AIRPLANE FLIGHT MANUAL
CAUTION
Whenever the gas generator fails to light up within 10 Seconds
after moving the fuel lever to the LOW IDLE / GROUND IDLE
position, cut off fuel, starter, and ignition. Allow a 30 second fuel
draining period followed by a 15 second dry motoring run before
attempting another start. If for any reason a starting attempt is
discontinued, allow the engine to come to a complete stop and
then accomplish a dry motoring run. (See the following Section.)

DRY MOTORING RUN:
The following procedure is used to clear an engine at any time when it is deemed
necessary to remove internally trapped fuel and vapor or if there is evidence of a fire
within the engine. Air passing through the engine serves to purge fuel, vapor, or fire
from the combustion sections, gas generator turbine, power turbine, and exhaust system.

minutes.)

TAXI
The Beta Region of the throttle quadrant may be utilized for taxing. Push the stick full
forward to unlock the tailwheel.
BEFORE TAKE-OFF:
Before proceeding with a ground run-up, be sure that the propeller system is purged, by
feathering the propeller once or twice with the Power Lever in the Idle Position.
The following procedures should be used to check the Propeller Overspeed Governor:
1. Place the propeller lever in full increase RPM (forward) position.
2. Increase RPM with the power lever to at least 2100 RPM.
3. Momentarily exercise the prop test switch and note a small decrease in the RPM
(2025 ± 20). This checks the prop overspeed governor.
CAUTION
HOLD the Elevator Control firmly FULL UP
during all high power ground operation to keep
the airplane from nosing over.
4. Flight Controls – CHECK free and full travel.
5. Elevator Tab – SET for take-off
6. Flaps – As required
7. Fuel Lever – HIGH IDLE / FLIGHT IDLE (check, 68% Ng).
8. Fuel Aux. Pump – ON

10. Rear Seat Occupant – CONFIRM ready (Dual Cockpit Only)
11. Prior to flights apply take off power and read the filter condition indicator. If the
needle enters the red arc, do not fly until the filter element has been cleaned.
TAKE-OFF:
1. Brakes – RELEASE
2. Power Lever – ADVANCE. Do not exceed engine operational limitations. (See the
Limitations Section)
