Incident Overview
On final approach to Prague-Ruzyne Airport in limited visibility, the crew of a Tupolev TU-134 was cleared to land. Upon touchdown, the aircraft collided with a CSA Ilyushin II-18V, registered OK-NAA, which had just been cleared to line up for takeoff. The II-18 carried six crew members.
Sequence of Events
Following the collision, the TU-134 veered off the runway, lost its undercarriage, and came to rest in a snow-covered field. The II-18 sustained slight damage. All 48 occupants from both aircraft were evacuated safely, with four of them reported injured.
Investigation Findings
The official investigation determined that the air traffic controller in the tower cleared the II-18 crew to line up on the same runway where the TU-134 crew had been cleared to land seconds earlier. The separation time was insufficient. The lack of visibility was considered a contributing factor, as both crews failed to see each other.
