•
Make sure the stabilator
contacts its up and
down stops before the
WD-1210 Control
Column contacts its up
and down stops. If not,
loosen and tighten the
stabilator cable
tensioner barrels an
equal and opposite
amount until the travel
is full and correct. The
control column stops
must limit excessive
forward and aft
pressure. The bellcrank
stops must limit the left
and right control stick
motion. See
Figure 5
.
Figure 5: Control Stops
•
Actuate the vent door on each side of the cockpit and confirm a clear passage.
Actuate the cabin heat push/pull cable, confirm a clear passage to the cabin (when
'On'), and smooth operation. Confirm that the heat door has a tight seal to the
firewall when heat control is in the off position.
•
Test the full motion of each of the engine control cables for smooth operation and
proper operation of the friction (throttle control) or position lock (choke control).
•
Test the operation of the fuel valve. Check the security of the electric fuel pump and
the fuel flow transducer.
•
Inspect the system lines that run along the center, of the bottom skin. Check all
fittings for leaks. The system lines include (from left to right while seated in the
cockpit); electrical wire bundle & static line, fuel return, left brake line, right brake
line, and fuel supply. There must be snap bushings at each bulkhead and clamps or
brackets to hold the lines secure.
•
Test the operation of the brake pedals. Constant pressure must not cause any of the
brake pedals to bottom out. Without pressure, each brake pedal must automatically
return to the original position.
•
The rudder pedals must move opposite and relative to each other with no slack
between them. The rudder stops on the lower rudder hinge must limit the rudder and
pedal travel.
