The Aircraft Accident Investigation Bureau (AAIB) on Saturday released its probe report into the plane crash at Kozhikode airport in August last year that killed at least 20 people and injured several others.
The probable cause of the accident was non-adherence to the standard operating procedure by the pilot flying the aircraft but the role of systemic failures as a contributory factor cannot be overlooked, the 257-page report said.
The crash of Air India Express' B737-800 aircraft happened on August 7 at the Kozhikode airport in Kerala. The plane coming from Dubai had overshot the runway at the airport and later broke into pieces. There were 190 people onboard the ill-fated aircraft and at least 20 people, including the two pilots, were killed and several others were injured.
The report, released little over a year after the deadly crash of the Air India Express plane, said the "probable cause of the accident was the non-adherence to SOP (Standard Operating Procedure) by the PF (Pilot Flying)".
The PF continued an unstabilised approach and landed beyond the touchdown zone, "half way down the runway, in spite of 'Go Around' call by PM which warranted a mandatory 'Go Around' and the failure of the PM to take over controls and execute a 'Go Around'", it noted.
According to the report, the investigation team is of the opinion that the role of systemic failures as a contributory factor cannot be overlooked in this accident.
"A large number of similar accidents/ incidents that have continued to take place, more so in AIXL, reinforce existing systemic failures within the aviation sector.
"These usually occur due to prevailing safety culture that give rise to errors, mistakes and violation of routine tasks performed by people operating within the system. Hence, the contributory factors enumerated below include both the immediate causes and the deeper or systemic causes," it added.
On Thursday, Civil Aviation Minister Jyotiraditya Scindia said the report would be made public in the next couple of days.
"Whatever steps that have been advocated on the basis of that report, those steps will be and has to be executed ... within the ministry, we will be also putting together a group of people that will be tasked with the responsibility of ensuring that the steps that have been recommended in the report are put in place at the airport," the minister had said.
Last month, Minister of State for Civil Aviation V K Singh told the Lok Sabha that final compensation offers have been made to all the next of kin of the deceased passengers, but none of the "next of kin has sent their acceptance as of date".
"Final compensation offers have been made to all the 165 injured passengers, out of which 73 passengers accepted the offer and have been paid a total amount of Rs 60.35 crore as the final settlement as of date," he had said.
