SUPPLEMENTARY INFORMATION: 

Discussion 

We issued a notice of proposed 

rulemaking (NPRM) to amend 14 CFR 

part 39 by adding an AD that would 

apply to certain RRD Tay 620–15 

turbofan engines. The NPRM published 

in the Federal Register on April 30, 

2018 (83 FR 18758). The NPRM was 

prompted by reports of LPC fan blade 

retention lug failures. The NPRM 

proposed to require reviewing the 

engine maintenance records and 

replacing the LPC fan blade with a part 

eligible for installation if the DFL 

treatment limit is exceeded. We are 

issuing this AD to address the unsafe 

condition on these products. 

The European Aviation Safety Agency 

(EASA), which is the Technical Agent 

for the Member States of the European 

Community, has issued EASA AD 2018– 

0013, dated January 17, 2018 (referred to 

after this as ‘‘the MCAI’’), to address the 

unsafe condition on these products. The 

MCAI states: 

Fractures of low pressure compressor (LPC) 

fan blade retention lugs were reported on 

engines subjected to a high number of Dry 

Film Lubrication (DFL) treatments. 

Subsequent investigation determined that, as 

a consequence, the retention lugs of the 

affected LPC (fan) blades had been exposed 

to excessive high stress cycles. 

This condition, if not detected or corrected, 

could lead to failure of LPC fan blade 

retention lug(s), high vibration, reduced 

thrust, or in-flight shut down, possibly 

resulting in reduced control of the aeroplane. 

To address this potential unsafe condition, 

Rolls Royce Deutschland (RRD) issued Alert 

Non-Modification Service Bulletin (NMSB) 

TAY–72–A1834 (hereafter referred to as ‘the 

NMSB’) to provide identification and 

replacement instructions. 

For the reasons described above, this 

[EASA] AD requires determination of number 

of DFL treatments applied to the LPC fan 

blades and, based on that determination, 

replacement. This [EASA] AD also 

introduces a maximum allowable number of 

DFL treatments applicable to the LPC fan 

blades. 

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–2018– 

0235. 

Comments 

We gave the public the opportunity to 

participate in developing this final rule. 

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 

final rule as proposed except for minor 

editorial changes. 

• Are consistent with the intent that 

was proposed in the NPRM for 

addressing the unsafe condition; and 

• Do not add any additional burden 

upon the public than was already 

proposed in the NPRM.

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 

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, 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.
