PIPER AIRCRAFT CORPORATION SECTION 8
PA-28-181, ARCHER If HANDLING, SERV & MAINT
In jacking the aircraft for landing gear or other service, two hydraulic
jacks and a tail stand should be used. At least 250 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 arms from the rudder pedals to the nose wheel are adjusted
at the nose wheel by turning the threaded rod end bearings in or out.
Adjustment is normally accomplished at the forward end of the rods and
should be done in such a way that the nose wheel is in line with the fore and
aft axis of the plane when the rudder pedals and rudder are centered.
Alignment of the nose wheel can be checked by pushing the airplane back
and forth with the rudder centered to determine that the plane follows a
perfectly straight line. The turning arc of the nose wheel is 30.0° + 2° ineither
direction and is limited by stops on the bottom of the forging.
The rudder pedal arm stops should be carefully adjusted so that the
pedal arms contact the stops just after the rudder hits its stops. This
guarantees that the rudder will be allowed to move through its full travel.
8.17 PROPELLER SERVICE
The spinner and backing plate should be © frequently cleaned and
inspected for cracks. Before each flight the propeller should be inspected for
nicks, scratches, and corrosion. If found, they should be repaired as soon as
possible by a rated mechanic, since a nick or scratch causes 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.
