LEVELING AND RIGGING
Leve ling the Aztec for purposes of reweighing or rigging is
accomplished as follows:
1. Partially withdraw the two machine screws located on
the side of the fuselage just forward of the right stabilator. These
screws are leveling points, and the airplane is longitudinally
Jevel when indicated by the leveling instrument placed on the
screws.
2. Put the airplane on jacks to obtain the longitudinally
Jevel position.
3. To Jevel the airplane laterally and with the airplane on
jacks, place a bubble-protractor on a straight edge held along
the front spar on the under surface of the wing. Obtain an indi-
catioo of five degrees dihedral on the protractor by lowering or
raising the wing by the use of the jacks. After checking the first
wing at five degrees dihedral, the opposite wing should be
checked to make sure it has equal dihedral.
