The Aircraft Accident Investigation Bureau (AAIB) Thursday formed a five-member committee to probe the Air India Express accident at Kerala's Kozhikode airport. The committee will preferably submit its report in five months, the bureau said. In a statement, the bureau said, "The investigator-in-charge will complete its inquiry and submit the report to AAIB, India, preferably within five months from the date of the issue of this order." Captain SS Chahar, a former designated examiner on B737NG (aircraft), will be the investigator-in-charge to inquire into the circumstances of the August 8 accident. He will be assisted by four other investigators, the AAIB said. The Air India Express flight from Dubai, carrying 190 people, including a six-member crew, overshot the tabletop runway while landing at the Kozhikode airport in heavy rains on August 7 evening. At least 18 people were killed in the accident, including both pilots.
