Eighteen individuals, together with the pilot and co-pilot, had been killed when the plane, making an attempt to land in torrential rain on Friday night time, overshot the tabletop runway at Kozhikode and plunged about 35 toes right into a valley.
The investigating group retrieved the black field and cockpit voice recorder after slicing into the floorboard of the cockpit. These gadgets, thought of crucial proof in figuring out the explanations resulting in an air crash, had been despatched to Delhi for decoding and evaluation.
Officials of the AAIB, Directorate General of Civil Aviation (DGCA) and the flight security division of Air India Express from Delhi reached the crash web site on Saturday morning. A DGCA group from Chennai, too, arrived in Kozhikode. The investigators, who visited the ATC and held conferences with totally different companies on the airport, refused to touch upon the accident.
A senior official related to the probe stated it was too early to say whether or not the accident was the results of a technical fault or human error. “All crashes are attributable to a number of contributory components and right here preliminary data exhibits fallacious touchdown attributable to dangerous climate as a motive. The about 8,000-foot-long runway of the airport is ample for a Boeing 737 to land however it’s learnt that the plane landed 3,000 toes off. What precisely occurred might be clear solely after checking the flight historical past and ATC-pilot communications,” the official stated.
Aviation specialists visualised varied eventualities about what might have led to the accident, starting from hydroplaning (complete lack of friction between the wheels and runway floor as a result of formation of a layer of water on the bottom) to “optical illusions” created by tabletop runways that may distort the flight profile.
Experts additionally identified that the last-minute change in alternative of runway and subsequent wind path was the pilot’s determination or ATC’s suggestion. There had been unconfirmed studies of hassle with the touchdown gear of the plane, however, if that was the case, this was not communicated to the ATC. “The inquiry report ought to discover out all features, like climate, wind issue, poor visibility, miscommunication with ATC if any, and so on.,” stated Bharat Bhushan, former DGCA chief.
Civil aviation minister Hardeep Singh Puri, who visited the crash web site on Saturday morning, informed reporters, “Let’s not speculate on the trigger(s), contributing components of the crash, and look ahead to the results of the investigation. We had been lucky that in contrast to the tragic accident at Mangaluru airport 10 years in the past, the place the plane caught fireplace, right here preventive motion minimised the lack of lives.”
The report of the two-year-long investigation into the Mangaluru air crash in 2010, which killed 158 individuals when an AIE Boeing 737 careened off the tabletop runway, had urged varied measures, together with an arrester mattress, for tabletop runways. An “Engineered Materials Arresting System”, or EMAS, can scale back the severity of a “runway tour”, however the Kozhikode airport nonetheless doesn’t have such a system.
A DGCA inspection of the Kozhikode runway in 2019 had revealed considerations like “extreme rubber deposits” and had discovered cracks and stagnating water on components of the runway.
