Narrative:SAS flight SK2746, a Bombardier CRJ-900, was parked at aircraft stand A17 at Copenhagen's Kastrup Airport in Denmark. Passengers were boarding the aircraft and ground handling personnel loaded baggage and cargo. At the same time a tractor driver had to move an x-ray trailer from the eastern to the western part of the airport.
When the tractor driver arrived at the garage, he inspected the trailer hitch, the hitch pin and the availability of the locking ring. The inspection did not give rise to remarks.
A similar equipped tractor stood next to the tractor intended for use. The tractor driver observed that the gears of the tractor were not working properly, when the tractor moved forward, and he decided to replace the defective tractor with the tractor standing next to the tractor intended for use.
Due to lack of space, the tractor driver did not inspect the trailer hitch, the hitch pin and the availability of the locking ring of the other tractor. The tractor driver attached the x-ray trailer to the tractor. The tractor driver did not install the safety wire for the x-ray trailer braking system.
When driving on the airport southern service road with a speed of approximately 40 kilometres per hour and passing abeam aircraft stand A14, the tractor driver noticed a bump on the road. The tractor driver checked his rear-view mirror but did not observe anything unusual and continued driving. Suddenly, the tractor driver heard a loud bang and observed that the x-ray trailer had detached from the tractor and had collided with the aircraft at aircraft stand A17.
The trailer impacted the right hand rear fuselage below the no.2 engine, causing a large hole.
Probable Cause:CONCLUSIONS: "Non-compliance with the Danish road traffic act led to an x-ray trailer detachment from a tractor on the aerodrome southern service road at EKCH. The x-ray trailer detachment caused substantial damages to OY-KFF parked at aircraft stand A17."
