PREFLIGHT INSPECTION
(Continued)
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.
The interior inspection will vary according to the planned flight and the
optional equipment installed. Prior to high-altitude flights, it is important
to check the condition and quantity of oxygen face masks and hose
assemblies. The oxygen supply system (if installed) should be
functionally checked to ensure that it is in working order and that an
adequate oxygen supply for the trip intended, by noting the oxygen
pressure gage reading, and referring to Section 9, Supplement 6,
Figure S6-2 or S6-3, Oxygen Duration Chart.
