Narrative:The undercarriage wouldn't lock up after takeoff, so the crew recycled the gear a couple of times. On the third attempt, the bogie (which was not rotating in the right sequence) fouled the main hydraulic jack fracturing the attachment bolt of the shuttle valve for the main and emergency 'down' hydraulic lines. All hydraulic fluid escaped and the gear couldn't be extended anymore. An emergency landing was carried out on a foamed runway at Manston.
PROBABLE CAUSE: "The undercarriage failed to lock down due to loss of the hydraulic fluid from the main and emergency systems. This resulted from fracture of the hydraulic lines consequent upon fouling of the port undercarriage retraction jack head by the bogie through incorrect setting up of the retraction sequence valve."
