Civil Aviation Development & Discussion

There are two boxes, AFAIK, they both collect the same data points (its designed in that way to increase the chances of finding atleast one). In this event, both were recovered, so I would expect only one will be unsealed initially and the second one will be used to validate the conclusions.

pravula ji,


The opening of the black box and all connected processes there after are video graphed by multiple high definition cameras covering different views from different angles and time stamped, accompanied by running commentary in sync with the video.

“Following the tragedy of Air India Flight 171 in Ahmedabad, which took place on June 12, India's principal aviation safety watchdog, the Directorate General of Civil Aviation (DGCA), has ordered the termination of three separate Air India employees due to lapses in operational safety.”

Missed this report. IMO this explains why so many AI flights are seen to be taking no risks with technical issues.

Crash: India B788 at Ahmedabad on Jun 12th 2025, lost height shortly after takeoff, no thrust reported

On Jun 17th 2025 an official, a former Air India Captain trained by the Captain of the accident flight, stated, that the CVR has been successfully read out, the voices on the CVR are very clear. It is becoming gradually clear from the newly emerging evidence that there was probably zero negligence in the cockpit, the crew did not give up until the very last moment. The probability of a technical cause is high. A preliminary report by India's AAIB can be expected in a few days.

On Jun 20th 2025 government officials stated, that India's AAIB is currently looking into another case of dual engine problems with an A321 that happened in London Gatwick in 2020, see: Incident: Titan A321 at London on Feb 26th 2020, left engine surged, engine stall indications for right engine, that was caused by fuel contamination. It appears on preliminary findings, that there was no error in the cockpit, it appears that as soon as the flight became airborne the power failure occurred leaving the aircraft unable to climb to a safe altitude.

Found this Kanishka CVR transcript today.

As I had theorized, they are starting with only one box at a time...

There are two boxes, AFAIK, they both collect the same data points (its designed in that way to increase the chances of finding atleast one). In this event, both were recovered, so I would expect only one will be unsealed initially and the second one will be used to validate the conclusions.

Previous instance of dual engine failure, but happened after the plane was on the ground. Couldn't find more about what caused it though.

This has taken on geopolitical dimensions

[vera_k]

I hadn't made this connection yet. Air India has received many bomb threats over the last year. And this flight had a former chief minister on board.

Sabotage angle being looked into

From the above, they are being really thorough!


“…we are looking at CCTV footage of Ahmedabad over the last 30 days. Those who came and those who went through screening, all the passports,”

Govt agencies are quiet. Along with the DFDR and CVR analysis, I think a lot of clean up is happening in AI, other domestic airlines and airports. NaMo never let's a crisis go waste.
