AD 2021-17-14

This airworthiness directive (AD) is effective October 14, 2021.

None.

This AD applies to Gulfstream Aerospace LP Model Gulfstream G280 airplanes, certificated in any category, as identified in The Civil Aviation Authority of Israel (CAAI) AD ISR-I-57-2020-06-01, dated January 27, 2021 (CAAI AD ISR-I-57-2020-06-01).

Air Transport Association (ATA) of America Code 57, Wings.

This AD was prompted by a report that during full-scale fatigue testing, a crack was found in the area of the attachment of the wing rib 0 to the front spar. The FAA is issuing this AD to address any cracking at the area of the wing rib 0 to the front spar, which could affect the structural integrity of the wing.

Comply with this AD within the compliance times specified, unless already done.

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-57-2020-06-01.

Where CAAI AD ISR-I-57-2020-06-01 requires compliance “not later than 5,000 flight cycles,” this AD requires compliance before the accumulation of 5,000 total flight cycles since the date of issuance of the original Israeli airworthiness certificate or the date of issuance of the original Israeli export certificate of airworthiness.

Although the service information referenced in CAAI AD ISR-I-57-2020-06-01 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, Large Aircraft Section, 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 Large Aircraft Section, 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, Large Aircraft Section, International Validation Branch, FAA; or CAAI; or CAAI's authorized Designee.
