 10. Flap Track Fairing Removal (Fig. 201)
__________________________
 A. General
 (1)  When you cannot extend the trailing edge flaps because of failure of a transmission or other flap drive component, you must remove the flap track fairings to get access to the failed component. This is a general procedure to remove the inboard or outboard fairings. It can be necessary to change the procedure for the specific component failure.

You cannot use the usual equipment to remove the fairing with the flaps retracted. Use a maintenance stand or other equipment to hold the fairing. The inboard fairing weighs approximately 110 pounds and the outboard fairing approximately 80 pounds.

 (3)  
After you repair the flap system, you can install the flap track fairings with the usual installation procedures. Refer to 27-51-26/401 for the inboard flaps or 27-51-31/401 for the outboard flaps.
