Review DOUGLAS Aircraft Helical Torsion Spring New fits DC3

The Douglas DC-3 helical torsion spring, model number 1117985, is a critical component in the landing gear system of this iconic aircraft. This spring, manufactured by Douglas Aircraft Company, is designed to provide the necessary torque to hold the wheels in place during takeoff and landing, ensuring a stable and safe aircraft operation.

The helical torsion spring is made from high-strength, heat-treated steel, which offers superior durability and resistance to fatigue. The spring's helical design allows it to store and release energy efficiently, making it an ideal choice for applications where torque is required. The spring has a diameter of approximately 1.25 inches (3.175 cm), with a length of around 4 inches (10.16 cm) and 11 active coils.

One end of the spring is threaded to accommodate a nut, while the other end is designed to attach to the landing gear assembly. The threaded end also features a locknut to prevent the nut from loosening during operation. The spring's pitch and coil diameter are specifically calculated to provide the required torque for the Douglas DC-3 landing gear system.

This Douglas DC-3 helical torsion spring is a vital component for any aircraft restoration or maintenance project. Its precision engineering and high-quality materials ensure optimal performance, providing peace of mind for pilots and passengers alike. The spring's availability from trusted aviation suppliers allows aviation enthusiasts and professionals to maintain the historical significance and safety of their Douglas DC-3 aircraft.
