FLIGHT CONTROL LATERAL TRIM CORRECTION - ADJUSTMENT TEST
________________________________________________________
General
_______
A. This procedure supplies the data that is necessary to adjust the trailing edge flaps for straight and level flight. The procedure will decrease the quantity of rudder and aileron trim that is needed during flight at a constant speed.
B. This adjustment installs and/or removes shims from each outboard-flap-track location for each of the two outboard flaps. The installation of more shims will move the flap trailing edge up. The removal of shims will make the flap trailing edge move down.
