SECTION 8
HAND/SERV/MAINT
8.17 LANDING GEAR SERVICE (CONTINUED)
In jacking the aircraft for landing gear or other service, two hydraulic
jacks and a tail stand should be used. At least 400 pounds of ballast should be
placed on the base of the tail stand before the airplane is jacked up. The
hydraulic jacks should be placed under the jack points on the bottom of the
wing and the airplane jacked up until the tail skid is at the right height to
attach the tail stand. After the tail stand is attached and the ballast added,
jacking may be continued until the airplane is at the height desired.
The steering rods from the rudder pedals to the transverse bellcrank in
the nose wheel tunnel are factory adjusted and should be readjusted only in
accordance with the applicable rigging specification. Nose wheel alignment
is accomplished by adjusting the rod end(s) on the steering bungee assembly
in such a way that the nose wheel is in line with the fore and aft axis of the
plane when the rudder pedals are centered. Alignment of the nose wheel can
be checked by pushing the airplane back and forth with the rudder two
degrees to the right to determine that the plane follows a straight line. The
turning arc of the nose wheel is 30 +/- 1 in either direction and is limited by
stops at the trunnion forging or the forward steering contact arm mounted
on the engine mount.
The rudder is set to 2 right with the rudder
pedals neutralized and the nose wheel centered.
8.19 PROPELLER SERVICE
The spinner and backing plate should be cleaned and inspected for
cracks frequently. Before each flight the propeller should be inspected for
nicks, scratches, and corrosion. Significant damage must be repaired by a
qualified mechanic prior to flight. Nicks or scratches cause an area of
increased stress which can lead to serious cracks or the loss of a propeller
tip. The back face of the blades should be painted when necessary with flat
black paint to retard glare. To prevent corrosion, the surface should be
cleaned and waxed periodically.
