SUPPLEMENTARY INFORMATION:  

REGULATORY TEXT:   75-17-11 ALEXANDER SCHLEICHER: Amendment 39-2313. Applies to ASW 15 gliders, serial numbers 15001 thru 15183, certificated in all categories.

Compliance is required within the next ten hours time in service after the effective date of this AD and thereafter at intervals not to exceed 50 hours time in service from the last inspection until the rudder nose is reinforced in accordance with paragraph (b)(2) of this AD.

To prevent rudder jam due to improper fin-rudder nose clearance, accomplish the following:

(a) Visually inspect the rudder nose for deformation and measure the gap between the fin and rudder. The acceptable gap is between 2 to 3 mm at the lower rudder hinge tapering to an allowable gap of between 1 to 2 mm at the upper end of the vertical fin.

(b) If the measured gap is not within limits, or a deformation of the rudder nose is found, comply with the following:

(1) Reform the rudder nose inward until the gap is within limits by applying heat in accordance with paragraph 1 of the instructions contained in Alexander Schleicher ASW 15 Technical Note 10 dated January 30, 1973, or an FAA-approved equivalent.

(2) Reinforce rudder nose in accordance with paragraph 2 of the instructions contained in Alexander Schleicher ASW 15 Technical Note 10 dated January 30, 1973 and Alexander Schleicher drawing L-272 150.36/37.B1.33, or an FAA-approved equivalent.

This amendment becomes effective August 18, 1975.
