Browne, who reached Gauchar in Uttarakhand Wednesday morning to boost the morale of IAF personnel, said, "All the 20 bodies have been recovered and the cockpit voice recorder of the aircraft has also been found."
The Air Chief Marshal will also do an aerial survey of the chopper crash site.
"We will be able to ascertain the reason of the crash only after analysing the cockpit voice recorder that has been recovered," he added.
Browne also said that the rescue operations would be wrapped up within two-three days after the weather clears up.
The air chief marshal also offered condolence on the death of the personnel belonging to IAF, Indo-Tibetan Border Police (ITBP) and National Disaster Response Force (NDRF) who died in the Mi-17 V5 helicopter crash.
The crash claimed the lives of nine personnel of NDRF, six of the ITBP and five of the Indian Air Force.
