Bengaluru, May 11 (PTI) : A mid-air hydraulic leakage forced a Patna-bound IndiGo flight with 154 passengers and six crew members onboard to return to Bengaluru airport after being airborne for over 50 minutes.

The flight 6E-637 took off from the Kempegowdga International Airport in Bengaluru at 1207 hours but landed back safely at around 1300 hours this afternoon.

Confirming the return of its flight due to the hydraulic leakage, an IndiGo spokesperson in New Delhi said that the commander of the aircraft followed all standard operating procedures required for such a situation.

IndiGo confirms that 6E-637 flight enroute from Bengaluru to Patna had returned to the airport due to technical reasons, the airline said.

"While the flight was airborne, the Captain-in-Command noticed a leakage in the hydraulic line - as a precautionary measure, Captain immediately asked the Air Traffic Control (ATC) for priority landing," the spokesperson said.

The snag-hit aircraft landed back at the Bengaluru airport at 1257 hours, it said adding all passengers later left for their destination in another aircraft.
