A Dubai-bound Air Express flight from Mumbai carrying 186 persons on board landed back in the city under emergency conditions on Sunday after being in air for over an hour due to a "hydraulic" failure, a source said.
"There was no harm to any passenger. The Boeing 737-800 plane landed safely at Chhatrapati Shivaji Maharaj International Airport," he said.
"Full emergency was declared at 14.28 am for Air India Express flight AI 247 operating on the Mumbai-Dubai route following the pilot seeking a diversion back to the city due to hydraulic failure," said the source.
An Air India Express spokesperson said that a "technical glitch" forced the aircraft to turn back to Mumbai.
"Due to the technical glitch.... noticed by the pilot-in-command, the flight crew decided to turn back the aircraft to Mumbai in view of passengers' safety," the spokesperson said.
He said there were 177 passengers and six crew on board.
The aircraft arrived back safely at around 3 pm, he added. The Boeing 737 plane had departed from Mumbai around 2 pm.
"The snag was later rectified by airline engineers and aircraft was declared airworthy. The same plane with all 177 passengers resumed its journey at around 8 pm," the spokesperson said.
