LANDING WITHOUT ELEVATOR CONTROL
Trim for horizontal flight with an airspeed of approximately 65 KIAS and
flaps set to 20° by using throttle and elevator trim controls. Then
do not
change the elevator trim control setting; control the glide angle by
adjusting power.
During the landing flare (round-out), the nose will come down when
power is reduced and the airplane may touch down on the nosewheel
before the main wheels. When in the flare, the elevator trim control
should be adjusted toward the full nose up position and the power
adjusted at the same time so that the airplane will rotate to a horizontal
attitude for touchdown. Close the throttle at touchdown.
FIRES
Improper starting procedures involving the excessive use of auxiliary
fuel pump operation can cause engine flooding and subsequent
collection of fuel on the parking ramp as the excess fuel drains
overboard from the intake manifolds. This is sometimes experienced in
difficult starts in cold weather where engine preheat service is not
available. If this occurs, the airplane should be pushed away from the
fuel puddle before another engine start is attempted. Otherwise, there
is a possibility of raw fuel accumulations in the exhaust system igniting
during an engine start, causing a long flame from the tailpipe, and
possibly igniting the collected fuel on the pavement. If a fire occurs,
proceed according to the checklist.
Although engine fires are extremely rare in flight, if a fire is
encountered, the steps of the appropriate checklist should be followed.
After completion of the checklist procedure, execute a forced landing.
Do not attempt to restart the engine.
The first sign of an electrical fire is usually the smell of burning
insulation. The checklist procedure should result in the elimination of
the fire.
