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. The AD applies to certain Gulfstream 
Aerospace Corporation Models G-IV and GIV-X airplanes. Paragraphs 
(h)(3) through (5) of the AD incorrectly reference Customer Bulletin 
238A as Customer Bulletin 283A. This document corrects that error. In 
all other respects, the original document remains the

same; however for the sake of clarity, we are publishing the entire 
rule in the Federal Register.

DATES: The effective date of AD 2018-09-04 remains June 11, 2018.
    The Director of the Federal Register approved the incorporation by 
reference of certain publications listed in this AD as of June 11, 2018 
(83 FR 19922, May 7, 2018).

SUPPLEMENTARY INFORMATION: AD 2018-09-04, Amendment 39-19260 (83 FR 
19922, May 7, 2018), requires incorporating new revisions into the 
Instructions for Continued Airworthiness of the Limitations section of 
the FAA-approved maintenance program (e.g., maintenance manual) that 
establish an inspection cycle for the repaired main landing gear side 
brace actuator fittings.
    As published, paragraphs (h)(3) through (5) of the AD contain a 
typographical error. The published references are Customer Bulletin No. 
283A, dated June 15, 2017, and they should be Customer Bulletin No. 
238A, dated June 15, 2017.
    Although no other part of the preamble or regulatory information 
has been corrected, for the sake of clarity, we are publishing the 
entire rule in the Federal Register.
    The effective date of this AD remains June 11, 2018.

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 amends 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 amends Sec.  39.13 by adding the following new airworthiness 
directive (AD):

2018-09-04 Gulfstream Aerospace Corporation: Amendment 39-19260; 
Docket No. FAA-2017-1163; Product Identifier 2017-CE-041-AD.

(a) Effective Date

    This AD is effective June 11, 2018.

(b) Affected ADs

    None.

(c) Applicability

    This AD applies to the following Gulfstream Aerospace 
Corporation model airplanes that are certificated in any category:
    (1) Model G-IV, serial numbers (S/Ns) 1000 through 1399 having 
Aircraft Service Change (ASC) 416A (MSG-3) incorporated; and S/Ns 
1400 through 1535; and
    (2) Model GIV-X, S/Ns 4001 through 4355.

(d) Subject

    Joint Aircraft System Component (JASC)/Air Transport Association 
(ATA) of America Code 32, Landing Gear.

(e) Unsafe Condition

    This AD was prompted by the potential for fatigue cracks in the 
main landing gear (MLG) actuator attachment fitting that had a 
certain repair incorporated. We are issuing this AD to prevent 
failure of the MLG actuator attachment. The unsafe condition, if not 
addressed, could compromise the lateral support of the MLG during 
ground maneuvers, possibly leading to collapse of the affected MLG 
with consequent loss of control. In addition, this condition could 
also cause the MLG side brace to fail, which could result in a 
penetration of the wing fuel tank causing an uncontained fire.

(f) Compliance

    At whichever of the following compliance times in paragraphs 
(f)(1) and (f)(2) that occurs later, comply with the actions in 
paragraphs (g) through (i) of this AD, unless already done.
    (1) Within the next 100 hours time-in-service after June 11, 
2018 (the effective date of this AD); or
    (2) Within the next 3 months after June 11, 2018 (the effective 
date of this AD).

(g) Inspect Maintenance Records

    Inspect the airplane maintenance records to determine if repair 
SE05732102 for the MLG side brace fitting has been incorporated. To 
do this inspection, use the Accomplishment Instructions in 
Gulfstream G350 Customer Bulletin Number 192A; Gulfstream G450 
Customer Bulletin 192A; Gulfstream IV Customer Bulletin Number 238A; 
Gulfstream G300 Customer Bulletin Number 238A; and Gulfstream G400 
Customer Bulletin Number 238A; all dated June 15, 2017, as 
applicable. The service information referenced in this paragraph 
specifies sending a service reply card back to Gulfstream Aerospace 
Corporation if repair SE05732102 for the MLG side brace fitting has 
been not been incorporated. This action is not required in this AD.

(h) Determine Initial and Repetitive Inspection Requirements

    If it is determined during the maintenance records inspection 
required in paragraph (g) that repair SE05732102 for the MLG side 
brace fitting has been incorporated, determine the initial and 
repetitive inspection requirements using the Accomplishment 
Instructions of the service information identified in paragrap (g) 
along with the following documents, as applicable. Comply with the 
inspection requirements as determined.
    (1) Appendix A, Gulfstream Document GIV-SGER-553, Revision A, 
Instructions for Continued Airworthiness for Gulfstream Repair 
Drawing SE05732102, dated December 14, 2016, to Gulfstream G350 
Customer Bulletin No. 192A, dated June 15, 2017;
    (2) Appendix A, Gulfstream Document GIV-SGER-553, Revision A, 
Instructions for Continued Airworthiness for Gulfstream Repair 
Drawing SE05732102, dated December 14, 2016, to Gulfstream G450 
Customer Bulletin No. 192A, dated June 15, 2017;
    (3) Appendix A, Gulfstream Document GIV-SGER-553, Revision A, 
Instructions for Continued Airworthiness for Gulfstream Repair 
Drawing SE05732102, dated December 14, 2016, to Gulfstream IV 
Customer Bulletin No. 238A, dated June 15, 2017;
    (4) Appendix A, Gulfstream Document GIV-SGER-553, Revision A, 
Instructions for Continued Airworthiness for Gulfstream Repair 
Drawing SE05732102, dated December 14, 2016, to Gulfstream G300 
Customer Bulletin No. 238A, dated June 15, 2017; and
    (5) Appendix A, Gulfstream Document GIV-SGER-553, Revision A, 
Instructions for Continued Airworthiness for Gulfstream Repair 
Drawing SE05732102, dated December 14, 2016, to Gulfstream G400 
Customer Bulletin No. 238A, dated June 15, 2017.

(i) Revise Limitations Section

    Insert the documents listed in paragraphs (h)(1) through (5) of 
this AD into the Instructions for Continued Airworthiness of the 
Limitations section of the FAA-approved maintenance program (e.g., 
maintenance manual), as applicable. The revised limitations sections 
establish inspections of the repaired MLG side brace actuator 
fittings.

(j) 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

[[Page 26838]]

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 (k) 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) For service information that contains steps that are labeled 
as Required for Compliance (RC), the provisions of paragraphs (g) 
through (i) of this AD apply.
    (i) The steps labeled as RC, including substeps under an RC step 
and any figures identified in an RC step, must be done to comply 
with the AD. An AMOC is required for any deviations to RC steps, 
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.
