PREFLIGHT INSPECTION (Continued)
Outside storage for long periods may result in dust and dirt
accumulation on the induction air filter, obstructions in airspeed system
lines, water contaminants in fuel tanks, and insect/bird/rodent nests in
any opening. If any water is detected in the fuel system, the fuel tank
sump quick drain valves, fuel return line quick drain valve, and fuel
strainer quick drain valve should all be thoroughly drained again. The
wings should then be gently rocked and the tail lowered to the ground
to move any further contaminants to the sampling points. Repeated
samples should then be taken at all quick drain points until all
contamination has been removed. If, after repeated sampling, evidence
of contamination still exists, the fuel tanks should be completely drained
and the fuel system cleaned.
If the airplane has been stored outside in windy or gusty areas, or tied
down adjacent to taxiing airplanes, special attention should be paid to
control surface stops, hinges, and brackets to detect the presence of
potential wind damage.
If the airplane has been operated from muddy fields or in snow or slush,
check the main and nose gear wheel fairings for obstructions and
cleanliness. Operation from a gravel or cinder field will require extra
attention to propeller tips and abrasion on leading edges of the
horizontal tail. Stone damage to the propeller can seriously reduce the
fatigue life of the blades.
Airplanes that are operated from rough fields, especially at high
altitudes, are subjected to abnormal landing gear abuse. Frequently
check all components of the landing gear, shock strut, tires, and
brakes. If the shock strut is insufficiently extended, undue landing and
taxi loads will be subjected to the airplane structure.
To prevent loss of fuel in flight, make sure the fuel tank filler caps are
tightly sealed after any fuel system check or servicing. Fuel system
vents should also be inspected for obstructions, ice or water, especially
after exposure to cold, wet weather.
Prior to flight, verify there is an adequate oxygen supply for the trip
intended, by noting the oxygen pressure gage reading, and referring to
Section 7, Figure 7-10, Oxygen Duration Chart. Also check that the
face masks and hoses are readily accessible and in good working
condition.
