Canopy Side Windows on the 4 Place
Window Replacement
The AA-5x canopy side windows slide in from the bottom, and that means that step one is to remove the canopy assembly from the plane. To do this remove the bottom row of screws on the canopy. There are 2 shims at the aft edge held on by the last 2 screws on each side, be sure to keep them for re-installation.
After all the bottom row of screws is out, the canopy can be lifted straight up and off of the plane. This ought to be done by at least 2 people, and 3 would offer an additional level of safety. With a helper on the opposite wing root, lift the canopy straight up, taking care not to scratch the quarter windows with the sharp corners at the aft edge of the canopy. Once the canopy is above the turtledeck height, carefully hand it over to one person on the wing root. The other person then gets off the wing and comes to the trailing edge of the wing so that the person holding the canopy can hand it down. The canopy should be placed upside down on a padded surface. A packing blanket or sleeping bag folded a few times is a good pad on the ground.
Taking the interior plastic trim out
The windows are clamped to the frame at the "bottom" by another row of screws that hold the bottom of the window frame in place. Remove the screws and the stiffener can be removed. The interior plastic is sandwiched between the stiffener and the outside canopy. The interior plastic can now be removed. There are screws and rivets along the front edge of the plastic under the canopy bow seal. Remove the seal. Its probably old and in need of replacement anyway. A stiff bladed putty knife can help shear the glue that holds the seal in place. Use 3M General Purpose Adhesive Cleaner to soften the glue and remove it from the bow. Under the glue the pull rivet heads and the screws can be found.
Remove the screws and carefully drill out the rivets. Best practice is to use a small punch to tap the rivet stem back out of the way and then drill the rivet using the mandrel hole as a pilot. Use a 1/8th inch drill bit to avoid drilling the holes over-size.
Patience is a virtue! <G>
