B. Aircraft Lifting

CAUTION: YOU MUST NOT LIFT THE AIRCRAFT WITH THE SAFETY STAY.

4. Procedure
Subtask 08-21-00-581-052-A

A. Leveling of the Aircraft
(1) Transverse alignment
(a) Put the spirit level on two adjacent roller tracks, in the "Y" direction.

NOTE: To install the spirit level, you can find an area easily available between the FWD frame of the FWD cargo door and the frame FR34.
If the distance between two adjacent roller tracks is more than the spirit level length, install the spirit level on a straight RULER - STEEL of sufficient length.

(b) Operate the hydraulic jack below the wing to get the transverse alignment.
(2) Longitudinal alignment
(a) Put the spirit level on a roller track, in the "X" direction.
(b) Operate the hydraulic jack below the fuselage to get the longitudinal alignment.
(3) When you have done the longitudinal alignment, do a check of the transverse alignment.
(4) Put the safety stay in position between FR73 and FR74.
