According to Zaidi, the commander of the plane had reported about bad weather before the crash.
"The investigation will be done independently. The investigation will not be carried out by the DGCA. The Government will appoint a committee of inquiry. A working group will be set up to review existing safety norms," Zaidi said.
The investigation will be the first of its kind in India. The matter to be probed into is as what went wrong with the P-12 turboprop aircraft, which belongs to Delhi-based Air Chartered Services India Pvt Limited.
The plane did not have a cock pit voice recorder or even a data recorder, said sources. Both essential as it could lead to what went wrong in the aircraft.
The final conversation between the pilot and the Air Traffic Controller (ATC) will also be looked into. The broken parts of the plane and the propeller will provide the investigators with clue on whether the engine of the plane was functioning properly.
Eyewitnesses claim that the aircraft flipped and went into a downward spiral, making it difficult for the pilot to handle the plane.
Questions are being raised on why the aircraft was allowed to take off from Patna to Delhi, when bad weather was reported from Delhi.
The aircraft was hired by Apollo Hospital, Delhi to take 20-year-old Rahul, for treatment in Delhi who was in coma and suffering from jaundice.
The aircraft crashed on Wednesday, May 25, in Faridabad, killing all the seven on board and three on the ground.
