AIRPLANE FLIGHT MANUAL
ORIGINAL ISSUE - 03-16-2017
Do not raise the aircraft on jacks out of doors when wind velocity is over 8 KTS.
When lowering aircraft on jacks, bleed off pressure on all jacks simultaneously and
evenly to keep aircraft level as it is lowered.
-CAUTION-
-NOTE-
Individual wheels may be raised without raising entire aircraft. Wheels not being
raised should be chocked fore and aft.
SERVICING
REFUELING
Integrally sealed tanks, in forward, inboard sections of wing (LH & RH), carry the standard fuel
quantity. With aircraft positioned on level ground, service each fuel tank after flight with 100 oc-
tane or 100LL aviation grade gasoline. The fuel tank is considered full when fuel completely cov-
ers bottom of standpipe.
The optional, fuel quantity sight indicators on top of each wing tank should be used as a refer-
ence for partial refueling only. These gauges will not indicate the tank’s total capacity above 30
gallons of fuel.

Never use aviation fuel of a lower grade than 100 octane or 100LL avgas.
-CAUTION-
Fuel samples from the sump drain of each tank should always be taken before the first flight of
the day to check for water, sediment or other contamination. It is recommended that fuel samples
be taken prior to each flight. Fuel samples taken immediately after refueling may not show water
or sediment due to mixing action of refueling process.
Allow five minutes after refueling for water and sediment to settle in tank and fuel
drain valve before taking fuel samples or draining gascolator.
-WARNING-
Tank sump drains are near each wing root, forward of the wheel wells. A small plastic cup is sup-
plied as loose equipment for obtaining fuel samples. To collect a fuel sample, insert cup actuator
prong into sump drain receptacle; push upward to open valve momentarily and drain fuel into
cup. If water is in fuel, a distinct line separating water from gasoline will be seen through transpar-
ent cup wall. Water, being heavier, will settle to bottom of cup, while colored fuel will remain on
top.
Continue taking fuel samples until all water is purged from tank.
Aircraft should be in a
level position to prevent the possibility of any contamination not being at sump drain area.
The fuel system gascolator is on the cabin floor, forward of co-pilot’s seat. To flush system and
lines leading from wing tanks to selector valve, turn selector handle to the left tank position and
pull fuel drain valve for about five seconds. Repeat procedure for right tank. Be sure fuel drain
valve is returned to closed position and drain valve is not leaking.
-NOTE-
Use recommended engine break-in procedures as published by engine
manufacturer.
FUEL ADDITIVES
Ethylene glycol monomethyl ether (EGME) or other additives are not recommended
due to potential deteriorating effects within the fuel system.
