V2527E–A5, V2527M–A5, V2530–A5, 

and V2533–A5 model turbofan engines. 

This AD was prompted by a review of 

investigative findings from an event 

involving an uncontained failure of a 

high-pressure turbine (HPT) 1st-stage 

disk that resulted in high-energy debris 

penetrating the engine cowling. This AD 

requires an ultrasonic inspection (USI) 

of affected HPT 1st-stage disks and HPT 

2nd-stage disks and, depending on the 

results of the USI, removal of the 

affected HPT 1st-stage and HPT 2ndstage disks from service. The FAA 

previously sent an emergency AD to all 

known U.S. owners and operators of 

these engines and is now issuing this 

AD to address the unsafe condition on 

these products. 

DATES: This AD is effective July 19, 

2021. Emergency AD 2021–11–51, 

issued on May 21, 2021, which 

contained the requirements of this 

amendment, was effective with actual 

notice.

SUPPLEMENTARY INFORMATION: 

Background 

On May 21, 2021, the FAA issued 

Emergency AD 2021–11–51 (the 

emergency AD), which requires a USI of 

affected HPT 1st-stage disks and HPT 

2nd-stage disks installed on IAE V2522– 

A5, V2524–A5, V2527–A5, V2527E–A5, 

V2527M–A5, V2530–A5, and V2533–A5 

model turbofan engines and, depending 

on the results of the USI, removal of the 

affected HPT disks from service. The 

FAA sent the emergency AD to all 

known U.S. owners and operators of 

these engines. That action was 

prompted by a review of investigative 

findings from an event involving an 

uncontained failure of an HPT 1st-stage 

disk that resulted in high-energy debris 

penetrating the engine cowling. This 

condition, if not addressed, could result 

in uncontained HPT failure, release of 

high-energy debris, damage to the 

engine, damage to the airplane, and loss 

of the airplane. 

FAA’s Determination 

The FAA is issuing this AD because 

the agency 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. 

Related Service Information Under 1 

CFR Part 51 

The FAA reviewed IAE NonModification Service Bulletin (NMSB) 

V2500–ENG–72–0713, Revision 1, dated 

January 26, 2021 (IAE NMSB V2500– 

ENG–72–0713). IAE NMSB V2500– 

ENG–72–0713 specifies procedures for 

performing an ultrasonic inspection of 

the HPT 1st-stage disk and the HPT 2ndstage disk installed on IAE V2500–A5 

and V2500–D5 series engines. 

The FAA also reviewed IAE NMSB 

V2500–E5–72–0015, dated December 

15, 2020 (IAE NMSB V2500–E5–72– 

0015). IAE NMSB V2500–E5–72–0015 

specifies procedures for performing an 

ultrasonic inspection of the HPT 1ststage disk and the HPT 2nd-stage disk 

installed on V2500–E5 series engines. 

The Director of the Federal Register 

approved IAE NMSB V2500–ENG–72– 

0713 and IAE NMSB V2500–E5–72– 

0015 for incorporation by reference as of 

July 13, 2021 (86 FR 30380, June 8, 

2021). 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 

ADDRESSES. 

AD Requirements 

This AD requires a USI of affected 

HPT 1st-stage disks and HPT 2nd-stage 

disks installed on IAE V2522–A5, 


lotter on DSK11XQN23PROD with RULES1

V2524–A5, V2527–A5, V2527E–A5, 

V2527M–A5, V2530–A5, and V2533–A5 

model turbofan engines and, depending 

on the results of the USI, removal of the 

affected HPT disks from service. 

Interim Action 

The FAA considers this AD interim 

action. The root cause of this event is 

still under investigation. 

Justification for Immediate Adoption 

and Determination of the Effective Date 

Section 553(b)(3)(B) of the 

Administrative Procedure Act (APA) (5 

U.S.C. 551 et seq.) authorizes agencies 

to dispense with notice and comment 

procedures for rules when the agency, 

for ‘‘good cause,’’ finds that those 

procedures are ‘‘impracticable, 

unnecessary, or contrary to the public 

interest.’’ Under this section, an agency, 

upon finding good cause, may issue a 

final rule without providing notice and 

seeking comment prior to issuance. 

Further, section 553(d) of the APA 

authorizes agencies to make rules 

effective in less than thirty days, upon 

a finding of good cause. 

An unsafe condition exists that 

required the immediate adoption of 

Emergency AD 2021–11–51, issued on 

May 21, 2021, to all known U.S. owners 

and operators of these engines. The FAA 

has found that the risk to the flying 

public justified forgoing notice and 

comment prior to adoption of this rule. 

On March 18, 2020, an Airbus Model 

A321–231 airplane, powered by IAE 

V2533–A5 model turbofan engines, 

experienced an uncontained HPT 1ststage disk failure that resulted in an 

aborted takeoff. The uncontained failure 

of the HPT 1st-stage disk resulted in 

high-energy debris penetrating the 

engine cowling. The FAA published 

Emergency AD 2020–07–51 on March 

21, 2020 (followed by publication in the 

Federal Register on April 13, 2020, as 

a Final Rule, Request for Comments (85 

FR 20402)), to remove from service HPT 

1st-stage disks identified as having the 

highest risk of failure. Based on a review 

of investigative findings performed 

since that event, the manufacturer has 

identified a different population of 

affected HPT 1st-stage and HPT 2ndstage disks that are affected by the same 

unsafe condition and require USI and, 

depending on the results of the USI, 

removal from service. 

