FLYABLE
STORAGE
Airplanes
placed
in non-operationa,l storage
f or a
maximum of 30 days
or
those
which receive only
intermittent operational
use
for the
first
25
hours
are considered
in flyable storage status.
Every
seventh
day during
these
periods,
the
propeller
should be
rotated by hand
through five
revolutions. This aotion
"limbers"
the oil
and
prevents
any a,ccumulation
of corrosion on
engine cylinder walls.
WARNING
For
maximum safety,
check
that the
ignition switch
is
OFF,
the
throttle
is closed,
the mixture
control
is in
the idle
cut-off
position,
andthe
airplaneis
secured before
rotating
the
propeller
by
hand.
Do not stand
within tho
arc
of
the
propeller
blades while turning the
propeller.
After 30 days, the airplane should be flown for 30 minutes or
a
ground
runup
should
be made
just
Long enough to
produce
an
oil
temperature
within
the lower
green
arc range. Excessive
ground
runup should be
avoided.
Engine runup
also helps to
eliminate
excessive accumulations
of
water in the fuel
system
and other air spacesinthe engine.
Keopfuel
