## The airworthiness directive

Compliance required as indicated.

Cracks have occurred in the forward horizontal stabilizer fitting, above the welded seam on the fuselage side. The cracks are believed to be caused by excessive hardening due to welding.

Within the next 10 hours' time in service after the effective date of this AD, accomplish the following:

  (a) Remove the forward horizontal stabilizer fittings and inspect for cracks with at least a 3-power magnifying glass. Replace cracked fittings with new fittings before further flight.

  (b) Check all fittings for excessive hardness by use of file as specified in Schleicher Special Inspection for Models Ka2B and Ka6 dated July 12, 1961. Replace fittings found to be too hard, with a new part within the next 10 hours' time in service thereafter.
