"I have received two preliminary reports and the commission has not found any technical fault," he told the press after meeting Romanian Defence Minister Teodor Melescanu.
Roncevic said the probe into the crash was not over.
On July 11, an MI-8 helicopter crashed a few minutes after taking off from the barracks of the 204th Vukovar Brigade, injuring 10 persons, of whom three died. The cause of the crash is being established by a 10-member military and civilian commission.
