4-30 WHEN YOU MOVE A DAMAGED AIRPLANE 4-30-1 General
1. It is important for you to examine the folded landing gear for all possible damage. Do this during the initial airplane inspection. If this is not possible, you must do it after you lift the airplane to a sufficient height.
WARNING: YOU MUST BE VERY CAREFUL WHEN YOU MOVE THE AIRPLANE OR CHANGE ITS ATTITUDE. FUEL LEAKAGE MAY OCCUR AND CAUSE A DANGEROUS CONDITION. YOU MUST MONITOR THE AIRPLANE FOR FUEL LEAKAGE.
2. If it is possible, move the damaged airplane on its landing gears. If you use the landing gears, it can be necessary to do one of these procedures:
A. Repair the damaged gear.
B. Install a replacement gear.
C. Install some temporary gear supports to hold the weight of the airplane.
3. If you cannot use the landing gear, you must use a different system to move the airplane. It can be necessary to use one or more of these items:
A. Trucks (low-bed trailers)
B. Movable cranes
C. Transportation dollies
D. House movement equipment
E. Commercial transportation equipment
4. It is possible that you must prepare the ground surface to tow the airplane (see SECTION 2-10 and SECTION 4-10).
