The Czech CAAII released their final report concluding the cause of the serious incident was:

Failure of the human factor. Failure to follow the procedure specified by the ATS by the A319 crew.

The CAAII analysed that the crew was in possession of an approach chart which conformed to Czech's AIP and included the instruction: "Unless otherwise instructed, after ERASU continue on heading 062°, radar vectoring will be provided." The crew however did not comply with that instruction but turned to maneouvre to align with runway 24 without instruction by air traffic control. The controller caught the turn and instructed the turn left heading 060 when the aircraft were 4.1nm apart, the crew acknowledged and advised they were following the standard procedure, due to the slow response by the crew to controller repeated to turn left heading 060, the aircraft were then 3.0nm apart, in addition the controller instructed to climb to FL060.

The CAAII pointed out several confusions within the crew testimony, for example the crew referenced waypoints of the ILS approach chart runway 24 while talking about the standard arrival route (STAR LOMKI 4S), where those waypoints were not listed. The crew also named the arrival route LOMKI 4S SID (standard instrument departure) and a confusion over the Instrument Approach Fix. The crew reported that the separation between the aircraft never went below 3nm when radar data showed a minimum lateral separation of 1.7nm.

The CAAII analyzed: "Pursuant to the Regulation L13, Attachment C, this incident has been qualified as a serious incident “Near collision requiring a collision avoidance manoeuvre to avoid a collision”."
