meteorological conditions, check the pitot static source and stall warning
heaters (if equipped) for proper heating within 30 seconds of activating the
proper switches.
5. Following the accomplishment of major maintenance procedures on the
airplane, the preight inspections should be modied to give extra attention
to the ight controls and trim tabs to ensure freedom of movement and
actuation in the correct direction. Also, all inspection panels on the airplane
should be checked to ensure proper security of installation.
6. If the airplane has been exposed to ground handling, especially in a
crowded hangar, it should be checked carefully for dents and scratches on
the wings, fuselage, propeller, ight controls and empennage. Also check
for damage to navigation lights, strobe lights and antennas. If the airplane
has been parked outside in high wind conditions or exposed to propeller/jet
wash, carefully inspect the ight control surface stops, hinges and brackets
for signs of wind damage.
7. If the airplane has been operated on an unimproved runway/taxiway, check
the propeller blade tips and the leading edges of the propeller blades and
horizontal tail for abrasions. Airplanes operated in and out of unimproved
strips, especially at high altitudes, are subjected to high loads on the
landing gear. Accomplish frequent inspections of the landing gear, tires
and brakes.
8. Outside storage may result in water accumulation in the pitot/static system
and fuel tanks. Dust and dirt can also enter the engine air inlet and exhaust
areas. If any water is expected in the static line, open the static source
drain valve and drain completely. Ensure the static source drain valve is
returned to the closed position prior to ight.
9. If any water is found to be present in the fuel system, the inboard fuel tank
sump quick drain valves, fuel reservoir quick drain valve and the rewall
fuel lter quick drain valve should all be thoroughly drained and checked
until there is no further sign of water or debris contamination in the fuel
system.
10. Prolonged storage of the aircraft may result in considerable water buildup
in the fuel system due to water separating from fuel additives. This is
indicated by excessive amounts of water accumulating in the fuel tank
sumps. Refer to “Section 8” of this manual and “Chapter 12” of the
KODIAK 100 Airplane Maintenance Manual for fuel system servicing
procedures.
11. To prevent inadvertent loss of fuel in ight, ensure the fuel tank ller caps
are tightly sealed following visual checks of the fuel quantity or servicing.
The fuel system vents should be inspected for obstructions, ice or water,
especially following ights into cold weather.
12. The interior inspection will vary according to the type of ight plan and
the optional equipment installations. Prior to ights at high altitudes, it is
important to check the oxygen supply equipment for proper operation and
availability of face masks and hose assemblies.
