## The airworthiness directive

75-16-19 FLUG-und FAHRZEUGWERKE A.G.: Amendment 39-2293. Applies to Diamant HBV gliders, all serial numbers, and Diamant 16.5 gliders, S/N 011 through 069, except 030, 031, 036, 058, 067, and 068, certificated in all categories.

Compliance is required within 25 hours' time in service after the effective date of this AD, unless already accomplished.

To prevent jamming of the rudder, accomplish the following:

  (a) Visually inspect and measure the fin fairing overlap of the rudder nose for right full rudder to assure an overlap of more than 0.4 inc. (10 mm) in accordance with Flug-und Fahrzeugwerke A.G. Service Bulletin No.2, dated May 15, 1970, or an FAA-approved equivalent.

  (b) If fin fairing overlap measured in accordance with paragraph (a) of this AD is less than 0.4 in. (10 mm), modify (lengthen) the rudder nose by bonding fiberglass strips to the nose in accordance with Flug-und Fahrzeugwerke A.G. Service Bulletin No.2, dated May 15, 1970, or an FAA-approvedequivalent.

This amendment becomes effective August 12, 1975.
