14 CFR Part 39

[Docket No. FAA-2021-0958; Project Identifier 2019-CE-010-AD; Amendment 
39-22133; AD 2022-16-04]

Airworthiness Directives; Gulfstream Aerospace Corporation 
Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Final rule; correction.

-----------------------------------------------------------------------

SUMMARY: The FAA is correcting an airworthiness directive (AD) that 
published in the Federal Register. That AD applies to all Gulfstream 
Aerospace Corporation (Gulfstream) Model GV and GV-SP airplanes. As 
published, a revision level and a table number in certain document 
citations in the Credit for Previous Actions section of the regulatory 
text are incorrect. This document corrects those errors. In all other 
respects, the original document remains the same.

DATES: This correction is effective September 7, 2022. The effective 
date of AD 2022-16-04 remains September 7, 2022.
    The Director of the Federal Register approved the incorporation by 
reference of certain publications listed in this AD as of September 7, 
2022 (87 FR 47337, August 3, 2022).

SUPPLEMENTARY INFORMATION: AD 2022-16-04, Amendment 39-22133 (87 FR 
47337, August 3, 2022) (AD 2022-16-04), requires inspecting the 
horizontal stabilizer lower skin and associated bonded doublers and 
bonded stringers, repairing any area with corrosion beyond allowable 
damage limits, and incorporating revisions to the airworthiness 
limitations section (ALS) in the existing aircraft maintenance manual 
(AMM) or progressive maintenance program for all Gulfstream Model GV 
and GV-SP airplanes.

Need for the Correction

    As published, the regulatory text of AD 2022-16-04 includes the 
following errors:
     The revision level of the Gulfstream V Aircraft 
Maintenance Manual specified in paragraph (j)(1) of the regulatory text 
is incorrectly identified as ``Revision 53.'' The correct revision for 
February 28, 2020, is ``Revision 51''; and
     The number specified for the Horizontal Stabilizer 
Inspection Table in the document citation in paragraph (j)(2) of the 
regulatory text is incorrectly referenced as ``Table 11.'' The correct 
reference is ``Table 12.''

Related Service Information Under 1 CFR Part 51

    The FAA reviewed Gulfstream G500-5000 Customer Bulletin No. 190, 
Revision B; Gulfstream G550 Customer Bulletin No. 190, Revision B; and 
Gulfstream GV Customer Bulletin No. 228, Revision B; all dated October 
31, 2019. For the applicable marketing designation specified on each 
document, the customer bulletins specify procedures for inspecting the 
horizontal stabilizer lower bonded skin.
    The FAA also reviewed Section F and Table 12: Horizontal Stabilizer 
Inspection Table in Section 05-10-10, Airworthiness Limitations, of 
Chapter 05, Time Limits/Maintenance Checks, of the Gulfstream V 
Aircraft Maintenance Manual, Revision 55, dated March 15, 2022; Section 
F and Table 11: Horizontal Stabilizer Inspection Table in Section 05-
10-10, Airworthiness Limitations, of Chapter 05, Time Limits/

[[Page 52664]]

Maintenance Checks, of the Gulfstream G500-5000 Aircraft Maintenance 
Manual, Revision 36, dated March 15, 2022; and Section F and Table 11: 
Horizontal Stabilizer Inspection Table in Section 05-10-10, 
Airworthiness Limitations, of Chapter 05, Time Limits/Maintenance 
Checks, of the Gulfstream G550 Aircraft Maintenance Manual, Revision 
36, dated March 15, 2022. For the applicable marketing designation 
specified on each document, the service information contains inspection 
intervals for nondestructive testing of the lower horizontal stabilizer 
skins and provides the specific reference for the inspection 
procedures.
    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 two typographical errors 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 
republishing the entire rule in the Federal Register.
    The effective date of this AD remains September 7, 2022.
    Since this action only corrects a revision level and table number 
in document citations in the regulatory text, it has no adverse 
economic impact and imposes no additional burden on any person. 
Therefore, the FAA has 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, under the authority delegated to me by the 
Administrator, the FAA corrects 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]

2. The FAA corrects Sec.  39.13 by correcting the airworthiness 
directive published at 87 FR 47337 (August 3, 2022) to read:

2022-16-04 Gulfstream Aerospace Corporation: Amendment 39-22133;

    (1) Within 48 months after applying CIC, repair all bond line 
corrosion.
    (2) If there is bond line corrosion that exceeds the allowable 
damage limits in Table 2 of appendix A of the applicable customer 
bulletin listed in paragraph (h) of this AD, or other allowable 
damage limits established by an appropriately authorized Gulfstream 
Organization Designation Authorization (ODA) unit member, repair all 
bond line corrosion before further flight using a repair approved by 
the FAA or an appropriately authorized Gulfstream ODA unit member.
    (i) For a repair method to be approved by the FAA, the FAA's 
approval of the repair must specifically refer to this AD.
    (ii) For a repair method to be approved by a Gulfstream ODA unit 
member, the unit member must be authorized in writing by the Manager

(k) Alternative Methods of Compliance (AMOCs)

    (1) The Manager, Atlanta 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 14 CFR 39.19, send your request 
to your principal inspector or local Flight Standards District 
Office, as appropriate. If sending information directly to the 
manager of the certification office, send it to the attention of the 
person identified in paragraph (l)(1) of this AD.
    (2) Before using any approved AMOC, notify your appropriate 
principal inspector, or lacking a principal inspector, the manager 
of the local flight standards district office/certificate holding 
district office.
    (3) An AMOC that provides an acceptable level of safety may be 
used for any repair, modification, or alteration required by this AD 
if it is approved by a Gulfstream Engineering Authorized 
Representative (EAR) of the Gulfstream ODA that has been authorized 
by the Manager, Atlanta ACO Branch, to make those findings. To be 
approved, the repair, modification deviation, or alteration 
deviation must meet the certification basis of the airplane, and the 
approval must specifically refer to this AD.
    (4) For service information that contains steps that are labeled 
as Required for Compliance (RC), the following provisions apply.
    (i) The steps labeled as RC, including substeps under an RC step 
and any figures identified in an RC step, that are required by 
paragraph (i) of this AD must be done to comply with this AD. An 
AMOC is required for any deviations to RC steps required by 
paragraph (i) of this AD, including substeps and identified figures.
    (ii) Steps not labeled as RC may be deviated from using accepted 
methods in accordance with the operator's maintenance or inspection 
program without obtaining approval of an AMOC, provided the RC 
steps, including substeps and identified figures, can still be done 
as specified, and the airplane can be put back in an airworthy 
condition.
