DURING FLIGHT
In case that one tank was flown empty, at the first signs of
insufficient fuel feed proceed as follows:
(1) Fuel Shut-off Valve – OPEN (push full in)
(2) Immediately switch the Fuel Selector to BOTH position
(3) Electric Fuel Pump – ON
(4) Check the engine (engine parameters, airspeed/altitude
change, whether the engine responds to changes in the
Thrust Lever position).
(5) If the engine acts normal, continue the flight and land as
soon as possible.
RESTART AFTER ENGINE FAILURE
Whilst gliding to a suitable landing strip, try to determine the
reason for the engine malfunction. If time permits and a restart
of the engine is possible, proceed as follows:
(1) Airspeed between 65 and 85 KIAS (max. 100 KIAS)
(2) Glide below 13,000 ft
(3) Fuel Shut-off Valve – OPEN (push full in)
(4) Fuel Selector switch to BOTH position
(5) Electric Fuel Pump – ON
(6) Thrust Lever – IDLE
(7) Engine Master (“IGN“ resp.) OFF and then ON
(if the propeller does not turn, then additionally Starter ON)
 Note: Running a tank dry activates both FADEC
warning lights flashing.
 WARNING: The high-pressure pump must be checked
by an authorized service center before the
next flight.
