Task Instructions
1. Locate the ICA008702 wing lock catch housing. It mounts to the wing lock switch plate and contains two opposing spring-loaded balls that pinch a feature in the wing lock handle, thus creating a detent that helps hold the handle in the up and locked position (See Figure 466).

2. Use a 3/16 hex wrench to remove a set screw from one end of the housing. Use care not to lose the spring and ball that lie under the screw.
3. Apply LOCTITE® 243™ to the threads of a 91318A650 hollow-lock set screw.
4. Insert the ball, then the spring into the housing.
5. Install the set screw so that the spring is compressed against the ball and the head of the screw is set to a depth of .06±.01 below flush (see Figure 467).

6. Repeat the above steps for the other set screw in the housing.
Verification Method
From the up and locked position, unlatch the handle locking pawl and pull the handle down. The force needed to displace the handle from the grasp of the lock catch should be 7±2 lbf. Adjust the housing set screws equally, together in or out, to achieve this force.
