He said only after the Directorate General of Civil Aviation (DGCA) investigation concludes, the reason for the crash could be known.
"The CVR has been retrieved from the crash site and it has been sent for investigation," he said.
The DG maintained that the Superking B-200 aircraft was "technically perfect" when it took to air yesterday even as he fully empathised with the anger and grief expressed by the family members of the ten killed personnel who have accused the government and the paramilitary of using "old" aircraft.
"I would emphatically say again that there should be no doubt in anybody's mind about this aircraft which was not a very old," he said.

The DG said the plane was "under-exploited" as it had flown about just 4,700 hours in the last 20 years.
Pathak said the plane was inducted in 1995 and it had over 2,700 landings with the air wing of the country's largest border guarding force.
