The Cessna 680 was executing an RNAV approach to runway 04 of Bourgas Airport (BOJ), Bulgaria. At approx. 10:34 UTC during the rollout a few seconds after the touchdown, the aircraft veered to the right from the centerline, left the runway near the C taxiway, hit a concrete block with aeronautical equipment and stopped on the ground between the apron and the runway.
The flight crewmembers were not injured, but the aircraft received damages on the left nose part of the fuselage and the left brace strut of the nose gear was broken.
