ABLE
STORAGE.
Aircraft
placed in non-operational storage for a
m~imum
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 revolu-
tions. This action
"limbers"
the oil and prevents any accumulation of
cor-
rosion
on
engine cylinder walls.
·

For
maximum safety, check that the ignition switch
is
OFF, the throttle
is
closed, the mixture control .is in
the idle cut-off position, and the airplane
is
secured
before rotating
the
propeller
by
hand.
Do
not stand

arc
of
the propeller blades while turning
the propeller.

INSPECTION REQUIREMENTS.
As required
by
Federal Aviation Regulations, all civil
aircraft
of
U.
s.
registry must undergo a complete inspection (annual) each twelve calendar
months.
In
addition
to
the required
ANNUAL
inspection,
aircraft
operated
commercially (for hire) must have a complete inspection every
100
hours
of
. operation. · ·
In
lieu of the above requirements, an
aircraft
may be inspected in
accordance with a progressive inspection schedule, which allows the work
load
to
be
divided into smaller operations that can be accomplished in
shorter time periods.
