1. The authority citation for part 39 continues to read as follows: Authority: 49 U.S.C. 106(g), 40113, 44701. 2. The FAA amends § 39.13 by adding the following new airworthiness directive: 2025-15-04 Gulfstream Aerospace LP (Type Certificate Previously Held by Israel Aircraft Industries, Ltd.): Amendment 39-23091; Docket No. FAA-2025-0756; Project Identifier MCAI-2024-00595-T. (a) Effective Date This airworthiness directive (AD) is effective September 10, 2025. (b) Affected ADs None. (c) Applicability This AD applies to all Gulfstream Aerospace LP (Type Certificate previously held by Israel Aircraft Industries, Ltd.) Model Gulfstream G150 airplanes, certificated in any category. (d) Subject Air Transport Association (ATA) of America Code 05, Time Limits/Maintenance Checks; 32, Landing Gear. (e) Unsafe Condition This AD was prompted by a determination that a new airworthiness limitation is necessary. The FAA is issuing this AD to prevent failure of the nose landing gear (NLG) actuator-to-strut attachment pin. The unsafe condition, if not addressed, could result in failure of the NLG to retract and lock after take-off or extend and lock before landing. (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, 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). (h) Exceptions to CAAI AD ISR I-32-24-10-01R1 (1) Where CAAI AD ISR I-32-24-10-01R1 refers to its effective date, this AD requires using the effective date of this AD. (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 the effective date of this AD, 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". (i) Provisions for Alternative Actions and Intervals 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 (j)(1) of this AD.
