Meanwhile, Indian authorities are also probing the accident.

The official said the government was eager to come out with findings of the probe to send out a signal of India's preparedness to upgrade its aviation sector according to guidelines of the International Civil Aviation Organisation.

This was a critical condition laid down by US FAA. It had said if India failed to do so, the US would curtail flights from India and impose more stringent security checks.

Pawan Hans Corporation chairman and managing director R.K. Tyagi, who heads a five-member high-powered committee of Directorate General of Civil Aviation (DGCA) probing the crash, said it would come out with its findings in three-four days.
