What if the breathalyser test was fake and both pilots had been under the influence? Which might explain the inexplicable monumental mistake.
 
I'm also inclined to believe it's the pilot who did the mr bean type bonghi

He then realised what he had done put the fuel switches back to run to correct the mistake but it was too late , so asked co pilot why did you cut of the fuel has some sort of self absolvation and self guilt . And then realised he screwed up gives the distress call.
This theory is totally inconceivable.

There is no way in hell the one of the pilots could have accidentally switched these fuel cut off line because of incompetence. I will explain why.

Firstly the plane could not have taken off if the switch was on the cut off position. The fuel cut off position had occurred seconds after take off.

The most likely scenario is the trainee pilot focused on take off while the captain had discreetly cut off the switch and then played a game of reverse psychology. He then obviously put it on the on position but knew exactly what he was doing as this would have been far too late to gain any lift on a plane that was going down rapidly.

The captain deliberately crashed the plane, there is no other plausible theory around this.
 
It’s either pilot or a Boeing malfunction. In recent times, Boeing’s track record on safety has definitely raised some eyebrows. That said, mental health is no joke either, it shouldn’t be overlooked as a potential factor.

I agree that Boeing’s safety record has been very dubious lately but this
particular plane was the Dreamliner that has an impecable record.
Prior to this crash they have been running for 14 years with no fatalities.

So I will heavily rule out a technical malfunction and pilot error is the only other plausible theory but from the preliminary report that looks highly unlikely, again explained above why this doesn’t seem plausible.

I’m afraid it’s a very very likely a pilot suicide induced crash.
 
Well, it turns out the captain switched off the fuel supply to the engines as per reports in Reuters. The black box recordings substantiate this.

Money says the Captain was drunk.
 
Until anything is proven, I think we must not jump to conclusions... INvestigation is going on and so far they are blaming pilots for that engine mess up... Let's see.

Its just the most likely cause. The readouts dont show any engine failures , they spooled down after both the switches were transitioned to CUTOFF and one of the engines came back when the copilot transitioned them back to RUN
 
Indian qualified pilots reputation is at an all time low.

There are reports of PIA pilots flying under the influence in the past, but luckily none of them managed to turn the engines off during take off.

PIA pilots on aggregate are probably the worst pilots in the world. There are multiple videos of air crash investigations where the pilots have behaved recklessly and unprofessionally leading to the crash. its one thing to make a mistake (or suicide in this crash). Its another to berate your first officer and snatch controls at the last minute and totally ignore the tower.
 
Here are the facts.

The black box proves the fuel supply was cut off manually (switch triggered).

The black box proves the captain triggered the switch.

There are now 3 possibilities on why:

1 - The Captain was drunk.

2 - The Captain was incompetent.

3 - The Captain was suicidal.

In either case, Air India, and Indian pilots in general can never be trusted.

Replace AI - Air India with AI - Artificial Intelligence - and you'll have a safer airline.
 
An initial analysis of the cockpit voice recorder recovered from the Air India flight that crashed last month reveals that the younger co-pilot asked the captain why he had turned off the plane’s fuel-supply switches, according to a US media report.

First officer Clive Kunder had the controls of the Boeing 787 Dreamliner for take-off and at the time of the crash moments later outside Ahmedabad airport, according to a new report from the Wall Street Journal citing sources in the investigation, and it was he who asked flight captain Sumeet Sabharwal why he had flipped the switches, starving the engines of fuel.

It represents a potentially important new detail, emerging several days after a preliminary official report in the crash revealed only that the brief interaction had taken place, without naming who said what or quoting them directly.


Air India Flight 171 crashed into a medical college less than a minute after take-off from Ahmedabad in western India heading for London Gatwick, killing 241 people on board and another 19 on the ground. Only one passenger survived the crash.

The preliminary report, issued a month after the crash in line with international regulations, has sparked controversy with a pilots’ association accusing it of trying to place the blame on Sabharwal and Kunder without conclusive evidence.

The Federation of Indian Pilots (FIP) on Thursday said the 15-page report released lacks comprehensive data and appears to rely selectively on paraphrased cockpit voice recordings to suggest pilot error and question the professional competence and integrity of the flight cr
“Assigning blame before a thorough, transparent and data-driven investigation is both premature and irresponsible. Such speculative commentary undermines the professionalism of highly trained crew members causes undue distress to their families and colleagues,” it added.

The Journal did not say if there was any evidence that Sabharwal did move the switches, beyond the verbal exchange it cited.

But it quoted US pilots who have read the Indian authorities’ report as saying that Kunder, the pilot actively flying, likely would have had his hands full pulling back on the Dreamliner’s controls at that stage of the flight.

India's Air Accident Investigation Bureau’s (AAIB) preliminary report said the fuel switches both switched from “run” to “cutoff”, one second apart from each other, just after takeoff. It does not say how this occurred.

