engine 
models are affected. This proposed AD would add additional engine parts 
to the applicability. We are proposing this AD to address the unsafe 
condition on these products.

Discussion

    We issued AD 2016-03-03, Amendment 39-18390 (81 FR 12585, March 10, 
2016), ``AD 2016-03-03,'' for all RR Viper Mk. 521, Viper Mk. 522, and 
Viper Mk. 601-22 turbojet engines. AD 2016-03-03 requires reducing the 
life of certain critical parts. AD 2016-03-03 resulted from a 
determination by RR that the life of certain critical engine parts 
needed to be reduced. We issued AD 2016-03-03 to prevent failure of 
life-limited parts, which could lead to an uncontained part release, 
damage to the engine, and damage to the airplane.

Actions Since AD 2016-03-03 Was Issued

    Since we issued AD 2016-03-03, RR determined that additional 
compressor rotating shrouds and the compressor main shaft, installed on 
the affected Viper engines, require a reduction in their cyclic life 
limits. Also since we issued AD 2016-03-03, the European Aviation 
Safety Agency (EASA) has issued AD 2017-0148, dated August 15, 2017, 
which requires reducing the cyclic life limits of the affected parts.

Related Service Information Under 1 CFR Part 51

    RR has issued Alert Service Bulletin (ASBs) Mk. 521 Number 72-A408, 
Circulation A; Mk. 521 Number 72-A408, Circulation B; Mk. 522 Number 
72-A413, Circulation A; Mk. 522 Number 72-A412, Circulation B; and Mk. 
601-22 Number 72-A207; all identified as Revision 1 and all dated June 
2017. RR ASBs Mk. 521 Number 72-A408, Circulation A (Revision 1) and 
Mk. 521 Number 72-A408, Circulation B (Revision 1) describe applicable 
part numbers (P/Ns) and revised cyclic life limits for parts installed 
on the Mk. 521 engine. RR ASBs Mk. 522 Number 72-A413, Circulation A 
(Revision 1), and Mk. 522 Number 72-A412, Circulation B (Revision 1) 
describe applicable P/Ns and revised cyclic life limits for parts 
installed on the Mk. 522 engine. RR ASB Mk. 601-22 Number 72-A207, Rev. 
1, describes applicable P/Ns and revised cyclic life limits for parts 
installed on the Mk. 601-22 engine. 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

    We are proposing this AD because we evaluated all the relevant 
information and determined the unsafe condition described previously is 
likely to exist or develop in other products of the same type design.

Proposed AD Requirements

    This proposed AD would require reducing the cyclic life of certain 
critical parts. This proposed AD would add additional parts to the 
applicability of AD 2016-03-03.

Costs of Compliance

    We estimate that this proposed AD affects 46 engines installed on 
helicopters of U.S. registry.
    We estimate the following costs to comply with this proposed 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 
that is likely to exist or develop on products identified in this 
rulemaking action.
    This AD is issued in accordance with authority delegated by the 
Executive Director, Aircraft Certification Service, as authorized by 
FAA Order 8000.51C. In accordance with that order, issuance of ADs is 
normally a function of the Compliance and Airworthiness Division, but 
during this transition period, the Executive Director has delegated the 
authority to issue ADs applicable to engines, propellers, and 
associated appliances to the Manager, Engine and Propeller Standards 
Branch, Policy and Innovation Division.

Regulatory Findings

    We have determined that this proposed AD would not have federalism 
implications under Executive Order 13132. This proposed AD would 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 the proposed 
regulation:
    (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, 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

    Air transportation, Aircraft, Aviation safety, Incorporation by 
reference, Safety.

The Proposed Amendment

    Accordingly, under the authority delegated to me by the
