4.7 AMPLIFED NORMAL PROCEDURES (GENERAL)
The following paragraphs are provided to supply detailed information and explanations of the normal
procedures necessary for the safe operation of the airplane.
4.9 PREFLIGHT CHECK
The airplane should be given a thorough preflight and walk-around check. The preflight should include
a check of the airplane’s operational status, computation of weight and C.G. Iimits, takeoff distance and
in-flight performance. A weather briefing should be obtained for the intended flight path, and any other
factors relating to a safe flight should be checked before takeoff.
CAUTION
The flap position should be noted before boarding the aircraft.
The flaps must be placed in the “UP” position before they will
lock and support weight on the step.
Upon entering the cockpit, release the seat belts securing the control wheel. Turn off all avionics equip-
ment. Turn the master switch “ON” and check the fuel quantity gauges for sufficient fuel. After the fuel
quantity check is made turn the master switch “OFF’ and check that the ignition switch is “OFF.”
To begin the exterior walk-around, check for external damage and operational interference of the
control surfaces or hinges. Insure that the wings and control surfaces are free of snow, ice, frost or any
other foreign materials.
An operational check of the stall warning system and navigation lights should now be made. Turn the
master switch “ON.” Lift the detector while checking to determine if the horn is actuated and check that
the navigation lights are illuminated. The master switch should be returned to the “OFF” position after the
checks are complete.
A visual check of the fuel tank quantity should be performed. Remove the filler cap from each tank
and visually check the supply and color. Be sure to secure the caps properly after the check is complete.
The fuel system sumps and strainer should be drained daily prior to the first flight and after refueling
to avoid the accumulation of contaminants such as water or sediment. Each fuel tank is equipped with an
individual quick drain located at the lower inboard rear comer of the tank. The fuel strainer is equipped
with a quick drain located on the front lower corner of the firewall. Each of the fuel tank sumps should be
drained first. Then the fuel strainer should be drained twice, once with the fuel selector valve on each tank.
Each time fuel is drained, sufficient fuel should be allowed to flow to ensure removal of contaminants. This
fuel should be collected in a suitable container, examined for contaminants, and then discarded.
CAUTION
When draining any amount of fuel, care should be taken to ensure
that no fire hazard exists before starting the engine.
After draining, each quick drain should be checked to make sure it
has closed completely and is not leaking.
