Airworthiness Directive · Amendment 39-23207 · Landing gear
Gulfstream Aerospace LP (Type Certificate Previously Held by Israel Aircraft Industries, Ltd.) Airplanes
This AD applies to all Gulfstream Aerospace LP Model Gulfstream 100, Astra SPX, and 1125 Westwind Astra airplanes, certificated in any category.
The FAA is adopting a new airworthiness directive (AD) for all Gulfstream Aerospace LP Model Gulfstream 100, Astra SPX, and 1125 Westwind Astra airplanes. This AD was prompted by a determination that new airworthiness limitations are necessary. This AD requires revising the existing maintenance or inspection program, as applicable, to incorporate new airworthiness limitations. The FAA is issuing this AD to address the unsafe condition on these products.
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-32-25-01-7, dated January 13, 2025 (CAAI AD ISR I-32-25-01-7).
(1) Where CAAI AD ISR I-32-25-01-7 refers to its effective date, this AD requires using the effective date of this AD.
(2) The initial compliance time for doing the tasks specified in the Action paragraph of CAAI AD ISR I-32-25-01-7 is at the applicable discard interval specified in the material referenced in the Action paragraph of CAAI AD ISR I-32-25-01-7, or within 3 months after the effective date of this AD, whichever occurs later.
(3) Where the Action paragraph of CAAI AD ISR I-32-25-01-7 specifies “to incorporate AMM Revision 26”, this AD requires replacing that text with “revise the existing maintenance or inspection program, as applicable, by incorporating the information in the Nose Landing Gear Actuator Attachment Pin—Life Limit (Scrap) tasks for SHL part numbers 2247.0500.007 and 2247.0500.008”.
(4) Where the Action paragraph of CAAI AD ISR I-32-25-01-7 specifies “to incorporate AMM Revision 32”, this AD requires replacing that text with “revise the existing maintenance or inspection program, as applicable, by incorporating the information in the NLG Actuator Attachment Pin—Life Limit (Scrap) tasks for SHL part numbers 2247.0500.007 and 2247.0500.008”.
After the existing maintenance or inspection program has been revised as required by paragraph (g) of this AD, no alternative actions (e.g., inspections) and intervals are allowed unless they are approved as specified in the provisions of paragraph (j)(1) of this AD.
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. 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 manager of the International Validation Branch, send it to the attention of the person identified in paragraph (k) 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. If approved by the CAAI Designee, the approval must include the Designee's authorized signature.
