7.2.3 UNDERCARRIAGE
The landing gear is of the conventional tail-dragger configuration. The
main gear and tail wheel are electrically repositionable for water
operations. The main gear swings upward and the tail wheel swings
forward and upward when retracted.
CAUTION: The tail wheel is extended downward by a stainless steel
cable linked to the undercarriage system. Care should be taken when
moving the aircraft backward, as damage may result if excessive
pressure is exerted on the cable.
WARNING - WATER LANDINGS: Pilots should make absolutely certain
that the undercarriage is in the “UP” and locked position at all times, when
carrying out water landings. Serious aircraft damage and personal injury
may result if this is not observed.
7.2.3.1 ELECTRIC LANDING GEAR
The landing gear may be operated at any speed. The landing gear is
operated by two linear actuators, each driving one of the legs. Power
comes directly from the battery through the cockpit landing gear reversing
switch and then divides through the left and right 10 a. circuit breakers to
the individual actuators. Internal switches in the actuators determine the
range of operation. The circuit breakers are of the pull-able type allowing
movement of the legs individually. The landing gear should only be
operated while the aircraft is in the air or water deep enough that the
wheels will not touch solid ground.
CAUTION: UNDER NO CIRCUMSTANCES SHOULD THE LANDING GEAR BE
USED TO LIFT THE PLANE. Damage to the aircraft will occur.
There are multiple micro-switches associated with the landing gear
mechanism. These switches do not play a role in the operation of the
landing gear. They do indicate to the pilot the position of each gear leg
via the four lamps surrounding the landing gear switch as well as
indicating the position to the EFIS landing gear alert feature.
Fault? If both of the landing gear legs fail to move and stay in the down
position, a safe landing on a runway is advised. If both fail in the up
position, a water landing is best although a landing on soft smooth ground
would minimize or totally avoid damage to the hull. If one gear stays up
and one down, a landing on soft smooth ground is advised.
