4.5.4.2 Stopping and retracting the engine in flight
1. Fly at 85-90 km/h (46-49 kts).
2. Bring the throttle back to idle.
3. Switch off the ignition.
4. The powerplant will be automatically retracted a certain distance to
reduce the rotational forces on the propeller. The propeller will slow
down by itself.
5. The powerplant will be automatically retracted another 5° and the
propellerstopper moves forward in the propeller circle. If the propeller is
already in the position for retraction (close to the stopper) the powerplant
will retract by itself.
To save altitude you may turn the propeller into the position for
retraction (ignition switched off) by pressing the starter button. The
starter motor receives only pulses of electric power to turn the propeller
slowly. As soon as the propeller is in retraction position, the electric
power to the starter motor is cut off.
6. If turning the propeller via the starter motor doesn't work, you may turn
the propeller by flying faster. Watch the procedure in the rear view
mirror.
7. As soon as the propeller is in the position for retraction (close to the
stopper) the powerplant will retract by itself.
8. If the automatic retraction doesn't work, the powerplant may be retracted
via the manual extension-retraction switch.
Caution: It is possible that the propeller might stop just above the propeller
stopper and can press on the stopper during powerplant retraction into the
position where the stopper shall move forward. The stopper can't move forward
and operates the switch in this position. To avoid any damage the powerplant
will not retract completely. To accomplish this the DEI-NT checks within 3
seconds if the switch has been operated. If not, the powerplant will be extended
automatically to the powerplant position where the propeller usually should stop
turning.
Rotate the propeller out of this position by pressing the starter button, further
powerplant retraction is as usual.
Note: only in this special case is it possible to rotate the propeller with the
starter motor in this powerplant position (position where the propeller should
usually stop turning).
