SERVICING & INSPECTION
Standard procedure for ground handling,
servicing, inspection, airframe
maintenance, lubrication, and storage are
included in this Section. Adherence to
these procedures on a scheduled basis
can save many hours of maintenance and
aircraft down time. When a system
component requires service or
maintenance other than that outlined in
this Section, refer to the applicable Section
of this manual for complete information.
GROUND HANDLING
TOWING
Movement of the aircraft on the ground
may be accomplished as follows:
a. Pull and guide the aircraft by means of
a tow bar with the tail wheel unlocked.
b. Attach a rope harness to the main
gear when there is a need to tow the
aircraft forward through snow or over
soft and/or muddy ground.
TAXIING
Before attempting to taxi the aircraft,
maintenance personnel should be checked
out by qualified personnel. When it is
determined that the propeller area is clear,
apply the power to start the taxi roll and
perform the following:
a. Push the stick full forward to unlock
the tail wheel.
b. Taxi a few feet and check the brake
operation.
c. While taxiing, make slight turns to
determine that the tail wheel steering
is operative.
d. Avoid taxiing over ground covered with
loose stones, gravel, or other loose
material that may cause foreign object
damage to the propeller or to other
aircraft in the area.
PARKING
Head the aircraft into the wind and set the
parking brake. Do not set the parking
brake during cold wet weather because the
accumulated moisture may freeze in the
brakes. Do not set the parking brake if the
brakes are overheated. Install the internal
control lock and place the chocks under
each main wheel.
MOORING
Reference Fig. 2-1
Park aircraft as previously outlined. In
winds up to 20 knots, secure the aircraft at
the wing tie down rings. For winds above
20 knots, tie the tail and main gear as well
as the wings. Install external control
surface locks. The aircraft should be
placed in a hangar when wind velocity is
predicted to exceed 50 knots. When
mooring the aircraft, use 3/4-inch manila or
nylon rope. A clove hitch or other anti-slip
knot should be employed. If a manila rope
is used for tie down, allow enough slack to
compensate for shrinkage of the rope fiber
without damaging the aircraft.
JACKING
Reference Fig. 2-1
Jack points are provided on each main
spar and located at wing stations 120 &
193.38. When using the jack points to lift
the aircraft, all hopper loads should be
removed. (Fig. 2-1) A jack point is also
provided on the tail wheel trunnion attach
fitting on the lower left longeron.
LEVELING
Reference Fig. 2-1
The aircraft may be leveled by raising the
tail to an approximate level flight position
by supporting the tail on a stable jack or
platform. Adjust the height of the tail wheel
until the left-hand lower longeron located
under the pilot’s cockpit is level. The lower
left side panel must be removed for access
to the leveling longeron.
