Airworthiness Directive · Amendment 39-22395 · Wings
Gulfstream Aerospace LP (Type Certificate Previously Held by Israel Aircraft Industries, Ltd.) Airplanes
This AD applies to Gulfstream Aerospace LP Model Galaxy airplanes and Model Gulfstream 200 airplanes, certificated in any category, serial numbers 004 through 250 inclusive.
The FAA is adopting a new airworthiness directive (AD) for certain Gulfstream Aerospace LP Model Galaxy airplanes and Model Gulfstream 200 airplanes. This AD was prompted by reports that wing flap fairing debonding and corrosion were discovered at certain areas of the lower skin on both wings. This AD requires an inspection for corrosion in certain areas of the wing skin fairings, additional inspections if necessary, resealing the fairings with new fillet seal, and applicable corrective actions, as specified in a Civil Aviation Authority of Israel (CAAI) AD, which is incorporated by reference. The FAA is issuing this AD to address the unsafe condition on these products.
Except as specified in paragraphs (h) and (i) 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-57-2021-12-4, dated January 1, 2022 (CAAI AD ISR I-57-2021-12-4).
(1) Where CAAI AD ISR I-57-2021-12-4 refers to its effective date, this AD requires using the effective date of this AD.
(2) Where the Compliance paragraph of CAAI AD ISR I-57-2021-12-4 requires compliance at a certain time, replace the text “at the next suitable planned maintenance inspection within the next 24 months from the effective date of this AD” with “within 24 months after the effective date of this AD.”
(3) Where the Action paragraph of CAAI AD ISR I-57-2021-12-4 refers to certain service information, replace the text “Gulfstream Service Bulletin No. 200-57-426, dated January 01, 2022, or later approved revision,” with “Gulfstream Service Bulletin No. 200-57-426, Revision 1, dated June 16, 2022, or later approved revision.”
(4) Where the service information specified in CAAI AD ISR I-57-2021-12-4 specifies to report to Gulfstream if “cracks were discovered” and “for any fairing installation location with one or more grid squares with thickness reduction of greater than 10%,” for this AD, cracks and fairing installation locations with one or more grid squares with thickness reduction of greater than 10% must be repaired before further flight using a method approved by the Manager, International Validation Branch, FAA; or CAAI; or CAAI's authorized Designee. If approved by the authorized Designee, the approval must include the Designee's authorized signature.
Although the service information referenced in CAAI AD ISR I-57-2021-12-4 specifies to submit certain information to the manufacturer, this AD does not include that requirement.
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 International Validation Branch, send it to the attention of the person identified in paragraph (k) of this AD. Information may be emailed to: 9-AVS-AIR-730-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.
