Brief Description: Horizontal Stab, Right & Left Elevator Assembly
Completed the following tasks on the elevators and the horizontal stabilizer: * Finish tightening E-714 (counter balance weight) on right elevator. * Install the rod end bearings as shown (right elevator). * Make a preliminary check to see that the elevator will swing through its full up and down travel without any interference’s. It was necessary to remove the small portion of the bottom flange of HS-603PP to allow the elevator horns enough swing. * Align the trailing edge on the extended chord line of the stabilizer: "in trail." The counterbalance arm should align evenly with the stabilizer. Secure the elevator in this position. * Fabricate a “drill bushing” with an outside diameter of 1/4" and an 3/32" inside diameter. Any small metal tube can be used. The bushing will protect the VA-146 hinge bearing from the drill bit and act as a drill guide to locate and drill the hole in WD-605-1-R for the bolt that attaches the horn to the center bracket. * Insert the drill bushing into the HS-411PP hinge bracket/bearing assembly. Using the drill bushing as a drill guide, pilot drill WD-605-1-R to #40. * Remove the elevator from the horizontal stabilizer and carefully drill the hole in the WD-605-1-R horn to final size. * Repeat the above steps for the left elevator assembly. * Install the elevators on the horizontal stabilizer and make a check for alignment. There should be no binding in the hinge line.