It said an analysis of CCTV footage shows the plane’s backup engine, known as the RAM air turbine, deployed almost immediately after the plane lifted off the ground, indicating a loss of power from the engines.

The London-bound plane began to lose thrust, and after reaching a height of 650 feet, the jet started to sink.

The fuel switches for both engines were turned back to run, and the airplane automatically tried restarting its engines, the report said.

The incident has also rekindled debate over whether planes should have video cameras in the cockpit, a demand that pilots have pushed back against.

Aviation safety expert John Nance said investigators likely would have benefited greatly from having video footage of the cockpit during the Air India flight.

Supporters of cockpit video cameras say they can help fill gaps left by audio and data recorders, while critics argue that privacy concerns and potential misuse outweigh the limited investigative benefits.

It seems that the captain either drunk or suicidal turned off the fuel to the engines. The younger pilot tried to redeem the situation but just didn't have enough elevation to get things under control. Really sad.
 
Air India received nine notices for safety violations in six months, Indian minister says

Air India has received nine show cause notices in the last six months, junior civil aviation minister Murlidhar Mohol told lawmakers on Monday, amid heightened scrutiny of the airline in the aftermath of a deadly crash.

The notices were related to five safety violations, Mohol added, without giving any details on the violations.

Air India has come under scrutiny after a Boeing 787 Dreamliner crashed in the Indian city of Ahmedabad last month, killing 260 people.

The main pilot was experiencing mental health issues. Saw it on the news.

It seems like it was a pilot-suicide or pilot's incompetence.

I expect Indian government to cover things up because that's what they often do. :inti

I think the first officer was shocked by the situation and couldnt comprehend what the pilot had done for a few seconds. Cant blame the FO because this situation must have been totally out of left field for him to even realise that the pilot had just doomed everyone on the plane.

But there were 10 seconds between the switches being turned off and back on. If one engine had been turned on quicker, there was a small chance the engine relighted a bit quicker and the plane gained some thrust back
 
The voices in the cockpit fuelling controversy over Air India crash

When the preliminary report into the crash of Air India Flight 171 - which killed 260 people in June - was released, many hoped it would bring some measure of closure.

Instead, the 15-page report added fuel to a firestorm of speculation. For, despite the measured tone of the report, one detail continues to haunt investigators, aviation analysts and the public alike.

Seconds after take-off, both fuel-control switches on the 12-year-old Boeing 787 abruptly moved to "cut-off", cutting fuel to the engines and causing total power loss - a step normally done only after landing.

The cockpit voice recording captures one pilot asking the other why he "did the cut-off", to which the person replies that he didn't. The recording doesn't clarify who said what. At the time of take-off, the co-pilot was flying the aircraft while the captain was monitoring.

The switches were returned to their normal inflight position, triggering automatic engine relight. At the time of the crash, one engine was regaining thrust while the other had relit but had not yet recovered power. The plane was airborne for less than a minute before crashing into a neighbourhood in the western Indian city of Ahmedabad.

Several speculative theories have emerged since the preliminary report - a full report is expected in a year or so.

The Wall Street Journal and Reuters news agency have reported that "new details in the probe of last month's Air India crash are shifting the focus to the senior pilot in the cockpit".

Italian newspaper Corriere della Sera claimed that its sources had told them the first officer repeatedly asked the captain why he "shut off the engines".

Air India plane descending moments before crash

Sumeet Sabharwal, 56, was the captain on the flight, while Clive Kunder, 32, was the co-pilot who was flying the plane. Together, the two pilots had more than 19,000 hours of flight experience - nearly half of it on the Boeing 787. Both had passed all pre-flight health checks before the crash.

Understandably, the wave of speculative leaks has rattled investigators and angered Indian pilots.

Last week, India's Aircraft Accident Investigation Bureau (AAIB), the lead investigator, stated in a release that "certain sections of the international media are repeatedly attempting to draw conclusions through selective and unverified reporting". It described these "actions [as] irresponsible, especially while the investigation remains ongoing".

Jennifer Homendy, chairwoman of the US's National Transportation Safety Board (NTSB), which is assisting the investigation, said on X that the media reports were "premature and speculative" and that “investigations of this magnitude take time".

Back in India, the Indian Commercial Pilots' Association condemned the rush to blame the crew as "reckless" and "deeply insensitive", urging restraint until the final report is out.

Sam Thomas, head of the Airline Pilots' Association of India (ALPA India), told the BBC that "speculation has triumphed over transparency", emphasising the need to review the aircraft's maintenance history and documentation alongside the cockpit voice recorder data.

At the heart of the controversy is the brief cockpit recording in the report - the full transcript, expected in the final report, should shed clearer light on what truly happened.

A Canada-based air accident investigator, who preferred to remain unnamed, said that the excerpt of the conversation in the report presents at several possibilities.

