7.10.1. Fuel Shut-off Valve
WARNING
THE FUEL SHUT-OFF VALVE SHOULD ONLY BE CLOSED
FOR EMERGENCIES OR FUEL SYSTEM MAINTENANCE.
There are two different versions of fuel shut-off valves in the DA20-C1.
Version 1
The fuel shut-off valve is located on the cabin side of the firewall and is controlled by a handle
on the right side center pedestal. To activate the fuel shutoff valve, lift the handle release lock
and pull the handle out. In the open position the knob is in. In the closed position the knob is
out.
Version 2
The fuel shut-off valve is integral to the maintenance drain manifold, located below the fuel tank.
It is actuated by the center console mounted rotary lever, via a rigid pushrod. To activate the
valve, rotate the lever clockwise from OFF to ON or lift the lockout knob and rotate the lever
counterclockwise from ON to OFF. The safety lockout knob prevents accidental actuation of the
valve.
7.10.2. Tank Drain
To drain the tank sump, activate the spring loaded drain by pushing the brass tube in with a
drain container. The brass tube protrudes approximately 1 1/6 in (30 mm) from the fuselage
contour and is located on the left side of the fuselage, approximately at the same station as the
fuel filler cap.
7.10.3. Fuel Filter Bowl
The fuel filter bowl is between the tank and the fuel pump. The bowl acts as a trap for sediment
and water that has entered the fuel line from the tank.
7.10.4. Fuel Filter Bowl Drain
The filter bowl drain is next to the fuel tank drain. It operates in the same manner as the fuel
tank drain.
7.10.5. Fuel Dipstick
A fuel dipstick, P/N 22-2550-14-00, is supplied with all aircraft to permit direct measurement of
fuel level during the preflight check. On serial numbers C0056, C0066, C0067 and C0069 use
fuel dipstick P/N 22-2550-17-00.
NOTE
Revision 25
Electric fuel gauges may malfunction. Check fuel quantity with
fuel dipstick before each flight.
