Piper Warrior III Maintenance Manual page 103

Jacking the airplane is necessary to service the landing gear and other operations. The jacking operation
is normally performed using tripod jacks. In other situations (i.e. - emergency, post-accident lifting, etc.),
slings or air bags may be more appropriate.
If wing or fuselage shoring is required, make sure the support is contoured to conform to the surface it is
supporting.
Jacking
A. Align jacks under the wing respective pads on the wing front spar.
CAUTION: BE SURE TO APPLY SUFFICIENT TAIL SUPPORT BALLAST. OTHERWISE, THE
AIRPLANE WILL SLIP FORWARD AND FALL ON THE FUSELAGE NOSE SECTION.
B. Attach a tail stand with approximately 250 pounds ballast to tail skid.
C. Carefully raise jacks until all three wheels are clear of the surface.
