Airworthiness Directive · Amendment 39-22079 · Elevator, spar/rib structure
Alexander Schleicher GmbH & Co. Segelflugzeugbau Gliders
This AD applies to Alexander Schleicher GmbH & Co. Segelflugzeugbau Model Ka2B, Ka 6, Ka 6 B, Ka 6 BR, Ka 6 C, Ka 6 CR, K 7, K 8, K 8 B, and AS-K 13 gliders, all serial numbers, certificated in any category.
The FAA is superseding Airworthiness Directive (AD) 75-23-03 for all Alexander Schleicher GmbH & Co. Segelflugzeugbau (Alexander Schleicher) Model Ka2B, Ka 6, Ka 6 B, Ka 6 BR, Ka 6 C, Ka 6 CR, K 7, K 8, and AS-K 13 gliders. AD 75-23-03 required visually inspecting the glue joint between the elevator nose rib number 1 and the nose plywood skin and replacing the glue joint if insufficient glue adhesion was found. Since the FAA issued AD 75-23-03, the European Union Aviation Safety Agency (EASA) superseded prior EASA ADs for the unsafe condition on these products. This AD adds the Model K 8 B gliders to the applicability and requires repetitively inspecting the glue joint at elevator rib number 1 and repairing any damage found. The FAA is issuing this AD to address the unsafe condition on these products.
Within 30 days after the effective date of this AD and thereafter at intervals not to exceed 12 months or 500 flight cycles, whichever occurs first, inspect the glue joint between elevator rib number 1 and the plywood skin for damage by following section 3 of Alexander Schleicher GmbH & Co. Segelflugzeugbau Appendix 01-2021, Flight and Operating Manual, dated March 1, 2021. For purposes of this AD, a flight cycle would be counted anytime the glider launches and then lands. If there is any damage on the glue joint, repair before further flight.
The aircraft, engines and makers this AD names, by the model designations in its text. A model listed here may still be outside the AD's serial ranges.
