Charanvir Singh Randhawa, president of the Federation of Pilot, expressed doubts on Sunday’s preliminary report on, saying that he does not clarify who had control of the cockpit and indicates possible electrical or software dysfunction on the aircraft.
Speaking to Ani, Randhawa said: “The aircraft was actually flying by the co -pilot, who was the one who controlled the plane, while the commander was watching the flight. Therefore, it is still not clear who made the basic decisions. The preliminary report does not make it clear, although it would be easy to identify from the pilot’s voice recorder who was talking. “
The change in the position of the fuel control switches
He added that the report states that the fuel control switches changed its own position on their own, which could indicate a serious aircraft problem. “The report also states that the fuel control switches have changed position, from turning off in operation on their own. This suggests that there may have been an electric or software problem. It seems that the system detected that the switch had moved, even though no one of course touched it. “
Randhawa also referred to a 2018 Boeing Counseling announcement that warned of similar fuel change problems on aircraft 737. “In December 2018, Boeing issued a consulting announcement on similar dysfunctions of the fuel control switches in some aircraft 737. controlled. This circular should have been a directive and not just a consulting announcement, “he said.
Randhawa added that he did not believe that the pilots would have moved the switches unless both engines had broken, which the report did not confirm. “I do not believe that the pilots would have moved the fuel control switches unless they knew a double engine damage causing thrust. But according to Cockpit Voice Recorder (CVR), they did not move the switches. This indicates a possible problem with the aircraft’s electronic system. “
“The preliminary report gives a clear picture but there are unanswered questions”
He also added: “However, the preliminary report seems to give a clear picture, saying that there was nothing wrong with Boeing engines or systems. But many questions remain unanswered. A proper research is needed to understand what really happened after taking off the aircraft. “
According to Randhawa, flight data show that the aircraft reached a speed of 180 knots at 08:08 for two seconds. Ten seconds later, fuel control switches either changed manually or the system recorded a change, possibly without physical intervention. He also pointed out that the landing system had not been recovered and the fins remained in the take -off position, indicating possible damage to the system.
The president of the Federation of Indian pilots said: “We know from the flight data that the plane reached a speed of 180 knots at 08:08 for two seconds. Ten seconds later, at 08:08:52, fuel control switches were either manually reset or the system detected a change, probably without physical intervention. It is also clear that the landing system had not been rebuilt and the fins remained in the take -off position. This suggests that some dysfunction may have occurred. “
“If the pilots move the switches, it might have been in response to the problem. If not, it might have been an electrical error that falsely indicated a change, “Randhawa said. “I hope that in the next phase of the study, these questions will be answered clearly. It is also important that the CVR copy determines who gave the commands to the cockpit, “Radchaua added.
It is recalled that the AI171 Air India Ai171 crash, a Boeing Dreamliner 787-8, in Ahmedabad, Gujarat, claimed the lives of 260 people, including 229 passengers, 12 crew members and 19 people on the ground.
The report on the accident
According to the 15 -page report by the India Air Force Investigation Office (AAIB), the switches in the Boeing 787 Dreamliner cockpit were found in the “Cutoff” site.
The report, according to Skynews, states that: “The engine stop switches 1 and 2 jumped one after the other from the” Run “position to the” cutoff “position with a one -second time.
“Why did you stop her?”
“N1 and N2 engines have begun to decline from take -off prices as fuel was interrupted to the engines,” the report adds.
Then there was confusion in the cockpit. In the recording of the voice, one of the pilots is heard asking the other why he “interrupted it” (ed.). The other pilot replies that he didn’t. The 15 -page report does not specify what comments were made by the commander of the flight and which of the first officer. One of the pilots made an emergency call with the characteristic slogan “Mayday” just before the crash. Both pilots were experienced, with about 19,000 hours of flight, of which more than 9,000 in Boeing 787.
