The commander of an Alliance Air Mumbai-Hyderabad-Vizag flight number CD 7561 decided to "reject" take off while on the tarmac at the Mumbai airport on Saturday morning following a technical snag detected in the aircraft.
Airline officials said the aircraft's speed indicator failed at the last minute and under the DGCA rules, the pilot of such an aircraft cannot carry on with the flight.
The aircraft had 115 passengers and six crew members on board and was headed for take off when the pilot decided to abort the take-off.
The plane was brought back to the tarmac and all the passengers disembarked.
Alliance Air is a subsidiary of Indian (Airlines) and connects to non-metro routes.
Confirming the incident Indian (Airlines) spokesperson from Mumbai said, "The pilot decided not to take off due to technical snag. The plane is now grounded and is currently under repair."
Forty-one passengers, who were booked for Hyderabad, were accommodated in Indian (Airlines) schedule flight number IC 617 (for Hyderabad) which left at 10.15 am. The remaining 64 passengers, who were booked for Vizag, were accommodated in a special Indian (Airlines) aircraft which left for that destination at 12.25 pm.
"All the passengers have now reached their destinations," said the spokesperson.
In the morning, the Alliance Air flight was originally scheduled to depart at 8 am. The aircraft was then pushed back (after the closure of the door of the aircraft, the plane pushes back to get into the runway) at 8.05 am and was on the taxi way to take off.
When it got the go-ahead from Air Traffic Control (ATC) for take off, it moved on to the runway, but aborted take off at the last moment.
From the tip-end of the runway it returned to the tarmac at 8.40 am.
