78-14-03: Horizontal Stabilizer

78-14-03 GLASER-DIRKS: Amendment 39-3255. Applies to Model DG-100 gliders, certificated in all categories. NOTE: This AD does not apply to the DG-100G glider. Compliance is required within the next 20 hours time in service after the effective date of this AD, unless already accomplished. To reduce the possibility of the horizontal stabilizer not being fully seated and secured to the vertical stabilizer during assembly, accomplish the following: (a) Modify The horizontal stabilizer attachment fitting by adding a plastic pin extension in accordance with Glaser-Dirks Technical Note No. 301/5 dated February 2, 1978, or an equivalent approved by the Chief, Aircraft Certification Staff, Europe, Africa, and Middle East Region. (b) Revise the Model DG-100 Service Manual as follows: (1) By adding a sentence to item 5 on page 18 relating to mounting the stabilizer that reads-- "The cockpit trim control should be in the aft position". (2) By adding to the amendments on page 2 the phrase-- "Assembly of the all flying tailplane, page 18". This amendment becomes effective July 11, 1978.
