7.2.4 DRAINS
The A5-B airframe is not entirely water tight. Water that does enter
is directed overboard or into the bilge through a series of drain
paths and holes. Examples of these holes can be seen at the root
end of control surfaces and wing panels. The side nose gear doors
have drain holes. The low point of the firewall beneath the engine
has a drain that is directed through a hose to the exterior of the
aircraft on the right side of the tail boom just aft of the propeller. The
interior fuselage bulkheads have drain passages at their low points
to allow water to flow into the bilge. All drain provisions should be
kept clear to allow water to flow.
7.3 FLIGHT CONTROLS
The primary flight controls consist of the elevator, ailerons, and air
rudder. Secondary flight controls consist of the electrically
controlled trailing edge wing flaps, elevator trim tab, and water
rudder. The flight control system is fully mechanical, providing direct
feedback of control surface loads to the pilot throughout the flight
envelope on the water and in the air.
The rudder pedals are adjustable fore/aft for occupant convenience
and comfort. The pedals are spring loaded in the aft direction and
are released by raising a handle on the outboard, front face of each
seat. Before adjusting the pedals, place one heel on the black
rudder pedal adjustment bumper located between the rudder
pedals at floorboard level. When ready to adjust the pedals, raise
and hold the release handle and then push or release pressure on
the bumper until the desired location is achieved. Releasing the
adjustment lever locks the pedals at the current position. After the
adjustment is complete, ensure that the pedals are locked by
applying pressure to the adjustment bumper. The pedals can be
locked at any location within the rudder pedal adjustment limits.
7.3.1 PITCH TRIM SYSTEM
Pitch trim is achieved through the actuation of a tab incorporated in
the elevator trailing edge. The tab is deflected by an
electro-mechanical actuator powered through a slide switch at the
top of the pilot’s (left) control stick grip. There is no pitch trim control
on the passenger control stick.