The FAA considers removal of highrisk HPT 1st-stage and 2nd-stage disks 

to be an urgent safety issue. The USI of 

the affected HPT disks must be 

accomplished within 10 flight cycles 

after the effective date of this AD to 

identify HPT 1st-stage and 2nd-stage 

disks at risk of failure and to maintain 

an acceptable level of safety. This 

unsafe condition may result in loss of 

the airplane. These conditions still 

exist, and therefore, notice and 

opportunity for prior public comment 

are impracticable and contrary to public 

interest pursuant to 5 U.S.C. 

553(b)(3)(B). 

In addition, for the reasons stated 

above, the FAA finds that good cause 

exists pursuant to 5 U.S.C. 553(d) for 

making this amendment effective in less 

than 30 days, for the same reasons the 

FAA finds good cause to forego notice 

and comment. 

Comments Invited 

The FAA invites you to send any 

written data, views, or arguments about 

this final rule. Send your comments to 

an address listed under ADDRESSES. 

Include the Docket No. FAA–2021–0509 

and Project Identifier AD–2021–00608– 

E at the beginning of your comments. 

The most helpful comments reference a 

specific portion of the final rule, explain 

the reason for any recommended 

change, and include supporting data. 

The FAA will consider all comments 

received by the closing date and may 

amend this final rule because of those 

comments. 

Except for Confidential Business 

Information (CBI) as described in the 

following paragraph, and other 

information as described in 14 CFR 

11.35, the FAA will post all comments 

received, without change, to https://

www.regulations.gov, including any 

personal information you provide. The 

agency will also post a report 

summarizing each substantive verbal 

contact received about this final rule. 

Confidential Business Information 

CBI is commercial or financial 

information that is both customarily and 

actually treated as private by its owner. 

Under the Freedom of Information Act 

(FOIA) (5 U.S.C. 552), CBI is exempt 

from public disclosure. If your 

comments responsive to this AD contain 

commercial or financial information 

that is customarily treated as private, 

that you actually treat as private, and 

that is relevant or responsive to this AD, 

it is important that you clearly designate 

the submitted comments as CBI. Please 

mark each page of your submission 

containing CBI as ‘‘PROPIN.’’ The FAA 

will treat such marked submissions as 

confidential under the FOIA, and they 

will not be placed in the public docket 

of this AD. Submissions containing CBI 

should be sent to Alberto Hernandez, 

Aviation Safety Engineer, ECO Branch, 

FAA, 1200 District Avenue, Burlington, 

MA 01803. Any commentary that the 

FAA receives which is not specifically 

designated as CBI will be placed in the 

public docket for this rulemaking. 

Regulatory Flexibility Act 

The requirements of the Regulatory 

Flexibility Act (RFA) do not apply when 

an agency finds good cause pursuant to 

5 U.S.C. 553 to adopt a rule without 

prior notice and comment. Because FAA 

has determined that it has good cause to 

adopt this rule without prior notice and 

comment, RFA analysis is not required. 

Costs of Compliance 

The FAA estimates that this AD 

affects 2 engines installed on airplanes 

of U.S. registry. 

The FAA estimates the following 

costs to comply with this AD: 

ESTIMATED COSTS

Action Labor cost Parts cost Cost per 

product 

Cost on U.S. 

operators 

Ultrasonic inspection (includes actions necessary to 

disassemble the engine).

204 work-hours × $85 per hour = 

$17,340.

$0 $17,340 $34,680 

The FAA estimates the following 

costs to do any necessary replacements 

that would be required based on the 

results of the inspection. The agency has 

no way of determining the number of 

aircraft that might need these 

replacements:

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. 

The FAA is 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. 

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, 

and 

(2) Will not affect intrastate aviation 

in Alaska.

Establishment of Class D Airspace and 

Amendment of Class E Airspace; 

Nashville, TN; Correction 

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Final rule; correction. 

SUMMARY: The Federal Aviation 

Administration (FAA) is correcting a 

final rule that appeared in the Federal 

Register on December 1, 2020, 

establishing Class D and E airspace for 

John C. Tune Airport, Nashville, TN. 

This action corrects the legal 

description of the Class D airspace by 

amending the ceiling to 2,500 feet, 

adding the Class E extensions to the 

Class D description, and adjusting the

SUPPLEMENTARY INFORMATION: 

History 

The FAA published a final rule in the 

Federal Register (85 FR 76958; 

December 1, 2020) for Docket FAA– 

2020–0701 establishing Class D airspace 

and Class E airspace designated as an 

extension to a Class D or Class E surface 

area, and amending Class E airspace 

extending upward from 700 feet above 

the surface. Subsequent to publication, 

the FAA identified errors in how the 

Class D airspace is described, as well as 

determining the Class E surface 

extensions needed to be added to the 

Class D description. This action corrects 

these errors. 

Class D and Class E airspace 

designations are published in Paragraph 

5000, 6004 and 6005, respectively, of 

FAA Order 7400.11E, dated July 21, 

2020, and effective September 15, 2020, 

which is incorporated by reference in 14 

CFR 71.1. The Class E airspace 

designations listed in this document 

will be published subsequently in the 

Order.
