A SpiceJet technician was killed after he got stuck between the hydraulic door flaps of the main landing gear of an aircraft during maintenance at Kolkata airport early Wednesday, the airline said.

The hydraulic doors 'inadvertently' got closed leaving Rohit Pandey trapped there, the airline's statement said. The landing-gear doors of the Bombardier Q400 aircraft had to be broken to rescue Pandey but he was declared dead.

The accident happened at 1.45 am, according to an airport official. 'Pandey was doing maintenance work in the right hand main landing gear wheel well area of a Q400 aircraft which was parked in Bay No 32 at Kolkata airport on July 10. Inadvertently, the main landing gear hydraulic door closed and he got stuck in between the hydraulic door flaps,' SpiceJet said.

A complaint of 'unnatural death' was filed at the airport police station, a senior officer said.

A police team visited the spot where the accident had happened, the officer said, adding that forensic experts will now collect evidence. 'We are talking to other staff of the airline who were present there. We are trying to understand whether it was a technical glitch or the result of someone's callousness,' the officer said.

In 2015, an Air India service engineer was killed after he got sucked into the live engine of an Aibus A319 aircraft at Mumbai airport.
