Destination airport:?
The DC-6 had to return to Malaga due to bad weather conditions at the destination. A hydraulic system failure then caused the crew to make an emergency landing with just the nose- and right gear extended. The aircraft ran off the left side of the runway.
The hydraulics failure was caused by an attachment securing the recovery spring cable to the lower end of the leg broke during retraction of the gear. The loose spring was caught between the hydraulic cylinder and other linkages, and the piston was pushed to one side of the cylinder, causing an escape of hydraulic fluid.
