What to do
Operators of GALP model G200 aircraft must remove both left and right wing flap fairings, inspect, and reseal the fillet seal as specified in Gulfstream Service Bulletin No. 200-57-426. This action must be completed at the next suitable planned maintenance inspection within 24 months from the effective date of February 15, 2024, if not already done.
Summary
Airworthiness Directive ISR I-57-2021-12-4R1 issued by the State of Israel Civil Aviation Authority addresses the repair of wing flap fairing seals on GALP model G200 aircraft, serial numbers 004 through 250. The directive mandates inspection and resealing of the fillet seal between the wing structure and flap fairings to prevent flap fairing debonding, moisture intrusion, and corrosion of the wing lower skin at rib 3 and rib 11.
What changed
This revision updates the compliance time from the initial issue of AD ISR-I-57-2021-12-4. The original requirements remain the same, focusing on removing left and right wing flap fairings, inspecting, and resealing according to Gulfstream Service Bulletin No. 200-57-426 dated January 1, 2022, or later approved revisions.
Why it matters
This directive is critical for maintaining the structural integrity of the GALP G200 wings by preventing corrosion and damage caused by moisture intrusion. Compliance ensures continued airworthiness and safety, reducing the risk of costly repairs or operational disruptions for operators and maintenance organizations.
