Royal Navy (765 Naval Air Squadron) — Flight HE274

A Vickers Wellington bomber crashed into a residential area in Rabat, Malta, during a fighter affiliation training exercise, killing all four crew members and 16 civilians on the ground for a total of 20 fatalities. The aircraft was performing evasive maneuvers against a Supermarine Spitfire when it entered a port turn and descended at a 20 degree angle until impact. A magisterial inquiry suggested that a hydraulic fluid leak may have released toxic fumes, incapacitating the crew and leaving them unable to control the aircraft or transmit a distress call.

Report

Investigation Summary

The accident involved the last Vickers Wellington in service with the Fleet Air Arm. On the morning of the crash, the crew conducted a pre-flight inspection and declared the aircraft airworthy for a training exercise with a Spitfire from No. 73 Squadron RAF. The exercise involved the Spitfire performing dummy attacks while the Wellington practiced evasive maneuvers. After three successful passes, the Spitfire began a fourth attack from below. At an altitude of approximately 4,000 to 5,000 feet, the Wellington suddenly turned to port and began a steady descent. It struck a row of houses in St. Publius Street, Rabat, and exploded. The resulting fire and structural collapses destroyed 18 houses and left 72 families homeless. Rescue efforts were complicated by unstable masonry and the spread of fire, requiring the use of naval generators to continue work through the night.

Final Conclusions

The magisterial inquiry led by Magistrate Albert Camilleri concluded that while the exact cause could not be determined with absolute certainty, the most probable cause was the leakage of hydraulic fluid. This leak likely released toxic fumes into the cockpit, incapacitating the crew and rendering them unable to maintain control or transmit a distress signal. The inquiry found no evidence of an in-flight fire, despite some witness reports of smoke, and noted that the aircraft had been declared airworthy by the crew just prior to the flight.
