Leveling Airplane - Piper PA-44-180 SEMINOLE Maintenance Manual

LEVELING.
All configurations of the airplane are provided with a means for longitudinal and lateral leveling. The
airplane may be leveled while on jacks, during the weighing procedure while the wheels are on the ground. To
level the airplane for purposes of weighing or rigging, the following procedures may be used:
1. To longitudinally level the airplane, partially withdraw the two leveling screws located immediately
below the left front side window. (Refer to Figure 8-1). Place a spirit level on these screw heads and
deflate the nose wheel tire or adjust the jacks until the bubble of the level is centered.
2. To laterally level the airplane, place a spirit level across the main spar box (Refer to Figure 8-1) and
deflate the tire on the high side of the airplane or adjust either jack until the bubble of the level is
centered.
