Leveling. (Refer to Figures 2-11 and 2-12.)
2-13.
The aircraft may be leveled while on jacks or during the weighing procedure. (Refer to Paragraph 2-12
for weighing.)
NOTE: Always level the aircraft laterally first, then longitudinally.
Deflate the nose wheel tire until the level position is obtained.
a. To laterally level the aircraft, place a level over the bulkhead to which the baggage door hinge
brackets are attached or on the hat section channel of the firewall bulkhead. (Refer to Figures 2-11
or 2-12 for the particular location of the aircraft being serviced.) Should equipment or other
obstacles hinder placing the level directly on the channel, use two spacers of equal length between
the level and the channel to bring the level above any obstacles.
b. To put the aircraft on jacks, refer to Paragraph 2-11.
c. To put the aircraft into a laterally level position, raise or lower one wing by adjusting the jacks or if
the aircraft is on the ground or on scales by deflating the appropriate tire until an accurate level
reading is obtained.
NOTE: All tires should be at normal inflation pressure.
d. To longitudinally level the aircraft, partly withdraw the two leveling screws on the side of the
fuselage. Refer to Figures 2-11 or 2-12 for the leveling location on the particular aircraft being
serviced. Use a level long enough to extend across the two screw heads.
e. To put the aircraft in a longitudinally level position for weighing or rigging first block the main gear
oleo struts to their full extension and the nose gear to 2.50 inches.
