Vistara flight UK775, a Boeing 737-800, encountered turbulence 15 minutes before landing at Kolkata, India. Four passengers were injured.
Probable Cause of the Accident
The accident occurred as the aircraft entered into a severe turbulence instead of circumnavigating it. This resulted in serious injuries to passengers who presumably did not comply with” fasten seat belt” sign and instructions given by cabin crew.
Contributory factors to the accident were: -
➢ The flight crew was well aware about the deteriorating weather at and around Kolkata. Notwithstanding this, they continued the flight in severe weather conditions.
➢ Operator’s Operations Manual does not provide clear cut guidance to flight crew regarding circumnavigation through the enroute bad weather (weather avoidance).
➢ At any point during the flight, the flight crew did not consider diverting to an alternate airfield even though they were not sure whether the gap is clear of any clouds.
➢ Flight Dispatch did not provide any guidance to flight crew, while they were negotiating enroute weather which was not in line with the company Flight Dispatch Manual.
➢ As the aircraft was approaching the identified gap, PIC instructed cabin crew to be seated due to which the process of seatbelt compliance and securing the cabin could not be completed.
