Airworthiness Directives; Gulfstream 

Aerospace LP Airplanes; Correction 

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Final rule; correction. 

SUMMARY: The FAA is correcting an 

airworthiness directive (AD) that was 

published in the Federal Register. That 

AD applies to certain Gulfstream 

Aerospace LP Model Gulfstream G280 

airplanes. As published, the document 

number of the Civil Aviation Authority 

of Israel (CAAI) AD specified in the 

preamble and regulatory text is 

incorrect. This document corrects that 

error. In all other respects, the original 

document remains the same. 

DATES: This correction is effective 

October 14, 2021. The effective date of 

AD 2021–17–14 remains October 14, 

2021. 

The Director of the Federal Register 

approved the incorporation by reference 

of a certain publication listed in this AD 

as of October 14, 2021 (86 FR 50451, 

September 9, 2021).

SUPPLEMENTARY INFORMATION: AD 2021– 

17–14, Amendment 39–21697 (86 FR 

50451, September 9, 2021) (AD 2021– 

17–14), requires non-destructive testing 

on the forward (front) spar vertical 

stiffener and rib 0 for any cracking, 

installation of a doubler to the forward 

(front) spar and rib 0 attachment, and 

repair if necessary. That AD applies to 

certain Gulfstream Aerospace LP Model 

Gulfstream G280 airplanes. 

Need for the Correction 

As published, the document number 

of the CAAI AD specified in the 

preamble and regulatory text of AD 

2021–17–14 is incorrect. The document 

number of the CAAI AD is incorrectly 

cited as ‘‘CAAI AD I–57–2020–06–01.’’ 

The correct document number should 

read as, ‘‘CAAI AD ISR–I–57–2020–06– 

01.’’ 

Related Service Information Under 1 

CFR Part 51 

CAAI AD ISR–I–57–2020–06–01, 

dated January 27, 2021, specifies 

procedures for non-destructive testing 

(high frequency, mid frequency, and 

bolt hole eddy current inspections; and 

a liquid (dye) penetrant inspection) for 

cracking on the forward (front) spar 

vertical stiffener and rib 0, installation 

of a doubler to the forward (front) spar 

and rib 0 attachment, and repair if 

necessary. 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. 

Correction of Publication 

This document corrects an error and 

correctly adds the AD as an amendment 

to 14 CFR 39.13. Although no other part 

of the preamble or regulatory 

information has been corrected, the 

FAA is publishing the entire rule in the 

Federal Register. 

The effective date of this AD remains 

October 14, 2021. 

Since this action only corrects the 

document number of the CAAI AD, it 

has no adverse economic impact and 

imposes no additional burden on any 

person. Therefore, the FAA has 

52600 Federal Register / Vol. 86, No. 181 / Wednesday, September 22, 2021 / Rules and Regulations 

determined that notice and public 

procedures are unnecessary. 

List of Subjects in 14 CFR Part 39 

Air transportation, Aircraft, Aviation 

safety, Incorporation by reference, 

Safety. 

Adoption of the Correction 

Accordingly, pursuant to the 

authority delegated to me by the 

Administrator, the Federal Aviation 

Administration amends part 39 of the 

Federal Aviation Regulations (14 CFR 

part 39) as follows: 

PART 39—AIRWORTHINESS 

DIRECTIVES 

■ 1. The authority citation for part 39 

continues to read as follows: 

Authority: 49 U.S.C. 106(g), 40113, 44701. 

§ 39.13 [Corrected] 

■ 2. The FAA corrects § 39.13 by 

correcting the airworthiness directive 

published at (86 FR 50451) (October 14, 

2021) to read: 

2021–17–14 Gulfstream Aerospace LP: 

Amendment 39–21697; Docket No. 

FAA–2021–0459; Project Identifier 

MCAI–2021–00129–T. 

(a) Effective Date 

This airworthiness directive (AD) is 

effective October 14, 2021. 

(b) Affected ADs 

None. 

(c) Applicability 

This AD applies to Gulfstream Aerospace 

LP Model Gulfstream G280 airplanes, 

certificated in any category, as identified in 

The Civil Aviation Authority of Israel (CAAI) 

AD ISR–I–57–2020–06–01, dated January 27, 

2021 (CAAI AD ISR–I–57–2020–06–01). 

(d) Subject 

Air Transport Association (ATA) of 

America Code 57, Wings. 

(e) Reason 

This AD was prompted by a report that 

during full-scale fatigue testing, a crack was 

found in the area of the attachment of the 

wing rib 0 to the front spar. The FAA is 

issuing this AD to address any cracking at the 

area of the wing rib 0 to the front spar, which 

could affect the structural integrity of the 

wing. 

(f) Compliance 

Comply with this AD within the 

compliance times specified, unless already 

done. 

(g) Requirements 

Except as specified in paragraph (h) of this 

AD: Comply with all required actions and 

compliance times specified in, and in 

accordance with, CAAI AD ISR–I–57–2020– 

06–01. 

(h) Exception to CAAI AD ISR–I–57–2020– 

06–01 

Where CAAI AD ISR–I–57–2020–06–01 

requires compliance ‘‘not later than 5,000 

flight cycles,’’ this AD requires compliance 

before the accumulation of 5,000 total flight 

cycles since the date of issuance of the 

original Israeli airworthiness certificate or the 

date of issuance of the original Israeli export 

certificate of airworthiness. 

(i) No Reporting Requirement 

Although the service information 

referenced in CAAI AD ISR–I–57–2020–06– 

01 specifies to submit certain information to 

the manufacturer, this AD does not include 

that requirement. 

(j) Additional AD Provisions 

The following provisions also apply to this 

AD: 

(1) Alternative Methods of Compliance 

(AMOCs): The Manager, Large Aircraft 

Section, International Validation Branch, 

FAA, has the authority to approve AMOCs

14 CFR 39.19, send your request to your 

principal inspector or responsible Flight 

Standards Office, as appropriate. If sending 

information directly to the Large Aircraft 

Section, International Validation Branch, 

send it to the attention of the person 

identified in paragraph (k) of this AD. 

Information may be emailed to: 9-AVS-AIR730-AMOC@faa.gov. Before using any 

approved AMOC, notify your appropriate 

principal inspector, or lacking a principal 

inspector, the manager of the responsible 

Flight Standards Office. 

(2) Contacting the Manufacturer: For any 

requirement in this AD to obtain instructions 

from a manufacturer, the instructions must 

be accomplished using a method approved

Airworthiness Directives; Pratt & 

Whitney Turbofan Engines 

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Final rule. 

SUMMARY: The FAA is adopting a new 

airworthiness directive (AD) for all Pratt 

& Whitney PW1500G and PW1900G 

series turbofan engines with a certain 

high-pressure turbine (HPT) 1st-stage 

hub or HPT rotor 1st-stage blade 

retaining plate installed. This AD was 

prompted by a report from the 

manufacturer who determined that the 

HPT 1st-stage hub and HPT rotor 1ststage blade retaining plate fail to meet 

the published life-cycle limits for each 

part. This AD requires removal and 

replacement of the HPT 1st-stage hub 

and HPT rotor 1st-stage blade retaining 

plate prior to reaching certain cycle 

limits. The FAA is issuing this AD to 

address the unsafe condition on these 

products. 

DATES: This AD is effective October 27, 

2021.
