Landing gear emergency extension
Landing gear controler:
(1) – „Reset“ button
(2) – Three red lights for „GEAR UP“ position
(3) – Three green lights for „GEAR DOWN“ position
(4) – Red light „AGREGAT“
(5) – Switch for retraction and extension of landing gears
This procedure is necessary to use if you don‘t see the three green lights on the
„
Landing gear
controler“ during the landing gears extension. The hydraulic system for landing gears opening is
programmed to run 30 sec. If after this period the „Landing gear controler“ don’t indicate all three landing
gear sensors in the right position, the red light „agregat“ (4) start flashing and the system will set himself
into „standby status“. In this case push once again the button „Reset“ (1) on the „Landing gear
controler“ and the system will start new cycle of landing gears opening. If the three green lights appears,
landing gears are open and in the right position. After landing of aeroplane is necessary make detail
inspection of undercarriage opening system and find a cause of the defect!
If after reset of „Landing gear controler“ you don’t see the three green lights you must use the hand
pump for „Emergency releace of gears“ (see chapter 7.3 pos.22) for manuel opening of landing gears –
follow next steps:
1.
Check fuel level - for estimating the time, you have for an emergency landing
2.
Airspeed 120 km/h (65 kts)
3.
Switch (5) of „Landing gear controler“ toggle to position „gear down“
4.
Landing flaps open to „15°“
5.
By the right hand, hold the control stick to fly the plane and by the left hand to grab the
handle of hand pump.
6.
By pulling pump handle up, tear off safety wire!
7.
Start pumping down untill the hand pump stops (min.35 cycles of compression) and until the
three green lights appears on „Landing gear controler“- it indicate, that landing gears are
open and in the right position.
8.
When appears three green lights on the „Landing gear controler“ you can safely land.
9.
If THREE green lights will not appears, ask air traffic control tower for visual inspection of
landing gears position. If the air traffic control tower confirm you right position of all three
open landing gears you can safely land.
10.
If the air traffic control tower does not confirm you right position of all three landing gears, is
the best solution retract all wheels and make emergency landing without landing gears.
