What happened
On October 8, 2001, a collision occurred at Milano Linate airport involving a Boeing MD-87, registration SE-DMA, and a Cessna 525-A, registration D-IEVX. Following the impact between the two aircraft, the Boeing MD-87 struck a baggage building, leading to a significant fire and extensive damage to the aircraft and airport infrastructure.
The investigation
The investigation by the Italian authorities examined the movement of both aircraft on the ground, the air traffic control environment, and the airport's physical infrastructure. Investigators analyzed the taxiway markings, including unofficial markings on the west apron, and evaluated the effectiveness of the airport's low visibility procedures. The study also reviewed the communication between the tower and ground services, as well as the adequacy of the airport's emergency response capabilities and the visibility of ground aids during the event.
Findings
Key factors contributing to the accident included inadequate ground markings and signage on the airport maneuver area, specifically regarding unofficial markings at the west apron. The investigation also identified issues with the visibility of ground aids and the coordination of emergency services. Furthermore, the investigation noted that the effectiveness of the airport's low visibility procedures and the clarity of instructions provided to pilots were critical elements in the sequence of events leading to the collision.
