1.  General
A.  Two general types of airplane lifting will be covered in this chapter, airplane jacking for normal maintenance, and lifting damaged airplanes.
B.  When the airplane is jacked for normal maintenance, the main and auxiliary jacking points are used. The airplane is usually jacked for weighing, leveling, alignment checks, and gear retraction.
C.  Procedures for lifting and recovery of damaged aircraft are contained in the Boeing Document D6-40146, 707, 727, 737 AIRPLANE RECOVERY.
D.  When necessary to obtain additional tail clearance for positioning an airplane in a hangar or storage area, a nose lift dolly may be used to tilt the airplane. The nose lift dolly raises the airplane nose section, causing the airplane to rotate about the main gear.

LIFTING AIRPLANE FOR MAINTENANCE
1.  General
A.  Lifting the airplane for maintenance is accomplished by using conventional airplane jacks at jacking points provided on the wing, forward and aft body or at the nose and main landing gear. The jacking points on the wing and body are provided with receptacles for the attachment of removable ball-type jack adapters. The nose and main landing gear jacking points are integral with the landing gear.

JACK AIRPLANE
1. General
A.  The airplane is provided with three main jacking points and four auxiliary jacking points. The main jacking points are wing jacking point D and aft body jacking point G. The four auxiliary jacking points consist of one stabilizing and three landing gear jacking points. The stabilizing jacking point is forward body jacking point C. The three landing gear jacking points are points E-F at each main gear axle and points A-B under the nose gear axle. See Fig. 201 and 202 for jacking point locations, jacking point maximum loads, wing and body jack adapters and applicable jacks.
