The final inquiry report has not yet come in the Ahmedabad plane crash case. However, the media of several countries including the US had reported that the reason for the Ahmedabad-London Air India Dreamliner aircraft accident was deliberately stopped the fuel supply by one of the pilots. He had made the engine switch ‘to’ cutoff ‘. This stopped fueling the engine and crashed the plane. Now an aviation expert has given his opinion in this matter and has said that it is not possible to methmatically. Ahsan Khalid, a former pilot of the Indian Air Force, said that the media should not speculate without any evidence. It is believed that the US Donald Trump is trying to save Boeing, the government of the government and the media Air India aircraft. Apart from this, it will also know on which points the investigation in this case has now focused.
The matter of deliberately closing fuel switch is wrong
The aircraft accident bureau of investigation (AAIB) is investigating the accident on June 12. A total of 260 people, including 241 people aboard the aircraft, lost their lives in this accident. Aaib recently released its preliminary report. An important thing has come out in this report. That is that fuel switches were converted within a second. Some media reports have said that this was done intentionally. However, Captain Ehsan Khalid, who was a pilot, does not agree with this. He said that this incident is very sad. We should express condolences to the families of all those who lost their lives in this accident. We should wait for the AAIB investigation to be completed so that the real cause of the accident can be known.
There are two types of switches in the aircraft, know that
Air India Dreamliner crashed in the premises of a medical college 32 seconds after 787-8 take-off. The aircraft consists of two types of switches. It has a run switch, which keeps the engine operational. At the same time, there is a second cutoff switch, which the engine stops as soon as it is pressed.
The aircraft had achieved 100 nautical miles speed
According to AAIB report, the aircraft achieved its maximum speed at 180 knots (Knots) i.e. 185 km per hour at 08:08:42 UTC. Subsequently, the fuel cutoff switches for the engine 1 and 2 went into the cutoff position by run in a interval of one second. The fuel switch of the engine 1 was brought back from the cutoff at 08:08:52 UTC. At the same time, the switch of the engine 2 was brought back to 08:08:56.
Both switches changed in cut off from run, it is not possible
The report also wrote that a pilot asked another pilot why he stopped the engine. In response, the second pilot said that he did not do so. Speaking to a news channel NDTV, expert Khalid said-I want to present a new mathematical assessment that proves stories that are going on. The fuel switch at a 42-second timent turned from ‘run’ to ‘cut-off’ within a second. This means that both switches were closed within a second. This is impossible.
The story of Western Media Report turns false
Expert Khalid said-then the story is that the other pilot saw this and asked-why did you stop the engine? ‘ If this is true, then I think the person who tells this story will now have to tell why the person waited for 10 seconds to turn back this switch. Western media reports also did not say that both pilots wanted to kill themselves.
Leave the matter of speculation, the engine closed with technical flaws
Khalid said that I think an electrical signal had closed the fuel of the aircraft. The switch was not changed at that time. Perhaps he was later changed when the pilot was trying to restart the engine to avoid the accident. However, they could not stop him. Captain Khalid believes that the pilots did not deliberate the engine. The engine was closed due to a technical fault. He also said that the media should not speculate without any evidence.
These 5 blind spots for the real cause of the accident
Command of Fuel Switch Cutoff: A duplicate test of the throttle box unit for fuel run or cutoff can be done to know whether the cutoff command was the result of electronic disturbances or there was any fault of pilots.
Timeline for the last conversation of the pilots: A pilot asked why did you stop the fuel? The other said-I did not. To understand this, it is necessary to have the same timeline of CVR (Cockpit Voice Recorder), FDR (flight data recorder).
Whether or not the cockpit voice recorder has a sound of switch: Fuel control switches include a clicking sound, which is recorded in the area mike of CVR. If the voice is not recorded, it shows that it has not been manually done.
Whether the FAA advisory was followed: Federal Aviation Administration (FAA) gave advisory on fuel switch locking mechanism in 2018. The investigating agency has sought a clearance copy from maintenance records, service bulletin logs, DGCA. Ignoring it will be negligent in serious operations.
Investigation of opening and closing of engine valves: Which sensor indicated. There is no mention of this in the initial report. It is being told that AAIB has sought the Raw data of these channels from GE and Boeing. It will also be checked whether an engine can be resumed in 32 seconds.
