The FAA amends § 39.13 by adding the following new airworthiness directive: 2023-06-09 Gulfstream Aerospace LP (Type Certificate Previously Held by Israel Aircraft Industries, Ltd.): Amendment 39-22395; Docket No. FAA-2022-0994; Project Identifier MCAI-2022-00052-T.

(d) Subject Air Transport Association (ATA) of America Code 57, Wings. (e) Unsafe Condition This AD was prompted by reports that wing flap fairing debonding and corrosion were discovered at the lower skin of rib 3 and rib 11 on both wings. The FAA is issuing this AD to address flap fairing debonding and moisture intrusion that might lead to lower wing skin corrosion and cracking on both wings, and reduced structural integrity of the wings.
