ACTION: Final rule. 

SUMMARY: We are superseding 

Airworthiness Directive (AD) 2016–03– 

03 for all Rolls-Royce plc (RR) Viper 

Mk. 521, Viper Mk. 522, and Viper Mk. 

601–22 turbojet engines. AD 2016–03– 

03 required reducing the life of certain 

critical parts. This AD requires reducing 

the life of certain critical parts and adds 

additional engine parts to the 

applicability. This AD was prompted by 

a determination made by RR that 

additional parts for the applicable RR 

Viper turbojet engine models are 

affected. We are issuing this AD to 

address the unsafe condition on these 

products. 

DATES: This AD is effective September 

25, 2018. 

The Director of the Federal Register 

approved the incorporation by reference 

of certain publications listed in this AD 

as of September 25, 2018.

SUPPLEMENTARY INFORMATION: 

Discussion 

We issued a notice of proposed 

rulemaking (NPRM) to amend 14 CFR 

part 39 to supersede AD 2016–03–03, 

Amendment 39–18390 (81 FR 12585, 

March 10, 2016) (‘‘AD 2016–03–03’’). 

AD 2016–03–03 applied to all RR Viper 

Mk. 521, Viper Mk. 522, and Viper Mk. 

601–22 turbojet engines. The NPRM 

published in the Federal Register on 

December 15, 2017 (82 FR 59560). The 

NPRM was prompted by RR 

determining that additional compressor 

rotating shrouds and the compressor 

main shaft, installed on the affected 

Viper turbojet 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. The NPRM proposed to 

add additional engine parts to the 

applicability. We are issuing this AD to 

address the unsafe condition on these 

products. 

Comments 

We gave the public the opportunity to 

participate in developing this AD. We 

received no comments on the NPRM or 

on the determination of the cost to the 

public. 

Conclusion 

We reviewed the relevant data and 

determined that air safety and the 

public interest require adopting this AD 

as proposed except for minor editorial 

changes.

42208 Federal Register / Vol. 83, No. 162 / Tuesday, August 21, 2018 / Rules and Regulations 

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

limits for parts installed on the Viper 

Mk. 521 turbojet 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 Viper Mk. 522 turbojet engine. The 

content of Circulation A and B of these 

respective ASBs is identical. RR uses 

the designations ‘‘Circulation A’’ and 

‘‘Circulation B’’ to determine 

distribution of service information, 

based on the capabilities of maintenance 

facilities. 

RR ASB Mk. 601–22 Number 72– 

A207, Rev. 1, describes applicable P/Ns 

and revised cyclic life limits for parts 

installed on the Viper Mk. 601–22 

turbojet 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. 

Costs of Compliance 

We estimate that this AD affects 46 

engines installed on airplanes of U.S. 

registry. 

We estimate the following costs to 

comply with this AD: 

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. 

Regulatory Findings 

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.
