Emergency Landing Gear Extension (continued)
[ ] Set the landing gear control switch to ‘Down’[ ] Pull the circuit breaker labelled ‘Ldg Pwr’[ ] Remove the centre cover by turning its quick fastener[ ] Lift and rotate the crank handle to engage it in the slot of vertical shaft[ ] Turn counter clockwise the hand crank (27 turns)[ ] Check the green indicator lights and/or the mechanical gear position indicator
Warning: The emergency hand control must not be used in flight to retract the landing gear
Note: In FSX instead of the above procedure, hit ‘Ctrl-G’ repeatedly until green gear-down lights illuminate. Failure of Landing Gear Electrical System on Take-off
In case the landing gear electric retraction manoeuvre cannot be accomplished after take-off, two cases can appear:
1 Green gear lights ‘on’ (landing gear ‘down and locked’)In this case, turn the landing gear control switch to ‘Down’ and land as soon as possible.
2 Red gear light ‘on’ (landing gear which does not reach ‘up and locked’)In this case, return the control switch to ‘Down’. If the green lights come on again, land as soon as practicable. If the green lights do not come on again, perform the emergency extension manoeuvre prescribed in ‘Emergency Landing Gear Extension’ procedure, and land as soon as possible.
Balked Landing
[ ] Apply full throttle[ ] Check air speed[ ] Retract the landing gear[ ] Flaps - as necessary[ ] Trim the aircraft for climb
Recovery After Stall
The stall recovery procedure is as follows:
Push the stick forward and apply engine power, allowing air speed to increase (5—10 Kts above stall speed) then pull gently to regain level flight.
Note: At maximum weight the loss of altitude during the stall is about 200—250 ft.
Recovery From Spin
The following normal recovery technique from an intentional or unintentional spin is sufficient to obtain an immediate recovery:
Apply full opposite rudder and immediately after move the control stick forward to the central position.
Note 1: Unintentional spin: In one turn normal spin at maximum weight (2430 lb) the loss of altitude including recovery is about 1200 ft, and the speed at the end of recovery is approximately 122 Kts.
Note 2: Intentional spin: In a six turns normal spin at maximum weight (2205 lb) the loss of altitude including recovery is about 4500 ft, and the speed at the end of recovery is approximately 165 Kts and the maximum flight load factor during the manoeuvre is 4 g.

Warning - Do not attempt to restart the engine in flight.
Electrical System
All electrical system circuits are protected by circuit breakers which automatically break the circuit in case of overloads or short circuits. If a circuit breaker pops out do not attempt to reset the breaker, unless the relevant circuit is indispensable for the flight. In such case, allow sufficient time for cooling, then press the circuit breaker button to reset the breaker, but turn off the controlling switch for that circuit and , if necessary, land as soon as possible.
Generator Failure
In case of generator failure, indicated by negative reading on Ammeter, proceed as follows:
[ ] Unnecessary electrical equipment ..........................................................................................................[ ] ALT switch ................................................................................................................................................[ ] Land as soon as possible
Note: The system endurance, with only a fully charged battery may range from about 30 minutes with night flight essential loads, to more than 1 hour, with daytime essential loads.
Fuel System
In case of loss of fuel pressure, turn auxiliary fuel pumps ON and reduce engine power until operating condition will become normal.
Emergency Landing Gear Extension
If the green landing gear indicator lights do not come on and the mechanical position indicator does not move to its full out position, this means that the electrical landing gear actuating systems has failed to operate. In this event, operate the emergency control handcrank located between the pilot's seats in accordance with the following instructions: (Continued on next page)
