Air India plane crash

Who are these “aviation experts…?”

Idiots





The second major fault surfaced on June 10, 2025. The NGS failure was marked as “high-risk”, or CAT A MEL, by the maintenance engineers. This fire inerter’s job is to prevent fuel-tank fires by injecting nitrogen-rich air into them to prevent a vapour build-up of the flammable gas oxygen. When the NGS is offline, oxygen levels can rise inside the fuel tanks.

As the NGS did not function in flight AI171, it meant that there was nothing to immediately slow down or suppress the fuel fire that erupted when the aircraft hit the ground. If the inerting system had done its job, the initial fire could have been smaller, and there might have been more than one survivor, say aviation experts.

That's not how NGS systems work.

It's also not how physics works.
 
AvHerald has a blurb about a Ryanair 737MAX IFSD occurring when, reportedly, a sunscreen impacted a start lever. I have difficulty both with the idea of the lightweight hardware of a Boeing-installed sunscreen doing that, as well as the spatial separation allowing that kind of interaction without some additional aggravating circumstance.

“A Malta Air Boeing 737-8 MAX on behalf of Ryanair, registration 9H-VUE performing flight FR-3505 from Krakow (Poland) to Milan Bergamo (Italy), was climbing through FL080 out of Krakow's runway 25 when a sun visor was torn off and impacted one of the engine start levers causing the engine (Leap) to be shut down. The crew declared PAN PAN, levelled off at FL100 continuing on present heading and attempted an engine restart, which was successful. The crew cancelled PAN PAN and continued the flight to Milan for a safe landing about 90 minutes later.​
​
The aircraft remained on the ground in Milan for about 50 hours, then returned to service.​
​
The BAAI Malta (Bureau of Air Accident Investigation) rated the occurrence an incident and opened an investigation.​
​
On Dec 19th 2025 the BAAI responded to an e-mail by The Aviation Herald explaining, that Poland as state of occurrence decided to not open an investigation. According to Annex 13 ICAO the state of registration is thus permitted to conduct an investigation, which Malta decided to do in the belief, that "valuable safety lessons may be learned from this event, a sentiment underlined by Boeing's significant interest in the matter." Poland has assigned an accredited representative to participate in the investigation.”​

I’ll never forget after the Asiana crash, one of those top news networks brought this “aviation expert” on who had 0 days in the airline industry. A military pilot entire career speaking and ripping on airlines (foreign ones at that). That’s when I realized the term “aviation expert” is meaningless.

During the radar outage aftermath here one of the “experts” spouted off a bunch of nonsense and one of our guys actually found his phone number and had a conversation with him about everything he said that was wrong. Dude seemed legitimately apologetic and eager to learn though so I’ll give him that.

And that’s just in the airline industry, and we know they’re wrong because it’s our field. Imagine what they and their experts get wrong in other fields, and portray that as reportable news.

There is a story that @Richman may or may not be able to share about a SouthernJets 717, an iPad (being used for company approved purposes of course), and the auto throttles moving back at the top of climb.

I can’t remember but I feel like they put a Molly-guard of some sort over them after that.

Nothing goes near the start levers / fuel levers (switches) / fuel control switches / spinny spinny levers, ffs.

Thread 'Delta 717 dual engine failure?'

So I'm out at the airport today doing a repo flight, and one of our mechanics tells us an interesting story that he says he heard from a Delta guy. According to him, a Delta 717 crew was flying and watching a movie on an iPad, and they had set the iPad up on the center pedestal resting against the throttles so they could both see it. They start an idle clamp descent and the autothrottles come all the way back knocking the iPad down and hitting the fuel switches, causing a dual engine failure. They restart the engines and everything is fine afterwards.

Any truth to this? I tried setting an...

Would anyone even notice if a 717 lost its engines?
