Avro York G-ANSY took off from Malta-Luqa Airport at 12:21 for a flight to London Stansted. Shortly after becoming airborne the boost enrichment capsule in the carburetor of the no. 1 engine failed, causing a fire in the engine. It is presumed that the engine stopped producing power after 30 seconds of flight. The propeller was not feathered as the aircraft slowly climbed to 700-800 feet amsl (300-400 feet agl) with a ‘crabbing’ or ‘yawing’ motion to the left. Shortly after retracting the flaps, while still in a nose up attitude at very low flying speed, the aircraft stalled and dove to the ground near the town of Zurrieq. PROBABLE CAUSE: “The failure of no. 1 engine. However, failure alone did not cause the accident which was caused by loss of speed and consequent loss of control through an error of judgement of the pilot.”