For example, "if pilot 'B' was the one who operated the switches - and did so unwittingly or unconsciously - it's understandable that they would later deny having done it," the investigator said.

"But if pilot 'A' operated the switches deliberately and with intent, he may have posed the question knowing full well that the cockpit voice recorder would be scrutinised, and with the aim of deflecting attention and avoiding identification as the one responsible.

"Even if the AAIB is eventually able to determine who said what, that doesn't decisively answer the question 'Who turned the fuel off?'".

"We may even never know the answer to that question."

Investigators told the BBC that while there appeared to be strong evidence the fuel switches were manually turned off, it's still important to keep "an open mind".

A glitch in the plane's Full Authority Digital Engine Control (FADEC) system - which monitors engine health and performance - could, in theory, trigger an automatic shutdown if it receives false signals from sensors, some pilots suggest.

However, if the pilot's exclamation - 'why did you cut-off [the fuel]?' - came after the switches moved to cut-off (as noted in the preliminary report), it would undermine that theory. The final report will likely include time-stamped dialogue and a detailed analysis of engine data to clarify this.

Speculation has been fuelled less by who said what, and more by what wasn't said.

The preliminary report withheld the full cockpit voice recorder (CVR) transcript, revealing only a single, telling line from the final moments.

This selective disclosure has raised questions: was the investigation team confident about the speakers' identities but chose to withhold the rest out of sensitivity? Or are they still uncertain whose voices they were hearing and needed more time to fully investigate the matter before publishing any conclusions?

Peter Goelz, former NTSB managing director, says the AAIB should release a voice recorder transcript with pilot voices identified.

"If any malfunctions began during take-off, they would be recorded in the Flight Data Recorder (FDR) and would likely have triggered alerts in the flight management system - alerts the crew would almost certainly have noticed and, more importantly, discussed."

Investigators are urging restraint in drawing conclusions.

"We have to be cautious because it's easy to assume that if the switches were turned off, it must mean intentional action - pilot error, suicide, or something else. And that's a dangerous path to go down with the limited information we have," Shawn Pruchnicki, a former airline accident investigator and aviation expert at Ohio State University, told the BBC.

At the same time, alternative theories continue to circulate.

Indian newspapers including the Indian Express flagged a possible electrical fire in the tail as a key focus. But the preliminary report makes clear: the engines shut down because both fuel switches were moved to cut-off - a fact backed by recorder data. If a tail fire occurred, it likely happened post-impact, triggered by spilled fuel or damaged batteries, an independent investigator said.

Last week, AAIB chief GVG Yugandhar stressed that the preliminary report aims to "provide information about 'WHAT' happened".

"It's too early for definite conclusions," he said, emphasising the investigation is ongoing and the final report will identify "root causes and recommendations". He also pledged to share updates on "technical or public interest matters" as they arise.

Summing up, Mr Pruchnicki said the probe "boils down to two possibilities - either deliberate action or confusion, or an automation-related issue".

"The report doesn't rush to blame human error or intent; there's no proof it was done intentionally," he added.

In other words, no smoking gun - just an uneasy wait for answers that may never even fully emerge.

Air India crash victim's son says he received 'other' remains

The son of a woman killed in the Air India plane crash has told the BBC "other remains" were found in her casket after her body was returned to the UK.

Miten Patel, whose father also died in the crash, said the coroner identified the mixed-up remains and left him to worry: "How many others are in there?"

The Daily Mail reported on Wednesday that the wrong bodies were being sent to loved ones following the crash which killed 260 people shortly after take-off in early June.

All remains were handled with "utmost professionalism" and dignity, India's foreign ministry said, and that it was working with UK officials to address concerns.

A spokesperson for the UK government said: "Formal identification of bodies is a matter for the Indian authorities.

"We continue to liaise with the Government of Gujarat and the Government of India on behalf of the Inner West London Senior Coroner to support the coronial process."

Ashok and Shobhana Patel were travelling home to visit their sons and grandchildren on 12 June. After the Gatwick-bound plane crashed in Ahmedabad, western India, they were among the first victims to be returned home.

Their son, Miten, said the mix-up was "obviously very upsetting," even though he acknowledged that mistakes happen.

"People were tired and there was a lot of pressure. But there has to be a level of responsibility that you're sending the right bodies to the UK.

"How do I know there aren't other remains in the casket with her?"

The Daily Mail reported two cases in which the wrong remains were allegedly returned to loved ones in the UK.

One apparently saw a family receive the wrong body entirely, while another was said to involve the remains of several people placed in the same casket.

India's foreign ministry said that they were aware of the report "and have been working closely with the UK side from the moment these concerns and issues were brought to our attention".

The statement continued: "In the wake of the tragic crash, the concerned authorities had carried out identification of victims as per established protocols and technical requirements.
