3.7.2
Engine failure in flight
Should the engine fail in flight, check:
Sufficient fuel quantity?
Fuel shut-off valve OPEN?
Circuit breaker “Fuel pump“ CLOSED?
Circuit breaker “Power plant system” CLOSED?
Should it be impossible to restart the engine, continue the flight with retracted
power plant.
Emergency procedure for starting the engine in flight despite a defective starter
motor
Follow the normal checklist until the item “depress starter button”
Set flaps at „0“ and accelerate to 160 km/h (86 kt, 99 mph) so that the engine revs
will quickly build up (with audible prop noise).
Maintain speed until the engine has started. Then pull up with about 2 g and
reduce speed to the desired climb flight speed.
If possible, increase the throttle carefully during the pull up with reducing airspeed
to ensure sufficient lubrication of the engine.
CAUTION:
Observe the speed limits of the engine!
The loss of height from the moment of acceleration to the point where the aircraft
is leveled off is in the order of 150 m to 200 m (490 ft – 660 ft). For this reason,
this emergency procedure should not be applied at altitudes below 400 m (1312 ft)
above the ground.
Icing of induction system
Form experience gained to date, no induction system icing has yet occurred on the
engine model installed.
CAUTION:
Should the engine fail in flight due to the lack of fuel or a defect., retract the power
plant as quickly as possible to avoid any unnecessary deterioration of the flight
performance (for more precise date refer to section 5).
