Page 11-2, step 3. calls for the temporary attachment of the elevator to the Horizontal Stab. There should be a 1/8" gap between the outboard edge of the H.S. and the Inboard edge of the elevator counterbalance arm. I have been unable to achieve a consistent 1/8" gap along the entire counterbalance arm. I have an 1/8" at the trailing edge of the elevator but only a 1/16" at the oposite end out by the counterbalace weight. Any suggestions on how to achieve a consistent 1/8" gap would be much appreciated.
