Description
The smoke system consists of two glass fiber tanks in each wing with collapsible silicone bladders inside
(36 liters /7.4-gal total capacity), an electrical pump is located in a compartment under the right front leg
support. Oil lines from each tank route into a T-fitting under the front seat, from there one line to the pump,
from there via a bulkhead fitting through the firewall into the exhaust collectors.
To fill the system, a T-fitting and a check valve are installed between the pump and the firewall bulkhead
fitting. An oil line routes from the T-fitting to a pneumatic connector, installed in the bottom of the fuselage,
accessible from underneath the plane, just aft of the right landing gear leg.
The Circuit Breaker Switch marked “SMOKE REFILL” reverses the polarity of the pump to fill or use the system.
The rocker switch on the throttle activates the pump.
The system can be deactivated by pulling the Button Circuit Breaker marked “SMOKE”.
