Narrative:
Jet Airways flight 2374, a Boeing 737-85R (WL), suffered a runway excursion at Goa-Dabolim Airport (GOI) in India.
The flight crew requested ATC for a pushback clearance at 04:52 local time. ATC cleared the flight to line up on runway 26 by entering Taxiway N1 and backtracking. The crew requested for an intersection departure, but this was not allowed by ATC. The starboard engine was started followed by start of port engine at 04:53.
At 05:01, as the aircraft was taxiing down th runway, ATC gave a departure clearance to the aircraft. It was cleared to Mumbai at FL220. The aircraft thereafter lined up on runway 26 after making a 180° turn at the turn pad. At 05:03, flight 2374 was cleared for take-off.
The crew completed the before take-off checklist and at 05:03 pushed the thrust levers to increase the thrust. After the Throttle Lever Angle (TLA) had passed 40%, the pilot in command pressed the TOGA button for takeoff.
As soon as TOGA was pressed, the aircraft started drifting towards the right. Within 10 to 12 seconds the aircraft went off the runway, onto the grass. The crew tried to apply brakes, rudder and use nosewheel steering to steer the aircraft. Due to heavy bumps they could not apply control effectively.
The aircraft stopped at a distance of 219 m from the runway edge and just short of perimeter road. In the process it had hit PAPI lights. The engine had hit a vertical pillar of 2.3 m in height, located at 92 m abeam the center line of runway 26. The pillar also damaged the left bottom portion of the fuselage.
The aircraft was evacuated after coming to rest. Sixteen passengers suffered minor injuries during the evacuation.

Probable cause of the Accident: "The PIC pressed TOGA when the thrust on no.1 engine was 40% and no.2 engine was 28% in deviation from SOP, which caused the No.1 engine thrust to increase at a faster rate than no.2 resulting in aircraft yawing towards right. In the absence of timely desired corrective actions including reject takeoff, the aircraft veered off the runway and continued to move in a semicircular arc on the undulated ground resulting in substantial damages to the aircraft."
