Lift Detector Adjustment; Flap Rigging Tool View - Piper PA-44-180 SEMINOLE Maintenance Manual

ADJUSTMENT OF LIFT DETECTOR.
The lift detector switch is adjusted at the factory when the airplane is test flown. and should not require any
further adjustment during the normal service life of the airplane. Should some type of service on the wing
require removing the switch, the following instructions will help in positioning the switch at the proper position.
Loosen the two Philip's head screws: one on either side of the vane. If the stall warning comes on to late
move the switch up. If the stall warning comes on to early. move the switch down. Tighten the screws after
making any adjustments.
NEVER TRY TO ADJUST THE SWITCH BY BENDING
THE VANE.
The only way to test the accuracy of the setting is to fly the airplane into a stall condition and note the
speed at which the stall warning comes on. The stall should be made with the flaps and landing gear up and
power off. It may be necessary to make several test flights and alternate adjustments before the desired setting
is obtained. The stall warning should come on not less than five or more than ten miles per hour before the
actual stall occurs.
