Everyone TOI spoke to said what happened mid-flight was indeed "a close shave". The flight data recorder will reveal mechanical failures, if any, and the cockpit voice recorder will reveal what transpired on the flight deck. "Airbus is sending its team to India, and they will reach by Wednesday to inspect the aircraft and work with Air India and AAIB.Being a serious incident, the investigator of the original equipment manufacturer's country (France in this case) is also coming," said a source. We are actively supporting the airline and will provide further information as it becomes available".Industry executives said the A320 (VT-EXO) may have suffered a triple hydraulic failure for a few seconds, which is rare. The flight data recorder will reveal the timestamps of the sequence of events - whether the alleged transient hydraulic failure occurred because of the aircraft's rapid descent or whether the aircraft first entered an air pocket and subsequent turbulence caused hydraulic failure.
