Propeller Service - Piper WARRIOR III PA-28-161 Pilot Operating Handbook

PIPER AIRCRAFT CORPORATION
PA-28-161 WARRIOR III
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.

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.
