Cessna 1973 172 - Inspection Service and Inspection Periods

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 acciunulation of cor-
rosion on engine cylinder walls.
IMPORTANT
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
within the arc of the propeller blades while turning
the propeller.
After 30 days, the aircraft should be flown for 30 minutes or a groimd
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 rimup also helps to eliminate excessive accumulations of water
in the fuel system and other air spaces in the engine. Keep fuel tanks full
to minimize condensation in the tanks. Keep the battery fully charged to
prevent the electrolyte from freezing in cold weather. If the aircraft is to
be stored temporarily, or indefinitely, refer to the Service Manual for
proper storage procedures.
INSPECTION SERVICE AND INSPECTION PERIODS.
With your airplane you will receive a Customer Care Program book.
Coupons attached to the Program book entitle you to an initial inspection
and the first 100-hour inspection at no charge. If you take delivery from
your Dealer, he will perform the initial inspection before delivery of the
airplane to you. If you pick up the airplane at the factory, plan to take it
to your Dealer reasonably soon after you take delivery on it. This will
permit him to check it over and to make any minor adjustments that may
appear necessary. Also, plan an inspection by your Dealer at 100 hours
or 180 days, whichever comes first. This inspection also is performed
by your Dealer for you at no charge. While these important inspections
will be performed for you by any Cessna Dealer, in most cases you will
prefer to have the Dealer from whom you purchased the airplane accom-
plish this work.
