4-30-4 Other Support Systems When You Cannot Use the Landing Gear
1. Movable Cranes
A. When a landing gear is not a possible solution for you, a movable crane is your fastest solution. But you must have a ground surface with a sufficient strength. The other related conditions must also be sufficient. Then you can lift the wing and move the crane and the airplane together to a repair area.
B. There are many different solutions that use a movable crane. See CHAPTER 3 for more data on solutions that use movable cranes and slings.
2. Trucks (Low-Bed Trailers) or Dollies
A. You can use trucks (low-bed trailers), dollies or other movable equipment to give support to a wing or the fuselage. Make sure you have a ground surface with sufficient strength for the wheels of the equipment (see SECTION 2-10 and SECTION 4-10).
B. Use pads to prevent damage to the airplane surfaces. The pads can be foam, rubber (tires), pneumatic bags or other soft materials (mattresses) that give good protection. Make sure that the pad positions stay stable while you move the airplane. Foam and rubber pads (tires) are good because they have a good friction (coefficient of friction) on the airplane surfaces. Make sure that your pads always align with the contour of the airplane surfaces and there are no point loads. This keeps a constant pressure on all airplane surfaces that is less than the recommended maximum pressures of the manufacturer.
C. You can fill the support areas with some foam when you use trucks or other commercial transportation equipment. You can use rubber supports (tires) to hold a wing or the fuselage (see the rubber tires in Figure 4-28). You can use wood beams to align the rubber supports (tires) to the dihedral of the wing. You can use special airplane tools (part numbers to be determined) to hold the fuselage on the movable equipment. You can also use wood supports (cribbing) on the movable equipment to hold landing gears that are not fully folded.
3. Commercial Transportation Equipment
A. Possibly, you can use the commercial equipment and procedures for the transportation of large structures. The structures can be transformers or other large items (houses, boilers or buildings). Examine these possible solutions if a usual airplane procedure is not easy for you.
