14 CFR Part 39

[Docket No. FAA-2021-0459; Project Identifier MCAI-2021-00129-T; 
Amendment 39-21697; AD 2021-17-14]

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).

ADDRESSES: For service information identified in this final rule,

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

[[Page 52600]]

determined that notice and public procedures are unnecessary.

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

0
1. The authority citation for part 39 continues to read as follows:

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


Sec.  39.13  [Corrected]

0
2. The FAA corrects Sec.  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 for this AD, if requested using the 
procedures found in 14 CFR 39.19. In accordance with 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: [email protected]. 
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 by the Manager, Large Aircraft 
Section, International Validation Branch, FAA; or CAAI; or CAAI's 
authorized Designee. If approved by the CAAI Designee, the approval 
must include the Designee's authorized signature.
