Task Instructions
1. Due to the slight compression of the strut on installation, it is easiest to first install the strut’s ball stud as a separate part, then install the strut itself. Be sure to locate the ball end of the stud facing outboard. Use LOCITITE® 243™ on the threads of the ball stud. Torque the ball stud nut to 50 in-lbf.
2. Ensure that there are two NAS1149C0463R washers on the threaded stud that attaches the cylinder end of the strut to the structure, prior to strut installation.Figure 127

3. Slide the cylinder end fitting of the strut onto the threaded stud, followed by one NAS1149C0432R washer and an MS21043-4 nut. Use a 5/16 socket wrench to torque the nut to 30-40 in-lbf.
4. Slightly compress the strut by hand and snap its socket end onto the ball stud.
5. Slide the ball retaining clip into the locked position.
6. Deflect the flap surface by hand while watching the gas strut and flap pushrod move. Verify that there is no binding or interface.
7. Check for proper flap operation. (Inspect Flap Rigging) Install the wing fold access panel.
Verification Method
To verify, check the flap rigging. (Install Flap Gas Strut) Fully actuate the flap through its full range of motion, both up and down. Visually inspect the system for proper function and security.
