3.3.4 ENGINE FAILURE IN FLIGHT
WARNING
Control over the flight attitude has priority over attempts to solve the current problem ("first fly the airplane").
NOTE
As long as there is no major mechanical engine defect, the propeller will continue to windmill.

If the Remaining Altitude is Sufficient for an Restart Attempt:
Try to restart the engine, refer to 3.3.5 - RESTARTING THE ENGINE IN FLIGHT.
If the Remaining Altitude is NOT Sufficient for an Restart Attempt:
Carry out an emergency landing in accordance with 3.7.1 - EMERGENCY LANDING WITH ENGINE OFF.

3.3.5 RESTARTING THE ENGINE IN FLIGHT
NOTE
With a failed engine the propeller continues to windmill. A stopped propeller indicates a major mechanical engine defect. Starter assisted restart shall not be considered.
Maximum restart altitude: |

16,400 ft |
pressure altitude . . . . . . . . . . . . . . |
for immediate restarts |
10,000 ft |
pressure altitude . . . . . . . . . . . . . . |
for restarts within two minutes |
NOTE
If the engine is allowed to cool down for more than two minutes, a successful restart may not be possible.

NOTE
The glide ratio is 9.7; i.e., for every 1000 ft (305 m) of altitude loss the maximum horizontal distance traveled in still air is 1.59 NM (2.94 km). During this the propeller will continue to windmill.
Carry out an emergency landing in accordance with 3.7.1 -
EMERGENCY LANDING WITH ENGINE OFF.
CAUTION
Engine restart following an engine fire should only be attempted if it is unlikely that a safe emergency landing can be made. It must be expected that engine restart is impossible after an engine fire.

3.3.6 DEFECTIVE RPM REGULATING SYSTEM
WARNING
In case of defective RPM regulating system, reduced engine performance should be anticipated.
CAUTION
Following a failure of the governor the RPM should be adjusted with the POWER lever.
CAUTION
The POWER lever should be moved slowly, in order to avoid over-speeding and excessively rapid RPM changes. The light wooden propeller blades produce more rapid RPM changes than metal blades.

(b) Propeller Overspeed
CAUTION
Climb performance will be reduced.
NOTE
The propeller now works like a fixed pitch propeller. RPM is controlled by the engine power setting. Flight to the nearest airfield can be continued with a lower power setting and at a lower airspeed. Climb and go-around may not be possible under all conditions.

NOTE
If selecting ECU A or ECU B does not solve the problem, % switch back to AUTO. Keep controlling the climb/sink rate with
the POWER lever and do not exceed 2300 RPM.
