Section 4 – Normal Procedures
4.1 PREFLIGHT CHECK
Preflight inspection must be conducted before the first flight of the day. The
preflight inspection is recommended prior to any flight or series of flights by one
pilot on any given day. Prior to each flight, at a minimum, fuel, oil quantity must
be checked along with a general walk around the aircraft.
1. If the aircraft has been stored outside, the engine area and other points of entry
should be checked for evidence of bird or rodent occupancy. Wiring should be
checked in such a case for possible rodent bites. All control surfaces and travel
stops should be examined for damage. When operating from gravel fields, pay
special attention to propeller leading edges. Fuel caps should be periodically
monitored for any deterioration to avoid fuel leakage in-flight or water or grime
infiltration.
2. The aircraft’s general condition should be noted during a visual inspection of the
aircraft. Inspect any signs of deterioration, distortion and any damage to the
aircraft. In cold weather, all traces of ice, snow, and frost should be removed
from the aircraft. Make sure that no ice, snow or debris is trapped between any
movable control surfaces.
3. Make sure that all instruments are in good condition and that there is no cracked
or broken glass. The Airspeed indicator should read zero and altimeter should be
checked against ramp or field elevation.
4. Do not activate the electrical system when anyone is near the propeller in order
to prevent injury that can possibly result from electrical system malfunction.
5. Pay special attention to the propeller area – make sure the ignition and master
switches are OFF before touching the propeller. Avoid touching propeller, when
possible, to prevent potential injury resulting from electrical system malfunction.
Do not push the propeller in a direction opposite from normal rotation as air may
enter the oil lines.
WARNING: DO NOT FLY THE AIRCRAFT IF YOU FIND ANY DAMAGE OR
PROBLEMS DURING A PREFLIGHT INSPECTION. ALWAYS CONSULT
AUTHORIZED PERSONNEL FOR REPAIRS.
