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 RRC AE 2100D2A and 

AE 2100D3 model turboprop engines 

and AE 3007A2 model turbofan engines. 

The NPRM published in the Federal 

Register on April 30, 2018 (83 FR 

18751). The NPRM was prompted by the 

possibility of a low-cycle fatigue failure 

on certain turbine wheels. The affected 

turbine wheels include 1st-stage gas 

generator turbine wheels, installed on 

AE 2100D2A and AE 2100D3 model 

turboprop engines, and 1st-stage highpressure turbine (HPT) wheels, installed 

on AE 3007A2 turbofan engines. The 

NPRM proposed to require removing the 

affected turbine wheels at the next 

engine shop visit or before reaching the 

new reduced life limit, whichever 

occurs first, and replacing them with 

parts eligible for installation. 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 final rule. 

We have considered the comment 

received. RRC supported the NPRM. 

Conclusion 

We reviewed the relevant data, 

considered the comments received, and 

determined that air safety and the 

public interest require adopting this 

final rule as proposed. 

Related Service Information Under 1 

CFR Part 51 

We reviewed RRC Alert Service 

Bulletin (ASB) AE 2100D2–A–72–090, 

Revision 1, dated July 11, 2014, and 

RRC ASB AE 2100D3–A–72–286, 

Revision 1, dated July 11, 2014 (one 

document, referred to herein as ‘‘RRC 

ASB AE 2100D2–A–72–090/AE 

2100D3–A–72–286’’), and RRC ASB AE 

3007A–A–72–419, Revision 2, dated 

December 4, 2017. RRC ASB AE 

2100D2–A–72–090/AE 2100D3–A–72– 

286 provides removal and replacement 

instructions and a new life limit for the 

affected 1st-stage gas generator turbine 

wheels installed on RRC AE 2100D2A 

and AE 2100D3 model turboprop 

engines. ASB AE 3007A–A–72–419 

provides removal and replacement 

instructions and a new life limit for 1ststage HPT wheels installed on RRC AE 

3007A2 model turbofan engines. 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 nine 

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 

Replace turbine wheels ........................ 0 work-hours × $85 per hour = $0 ............................ $160,829 $160,829 $1,447,461 

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 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 


daltland on DSKBBV9HB2PROD with RULES
Federal Register / Vol. 83, No. 160 / Friday, August 17, 2018 / Rules and Regulations 40963 

(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.

of steel inclusions in the turbine wheel 

forging. We are proposing this AD to prevent 

a low-cycle fatigue failure of a 1st-stage gas 

generator turbine wheel or 1st-stage HPT 

wheel. The unsafe condition, if not 

addressed, could result in uncontained 

turbine wheel release, damage to the engine, 

and damage to the airplane. 

(f) Compliance 

Comply with this AD within the 

compliance times specified, unless already 

done. 

(g) Required Actions 

(1) Remove the affected 1st-stage gas 

generator turbine wheel and replace with a 

part eligible for installation at the next engine 

shop visit or before exceeding the life limit 

of 4,800 engine cycles, whichever occurs 

first, in accordance with the 

Accomplishment Instructions, Paragraph 2, 

of RRC Alert Service Bulletin (ASB) AE 

2100D2–A–72–090, Revision 1, dated July 11, 

2014, and RRC ASB AE 2100D3–A–72–286, 

Revision 1, dated July 11, 2014 (co-published 

as one document). 

(2) Remove the affected 1st-stage HPT 

wheel and replace with a part eligible for 

installation at the next engine shop visit or 

before exceeding the life limit of 5,600 engine 

cycles, whichever occurs first, in accordance 

with the Accomplishment Instructions, 

Paragraph 2, of RRC ASB AE 3007A–A–72– 

419, Revision 2, dated December 4, 2017. 

(h) Definition 

For the purpose of this AD, an ‘‘engine 

shop visit’’ is the induction of an engine into 

the shop for maintenance involving the 

separation of pairs of major mating engine 

flanges, except that the separation of engine 

flanges solely for the purposes of 

transportation without subsequent engine 

maintenance is not an engine shop visit. 

(i) Alternative Methods of Compliance 

(AMOCs) 

(1) The Manager, Chicago ACO Branch, 

FAA, has the authority to approve AMOCs 

for this AD, if requested using the procedures 

found in 14 CFR 39.19. In accordance with
