SUPPLEMENTARY INFORMATION: 

Discussion 

We received information concerning 

damage to the engine fan hub found 

during an engine shop visit of an IAE 

PW1100G-series turbofan engine. The 

damage is believed to be the result of 

the installation of the inlet cone without 

using alignment pins, which might lead 

to bolts impacting and damaging the 

engine fan hub. This condition, if not 

addressed, could result in uncontained 

failure of the engine fan hub, damage to 

the engine, and damage to the airplane. 

We are issuing this AD to address the 

unsafe condition on these products. 

Related Service Information Under 1 

CFR Part 51 

We reviewed Pratt & Whitney (PW) 

Service Bulletin (SB) PW1000G–C–72– 

00–0104–00A–930A–D, Issue No. 002, 

dated May 31, 2018. The SB describes 

procedures for performing a one-time 

visual inspection of the inlet cone 

mating face and counter weight flange 

on the engine fan hub assembly for 

surface damage. 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 issuing 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. 

AD Requirements 

This AD requires a one-time visual 

inspection of the engine fan hub for 

damage, and replacement of the engine 

fan hub if damage or defects are found 

that are outside of serviceable limits. 

Differences Between the AD and the 

Service Information 

PW SB PW1000G–C–72–00–0104– 

00A–930A–D, Issue No. 002, dated May 

31, 2018, only applies to PW1100G–JM 

engine models in service. This AD 

applies to all PW1100G–JM engine 

models certified under type certificate 

E00087EN. PW SB PW1000G–C–72–00– 

0104–00A–930A–D also excludes from 

its applicability certain serial numbered 

engines. We have no way to determine 

if these engines have been inspected 

and are therefore including these 

engines in the applicability of this AD. 

Interim Action 

We consider this AD interim action. 

An investigation to determine the cause 

of the failure is on-going and we may 

consider additional rulemaking if final 

action is identified.

29666 Federal Register / Vol. 83, No. 123 / Tuesday, June 26, 2018 / Rules and Regulations 

FAA’s Justification and Determination 

of the Effective Date 

An unsafe condition exists that 

requires the immediate adoption of this 

AD without providing an opportunity 

for public comments prior to adoption. 

The FAA has found that the risk to the 

flying public justifies waiving notice 

and comment prior to adoption of this 

rule because the compliance time is less 

than the time required for public 

comment. In addition, all engine fan 

hubs must be inspected, and if needed, 

replaced before further flight. Therefore, 

we find good cause that notice and 

compliance for prior public comment 

are impracticable. In addition, for the 

reasons stated above, we find that good 

cause exists for making this amendment 

effective in less than 30 days. 

Comments Invited 

This AD is a final rule that involves 

requirements affecting flight safety and 

was not preceded by notice and an 

opportunity for public comment. 

However, we invite you to send any 

written data, views, or arguments about 

this final rule. Send your comments to 

an address listed under the ADDRESSES

section. Include the docket number 

FAA–2018–0564 and Product Identifier 

2018–NE–23–AD at the beginning of 

your comments. We specifically invite 

comments on the overall regulatory, 

economic, environmental, and energy 

aspects of this final rule. We will 

consider all comments received by the 

closing date and may amend this final 

rule because of those comments. 

We will post all comments we 

receive, without change, to http://

www.regulations.gov, including any 

personal information you provide. We 

will also post a report summarizing each 

substantive verbal contact we receive 

about this final rule. 

Costs of Compliance 

We estimate that this AD affects 14 

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 

Visual inspection ............................................. 2 work-hours × $85 per hour = $170 ............. $0 $170 $2,380 

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 

(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.

IFR Altitudes; Miscellaneous 

Amendments 

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Final rule. 

SUMMARY: This amendment adopts 

miscellaneous amendments to the 

required IFR (instrument flight rules) 

altitudes and changeover points for 

certain Federal airways, jet routes, or 

direct routes for which a minimum or 

maximum en route authorized IFR 

altitude is prescribed. This regulatory 

action is needed because of changes 

occurring in the National Airspace 

System. These changes are designed to 

provide for the safe and efficient use of 

the navigable airspace under instrument 

conditions in the affected areas. 

DATES: Effective Date: 0901 UTC, July 

19, 2018.

telephone: (405) 954–4164. 

SUPPLEMENTARY INFORMATION: This 

amendment to part 95 of the Federal 

Aviation Regulations (14 CFR part 95) 

amends, suspends, or revokes IFR 

altitudes governing the operation of all 

aircraft in flight over a specified route 

or any portion of that route, as well as 

the changeover points (COPs) for 

Federal airways, jet routes, or direct 

routes as prescribed in part 95. 

The Rule 

The specified IFR altitudes, when 

used in conjunction with the prescribed 

changeover points for those routes, 

ensure navigation aid coverage that is 

adequate for safe flight operations and 

free of frequency interference. The 

reasons and circumstances that create 

the need for this amendment involve 

matters of flight safety and operational 

efficiency in the National Airspace 

System, are related to published 

aeronautical charts that are essential to 

the user, and provide for the safe and 

efficient use of the navigable airspace. 

In addition, those various reasons or 

circumstances require making this 

amendment effective before the next 

scheduled charting and publication date 

of the flight information to assure its 

timely availability to the user. The 

effective date of this amendment reflects 

those considerations. In view of the 

close and immediate relationship 

between these regulatory changes and 

safety in air commerce, I find that notice 

and public procedure before adopting 

this amendment are impracticable and 

contrary to the public interest and that 

good cause exists for making the 

amendment effective in less than 30 

days. 

Conclusion 

The FAA has determined that this 

regulation only involves an established 

body of technical regulations for which 

frequent and routine amendments are 

necessary to keep them operationally 

current. It, therefore—(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); and (3) 

does not warrant preparation of a 

regulatory evaluation as the anticipated 

impact is so minimal. For the same 

reason, the FAA certifies that this 

amendment will not have a significant 

economic impact on a substantial 

number of small entities under the 

criteria of the Regulatory Flexibility Act.
