3-30 WHEN YOU LIFT THE DAMAGED AIRPLANE 3-30-1 General
1.
Because each incident is different, you must make an analysis of your special conditions. You can use jacks, pneumatic bags, cranes or slings to lift the damaged airplane.
2.
Use caution when you use pneumatic bags. The initial (balloon-type) pneumatic bags are not stable but the newer design pneumatic bags with internal drop threads are more stable. A procedure that uses axle jacks (and cribbing) to lift the airplane in small increments can be considered as an alternative. If it is necessary to lift the fuselage, the use of cranes and slings (if available) is normally the preferred method to lift the fuselage.
