Airworthiness Directive · Amendment 39-23461 · Time limits/maintenance checks
Gulfstream Aerospace LP (Type Certificate Previously Held by Israel Aircraft Industries, Ltd.) Airplanes
This AD applies to all Gulfstream Aerospace (Type Certificate previously held by Israel Aircraft Industries, Ltd.) LP Model Gulfstream G150 airplanes, certificated in any category.
The FAA is superseding Airworthiness Directive (AD) 2025-15- 04, which applied to all Gulfstream Aerospace LP Model G150 airplanes. AD 2025-15-04 required revising the existing maintenance or inspection program, as applicable, to incorporate a new airworthiness limitation. Since the FAA issued AD 2025-15-04, the FAA has determined that new or more restrictive airworthiness limitations are necessary. This AD continues to require actions in AD 2025-15-04 and requires revising the existing maintenance or inspection program, as applicable, to incorporate new or more restrictive airworthiness limitations. The FAA is issuing this AD to address the unsafe condition on these products.
This paragraph restates the requirements of paragraph (g) of AD 2025-15-04, with a new terminating action. Except as specified in paragraph (h) of this AD: Comply with all required actions and compliance times specified in, and in accordance with, Civil Aviation Authority of Israel (CAAI) AD ISR I-32-24-10-01R1, revised October 15, 2024 (CAAI AD ISR I-32-24-10-01R1). Accomplishing the revision of the existing maintenance or inspection program required by paragraph (j) of this AD terminates the requirements of this paragraph.
This paragraph restates the exceptions specified in paragraph (h) of AD 2025-15-04, with no changes.
(1) Where CAAI AD ISR I-32-24-10-01R1 refers to its effective date, this AD requires using September 10, 2025 (the effective date of AD 2025-15-04).
(2) The initial compliance time for doing the task specified in the Action paragraph of CAAI AD ISR I-32-24-10-01R1 is at the applicable “discard” interval as specified in the material referenced in the Action paragraph of CAAI AD ISR I-32-24-10-01R1, or within 3 months after September 10, 2025 (the effective date of AD 2025-15-04), whichever occurs later.
(3) Where the Action paragraph of CAAI AD ISR I-32-24-10-01R1 specifies to “incorporate AMM Revision 29”, this AD requires replacing that text with “revise the existing maintenance or inspection program, as applicable, by incorporating the Nose Landing Gear Actuator to Nose Landing Gear Strut Attachment Pin task identified in AMM Revision 29”.
This paragraph restates the requirements of paragraph (i) of AD 2025-15-04, with a new exception. Except as required by paragraph (j) of this AD, after the existing maintenance or inspection program has been revised as required by paragraph (g) of this AD, no alternative actions (e.g., inspections) or intervals are allowed unless they are approved as specified in the provisions of paragraph (m)(1) of this AD.
Except as specified in paragraph (k) of this AD: Comply with all required actions and compliance times specified in, and in accordance with, CAAI AD ISR I-05-2025-10-1, October 15, 2025 (CAAI AD ISR I-05-2025-10-1). Accomplishing the revision of the existing maintenance or inspection program required by this paragraph terminates the requirements of paragraph (g) of this AD.
(1) Where CAAI AD ISR I-05-2025-10-1 refers to its effective date, this AD requires using the effective date of this AD.
(2) Where the Action paragraph of CAAI AD ISR I-05-2025-10-1 specifies to “incorporate AMM Revision 30”, this AD requires replacing the text with “revise the existing maintenance or inspection program, as applicable, to incorporate the information specified in Section 05-10-10 Airworthiness Limitations, Chapter 05 Time Limits/Maintenance Checks, Gulfstream G150 Maintenance Manual, Revision 30, dated September 15, 2025”.
(3) The initial compliance time for doing the tasks specified in the material referenced in the Action paragraph of CAAI AD ISR I-05-2025-10-1 is at the applicable initial inspection interval, comply within time, or discard interval specified in the material referenced in the Action paragraph of CAAI AD ISR I-05-2025-10-1, or within 90 days after the effective date of this AD, whichever occurs later.
After the existing maintenance or inspection program has been revised as required by paragraph (j) of this AD, no alternative actions (e.g., inspections) and intervals are allowed unless they are approved as specified in the provisions of the Action paragraph of CAAI AD ISR I-05-2025-10-1.
The following provisions also apply to this AD.
(1) Alternative Methods of Compliance (AMOCs): The Manager, International Validation Branch, FAA, has the authority to approve AMOCs for this AD, if requested using the procedures found in 14 CFR 39.19.

If sending information directly to the manager of the International Validation Branch, send it to the attention of the person identified in paragraph (n) of this AD and email to: 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 by the Manager, International Validation Branch, FAA; or CAAI; or CAAI's authorized Designee.
