Fault within aircraft that jet fuel switch turned off automatically: Civil aviation expert on AI171 preliminary crash report
Synopsis A preliminary report on the Air India AI171 crash indicates a potential aircraft malfunction led to the tragedy, according to aviation expert Sanat Kaul. The report suggests the fuel supply to the engines was unexpectedly cut off during takeoff, causing the crash that killed 260 people. Air India flight AI-171 crash: Aviation expert analyses AAIB's preliminary report, negates captain's fault Civil aviation expert Sanat Kaul has said that the preliminary report by the Aircraft Accident Investigation Bureau (AAIB) on the Air India flight AI171 crash suggests that "some fault within the aircraft" led to the jet fuel switches turning off automatically during takeoff, causing the tragic crash that killed 260 people, including 229 passengers, 12 crew members, and 19 people on the to ANI, Kaul said the report indicates that fuel supply to the aircraft's engines was unexpectedly cut off during takeoff."From the report I have seen, there was no other reason for the aircraft to go down but the manufacturing part; the fuel to the engine itself switched off accidentally or there was something that the pilot or the co-pilot was not aware of and the engine lost the thrust," Kaul said.

"In Boeing, it is not the first time; there were two instances of that new plane, which, after takeoff, again went down and crashed, and people died. In both these cases, it finally came out that the changes have been made in the max varieties of 737, and the pilot was not aware of the situation, and Boeing deliberately did not give training because training costs money, and they have to bear the cost," he said."There have been whistleblowers from the ones who worked in the Boeing company who said that Boeing is trying to save money on manufacturing and safety aspects," Kaul Aircraft Accident Investigation Bureau (AAIB) released the preliminary report into the tragic crash of Air India flight AI171, a Boeing 787-8 aircraft, which crashed shortly after takeoff from Ahmedabad's Sardar Vallabhbhai Patel International Airport on June 12.

"Don't think report is ok": Aviation expert Sanat Kaul questions AI 171 crash report, calls for pilot inclusion in probe panel
New Delhi [India], July 13 (ANI): Aviation expert Sanat Kaul on Sunday raised concerns over the preliminary report of the Air India 171 crash investigation, stating that it is 'not ok.' He emphasised the need for pilots to be included in the probe panel, as per the International Civil Aviation Organisation's (ICAO) charter. 'Well the report, with the National Emblem, from the Ministry of Civil Aviation is not signed, that is correct. It should have been signed. But I don't think the report is ok. We should wait for the final report, and the final report may not align with the preliminary report; there can be several changes in the final report,' Kaul told ANI here. Kaul stressed that a pilot familiar with Boeing 787 systems or at least 737 experience should be part of the investigation team. He called for the implementation of Annex 13 of ICAO's charter, outlining procedures for plane crash investigations. 'The other is that in these investigations the International Civil Aviation Organisation's (ICAO) charter has to be implemented. There has to be a team, experts. So they have a contention that no pilot is in the team, there has to be a pilot who is conversant with Boeing 787 aircraft. If they can't find a pilot with that experience, then they should have someone (having experience) with atleast (Boeing) 737,' Kaul said. The Aviation expert's remarks comes after the Federation of Indian Pilots and the Airline Pilots' Association of India also raised doubts over the preliminary report, saying that 'qualified, experienced personnel, especially pilots' are not being included in the team of experts. Kaul and the Airline Pilots' Association of India emphasised the need for qualified, experienced personnel, especially pilots, to be included in the investigation team. India is a signatory of the ICAO Chicago Convention (1944), the Ministry of Civil Aviation said in a statement on June 26 that the investigation is happening 'in accordance with ICAO Annex 13 and the Aircraft (Investigation of Accidents and Incidents) Rules, 2017.' The multi-disciplinary probe committee formed by the Central government is chaired by the Union Home Secretary and includes Secretary Ministry of Civil Aviation, Senior Officials from Home Ministry, Officials of Home Department and State Disaster Response Authority of Gujarat, Police Commissioner of Ahmedabad, Director General of Inspection and Safety in the Indian Air Force and Director General of Bureau of Civil Aviation Security. Earlier, commenting on the June 12th AI 171 crash, the Airline Pilots' Association of India said, 'The tone and direction of the investigation suggest a bias toward pilot error. We categorically reject this presumption and insist on a fair, fact-based inquiry.' 'The report was leaked to media without any responsible official signature or attribution. There is lack of transparency in investigation as investigations continue to be shrouded in secrecy, undermining credibility and public trust. Qualified, experienced personnel, especially line pilots, are still not being included in the investigation team,' the association added. The crash of Air India flight AI171, a Boeing Dreamliner 787-8, in Ahmedabad, Gujarat, claimed 260 lives, including 229 passengers, 12 crew members, and 19 people on the ground on June 12. (ANI)
