The accident was notified to the Deputy Director Accident Investigation Bureau at his official residence and an accident inspector was dispatched to the scene immediately.
The accident occurred on the take off run on the runway 19L, when the aircraft was accelerated to about 100 knots and it suddenly started to veer off the runway centre line. A maximum left rudder pedal application could not correct the runway side over-run onto the right hand shoulder.
The side over-run continued until the aircraft ran into an undulating terrain surface of the shoulder which sheared off the nose gear and the airframe fuselage impacted with the ground with an immense momentum which distorted the front section airframe.
The report concludes that what was merely runway side over-run resulted into an accident exacerbated by an improperly maintained runway shoulder
