Runway Incident Involving RJ 85 and Cessna C 501 at LKPR

Event Overview On 9 March 2005, the Czech technical investigation institute ÚZPLN reported an incident at LKPR involving two aircraft: an RJ 85 operated by Estail, registration DAT67N, and a Cessna C 501 operated by Goldeck-Flug, registration GDK109. Both aircraft were on runways 24 and 31, respectively, at 11:26 UTC. ## Sequence of Events Radio communications on 118.1 MHz showed that GDK109 was cleared to enter runway 31 and hold, while DAT67N was cleared to enter runway 24 and hold. At 11:26:24, tower issued a takeoff clearance to GDK109 from runway 31. At 11:26:34, DAT67N acknowledged that clearance and began its takeoff roll on runway 24. GDK109 then requested confirmation of its own takeoff clearance. The tower confirmed the clearance for GDK109, and the aircraft continued its takeoff. At 11:27:12, the tower instructed DAT67N to hold position, abort the takeoff, and stop immediately. DAT67N acknowledged and aborted its takeoff. After braking, the tower instructed DAT67N to exit runway 24 via taxiway B. ## Findings The investigation found that both aircraft began takeoff rolls simultaneously on runways 24 and 31. The crew of DAT67N acknowledged a takeoff clearance intended for GDK109 and began its takeoff. The tower did not immediately react to this error. After GDK109 requested confirmation of its clearance, the tower reissued the instruction for GDK109 to take off and then instructed DAT67N to abort. ## Outcome No injuries, fatalities, or aircraft damage were reported. The investigation concluded that the incident was caused by the DAT67N crew's incorrect response to a takeoff clearance intended for another aircraft and the tower's delayed reaction to the situation.
