Section 3 Emergency procedures
new subsection
3.19 Emergency extension of the electrically operated main landing gear
If extending the landing gear via the electrical system is not possible, the landing
gear may be extended manually. The extension force is produced by a gas strut.
For emergency extension pull on one of the 2 black-red emergency extension
handles (located at the left hand fuselage wall, one in each cockpit), pull the
handle until the landing gear is fully extended. The travel is about 15 mm (.6
in.), the extension time about 2 seconds. During extension the centre (red) LED
is shining. When the landing gear is fully extended the lower green LED also
starts shining.
Warning: Don't let the handle go before the green LED starts shining. If you
don't pull for long enough the landing gear will rest in a position not locked
over centre and will be destroyed at touch down.
Caution: If you execute the emergency extension at high airspeed it may take a
longer time until the landing gear is fully extended. You should shorten the time
by reducing the airspeed.
Caution: If emergency extension was necessary check the system to detect the
failure and repair the system.
Resetting the system for normal operation see section 4.5.12.3.
3.20 Incompletely retracted electrically operated main landing gear
If the landing gear is not locked the centre (red LED) starts blinking approx. 22
seconds after the start of the retraction.
In this condition the retraction mechanism may be damaged with g-loads
exceeding 4 g.
Instruction 1: Extend and retract the landing gear again.
Instruction 2: If instruction 1 was not successful extend the landing gear and
land as soon as possible to fix the problem. For the remainder of the flight, don't
fly faster than 150 km/h (81 kts.) and avoid abrupt manoeuvres.
