Compliance is required within the next 100 flights after the effective date of this AD, unless already accomplished.

(a) Install an SAE 1024 steel safety brace in the fuselage frame between the airbrake lever bearing and the left diagonal strut in accordance with Step 2 of the paragraph entitled "Instructions" of Schempp Hirth Technical Note 278-17, dated December 8, 1975, or an FAA- approved equivalent.
(b) For the purpose of this AD, a flight is a sequence consisting of a takeoff operation and landing.
