ABSTRACT:
The invention is a cable restraint system for an aircraft having first and second main landing gears equally spaced from the longitudinal axis of the aircraft; the system for securing the aircraft from movement during engine run-up testing when the aircraft is positioned such that the main landing gears are in front of and the longitudinal axis thereof is aligned with a ground attachment fitting mounted to the ground. In detail, the system includes first and second coupling members. First and second cables having first and second ends, have their first ends attachable to the ground attachment fitting and the second ends attached to the first and second coupling members, respectively. A third cable is attached by its ends to the first and second coupling members. Fourth and fifth cables having first and second ends, are attached by their first ends to the first and second coupling members and attachable by their second ends main landing gears. When installed with the first ends of first and second cables attached to ground attachment fitting and the second ends of the fourth and fifth cables attached to the main landing gear, the system has a generally Y shape with the fourth and fifth cables forming the arms of the Y and the first, second and third cables forming a triangular shaped leg of the Y.
