This AD applies to Alexander Schleicher GmbH & Co. Segelflugzeugbau Model ASW-15 gliders, all serial numbers, certificated in any category.
The FAA is adopting a new airworthiness directive (AD) for all Alexander Schleicher GmbH & Co. Segelflugzeugbau Model ASW-15 gliders. This AD results from mandatory continuing airworthiness information (MCAI) originated by an aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI identifies the unsafe condition as wing root damage. This AD requires repetitively inspecting the wing root ribs for cracks, looseness, and damage and replacing any root rib with a crack, a loose rib or lift pin bushing, or any damage. The FAA is issuing this AD to address the unsafe condition on these products.
(1) Within 30 days after the effective date of this AD and thereafter at intervals not to exceed 12 months, inspect all wing root ribs (4 places) for cracks, looseness, and damage, in accordance with the Action section in Alexander Schleicher GmbH & Co. Segelflugzeugbau ASW 15 Maintenance Instruction G, Issue 1, dated June 28, 2021. If there is a crack in any root rib, a loose rib or lift pin bushing, or any damage, before further flight, replace the root rib in accordance with Action paragraph (B) in Alexander Schleicher GmbH & Co. Segelflugzeugbau ASW 15 Technical Note No. 29, dated June 28, 2021, and steps 1 through 7 in Alexander Schleicher GmbH & Co. Segelflugzeugbau ASW 15 Repair instruction exchange of wing root ribs according to TN 29, dated June 28, 2021.
