CAUTION
The anchor tab of the force applicator can be bent if the knob that applies
tension to the transducer mounting plate is over tightened. Use care when
installing the force applicator to prevent damage to the anchor tab. Refer
to the data supplied with the force applicator.
6. Install the 1952-3 gauge (2 to 15 gram scale), in the force applicator (see Figure 7-16) onto the
left wing in accordance with the manufacturer's instructions. Refer to the data supplied with the
force applicator. The force arm must be positioned so that the applied force is within 1/32 inch of
the transducer vane tip. Forces applied forward or up will be classified as minus values. Forces
applied aft or down will be classified as plus values. Make sure that the vane is free to move with
the force applicator.
7. Apply external power to the aircraft.
8. Place the BATT master switch to the ON position.
9. Verify the STALL WARN circuit breaker on the copilot circuit breaker panel is set.
WARNING:
Make sure that all personnel are clear of the flap area before proceeding
with these procedures.
10. Flaps retracted (Pot 0) measurement
a. Run the flaps to the full UP position.
b. Install voltmeter leads between TP5 (Hi) and TP2 (Lo), TP6 (Hi) and TP2 (Lo) on the
SK100360 Breakout Box. Ensure that 28 VDC is not present. If the flap information is
incorrect, troubleshoot in accordance with King Air 200 Series Maintenance Manual
procedure 27-31-00.
c. Using the force applicator, slowly apply a negative Tip Gram (TG) force forward (UP)
on the vane until the stall warning horn sounds. Record the flaps retracted (Pot 0) TG
value.
d. Return the force on the vane to 0 TG.
11. Approach Flaps (Pot 1) measurement
a. Run the flaps to the APPROACH position.
b. Install voltmeter leads between TP5 (Hi) and TP2 (Lo), TP6 (Hi) and TP2 (Lo) of the
SK100360 Breakout Box. Ensure that 28 VDC is ONLY present between TP5 and
TP2. If the flap information is incorrect, troubleshoot in accordance with King Air 200
Series Maintenance Manual procedure 27-31-00.
c. Using the force applicator, slowly apply a negative TG force forward (UP) on vane
until the stall warning horn sounds. Record the approach flaps (Pot 1) TG value.
d. Return the force on the vane to 0 TG.
12. Flaps Extended (Pot 2) measurement
a. Run the flaps to the FULL DOWN position.
b. Install voltmeter leads between TP5 (Hi) and TP2 (Lo), TP6 (Hi) and TP2 (Lo) of the
SK100360 Breakout Box. Ensure that 28 VDC is ONLY present between TP6 and
TP2. If the flap information is incorrect, troubleshoot in accordance with King Air 200
Series Maintenance Manual procedure 27-31-00.
c. Using the force applicator, slowly apply a negative TG force forward (UP) on the vane
until the stall warning horn sounds. Record the flaps extended (Pot 2) TG value.
d. Return the force on the vane to 0 TG and remove the force applicator from the aircraft.
