## The airworthiness directive

75-23-03 ALEXANDER SCHLEICHER SEGELFLUGZEUGBAU: Amendment 39- 2414. Applies to Ka2B, Ka6, Ka6B, Ka6BR, Ka6C, Ka6CR, K7, K8, and AS-K13 gliders all serial numbers, certificated in all categories.

Compliance is required as indicated.

To prevent structural failure of the elevator and loss of elevator control accomplish the following:

  (a) Within the next 10 hours' time in service after the effective date of this AD, unless already accomplished, remove the elevator from the glider and visually inspect the glue joint between nose rib No. 1 and the nose plywood skin on both elevator halves by probing with a small penknife.

  (b) If insufficient glue adhesion is determined in accordance with good aeronautical practices, before further flight, remove elevator rib No. 1 in its entirety, prepare for new glue joint by roughing the surfaces to be glued, reinstall rib No. 1 by regluing, and cover joints between rib No. 1 and nose skin with fabric to protect joint against moisture.This amendment becomes effective November 14, 1975.
