4-10 WHEN YOU MOVE AN AIRPLANE THAT IS NOT DAMAGED TO A RUNWAY 4-10-1 General
1.
You can have an airplane that moves off the runway and stops with its wheels below some soft surface material. In this condition, it is possible that there is no damage to the airplane. It is also possible that you cannot try a usual procedure to tow the airplane to the runway.
2.
If only one main gear is off the runway, move all the fuel from that side of the airplane. Move the fuel from that wing tank and the middle tank or to the opposite wing tank. See the Maintenance Manual for the applicable procedures.
3.
Decrease the airplane weight to make it as near as possible to the OEW (Operating Empty Weight). The fuel in Item 2. above can stay on the airplane.
4.
In most incidents, you must immediately move the airplane because the runway is blocked. You can have a faster recovery operation if you schedule it carefully before you start.
5.
When you schedule the operation, include the items that follow:
A. The weight to be removed
B. The condition of the terrain
C. The type of support structure that you must make
D. The direction in which you must tow the airplane
E. Available construction equipment
F. The tow power of the vehicles
6.
When you make the decisions for the operation, you must think about these conditions:
A. You can lift the airplane wing and make a road on the ground surface.
B. You can remove the necessary material below the wing and make a road to the ground surface.
C. You must examine the brakes. The brakes can lock and they can cause the airplane to move off the runway. If the brakes are defective, you must make them serviceable before you start the operation.
D. Examine the airplane structure in the area of the landing gears.
E. Make sure the wheels turn sufficiently.
F. Install downlocks on all the landing gears that are in the extended position.
G. Attach tow lines to the tow points (lugs) on the main landing gears.
H. Put the tow truck (or winch vehicle) on the runway. This gives you an added positive force (traction) for the tow operation.
