What happened
During a nighttime approach to Belfast-Nutt's Corner under marginal weather conditions, the crew began their descent toward the airfield. While on final approach, the aircraft, known as 'Lord Saint Vincent', descended below the intended glide path. The plane struck the top of the sixth approach light, which sat 113 feet below the required altitude, before appearing to level off.
The aircraft made contact with the ground approximately 250 feet ahead of the initial impact point and slid along the surface for roughly 82 feet. Following this, the plane rose briefly and collided with an SBA van. The sequence continued as the aircraft struck the ILS building, eventually breaking apart approximately 200 yards before reaching the threshold of runway 28. The accident resulted in 27 fatalities, including three crew members, while eight individuals sustained injuries. The airframe was completely destroyed during the impact.
Findings
An official inquiry into the crash determined that there were no signs of mechanical malfunction and confirmed that all aircraft documentation was correct. Furthermore, the crew members were found to be properly qualified and had followed standard control procedures. The investigation concluded that the pilot encountered environmental conditions that were deceptive in nature. Ultimately, the primary cause was identified as an error of judgment by the Captain.
