The fans permit high speed cooling of the brakes. They thus decrease the turn around time of the aircraft if you make short flights with high energy braking. One fan is installed on each wheel of the main gear. Each fan includes: - a motor, - an impeller, - a shroud with a debris guard. The fan motor is installed in the wheel axle, where an adaptor assy holds it in position. The motor drives the impeller which makes a flow of air from the heat pack to the exterior through the debris guard. The tachometer drive shaft passes through the hollow shaft of the fan motor. The shroud drives the tachometer.
B. Electrical Installation (Ref. Fig. 003) The fan motor is of the three-phase type. The two motors in each twin-wheel axle have a common supply. With the landing gear downlocked, you push the illuminated pushbutton switch 4GS to start the fans.

The fans must be started as soon as the HOT legend of the pushbutton
switch comes on.
Illumination of the HOT legend shows that the temperature of one brake
minimum is above the brake overheat threshold.
The control relays are in the relay box 103VU and the circuit breakers on
the panel 121VU.
