The incident was reported around 7.40 p.m. Thursday, when a SpiceJet Boeing 737-800, operating on Delhi-Hyderabad route (SG 239), was going to take off from the runway.
"Preliminary observations suggest that the aircraft came off the taxiway guiding line and as a result, it hit the post," said a spokesperson of the IGI airport operator.
All the passengers on board were safe, official said.
Following the incident, the pilot of the aircraft aborted take-off and the passengers were sent to Hyderabad in a separate plane after a delay of about two hours.
During the incident, 137 passengers, two pilots and 4 cabin crew members were inside the plane.
