Tragic Crash Of Flight AI-171: Investigating Engine Failures And The Role of RAT | #brasstacks

I think it looks like the maintenance worker must have tampered some of the wiring. I’m very suspicious. They need to question all maintenance workers???????

A misconfiguration of the Boeing 787's flight computer for approach instead of takeoff could lead to serious operational issues. Here’s what might happen:
- Incorrect Autopilot Behavior: The aircraft might attempt to follow descent profiles rather than climb, causing confusion for pilots.
- Flap and Slat Settings: Approach settings typically involve extended flaps and slats, which could create excessive drag and hinder acceleration.
- Throttle and Autothrottle Issues: The system might set lower thrust levels suited for landing rather than the high thrust needed for takeoff.
- Altitude and Speed Targets: The flight computer could prioritize descent speeds and altitudes, potentially leading to an unsafe flight path.
- Warnings and Alerts: Modern aircraft have safeguards that would likely trigger alarms, prompting pilots to take corrective action

What about sudden reverse engine thrust as a result of sabotage by rogue intelligence of an enemy country?

Hard to understand what he said.!

Hydraulic falure left engine over heating

Where is your best friend captain steeeeeeeeve whom you gave a platform to blame the pilots?

AI 171 ?
RAT ?
WORLD SAFEST COMMERCIAL MODEL AIRCRAFT ?

anytime that ram air turbine pops out is because they lost all hydraulic power which means the engines shut off

What we know is there was a loss of thrust, the RAT deployed,so we had loss of the A/C electrical power from Engines.

DISAGREE. PILOT ERROR IS A CONTRIBUTION FACTOR: The Air India B787 used the entire 11,500 ft runway when about 60% of that length was required for take off. This indicates a degradation of thrust and or improper take off flap setting. When the aircraft rotated at the end of the runway, you can see dust being blown by jet wash indicating the engines were running (*It is important to note, just because the flying pilot rotated at the end of the runway does not mean they reached Vr rotation speed). The RAT theory does not hold water. There are pictures of the RAT extended on take off climb. With a "breathing" airplane, RAT deployment does not prevent landing gear retraction. The engines were clearly operating during climb and level off. The airplane DID NOT have a simultaneous dual engine failure. If so, the airplane would have quickly run out of energy / speed and an aerodynamic stall would have occurred. The airplane clearly did not stall. IN REVIEW: Due to poor take off acceleration rate, the captain should have rejected / aborted the take off. Despite the RAT being deployed during climb out, the engines were operating and landing gear retraction was possible. The crew neglected to raise the landing gear (Yes, I am aware of the main landing gear truck forward angle). The accident could have been prevented if the captain rejected the take off. Once airborne, retraction of the landing gear could have prevented loss of lift.

POSSIBLE ALTERNATE THEORY: Sometime after V1 (decision speed), the 787 experienced a catastrophic electrical failure. When this occurs, the auto throttles are disengaged, EFIS (Electronic Flight Instrument System) disappears, and the FMC (Flight Management Computer) dumps all navigation and performance data. The throttles must now be operated manually by the pilot and the crew must adhere to basic minimum speed restrictions which are rote memory items. The emergency bus will eventually restore some flight instruments including operation of the radio. This failure WILL NOT inhibit landing gear retraction. It is possible this catastrophic failure overwhelmed the crew. There were no performance data available (I.E. V speeds, etc.). Instead of aborting the take off, the captain continued the take off roll. Full power had not been set by the TOGA / FMC system which resulted in degraded thrust. The CA did not manually add maximum power resulting in degraded acceleration. The flying pilot used the entire runway because they had not reached Vr and probably rotated below rotation speed. The crew NEVER manually increased maximum power and neglected to raise the landing gear.

Note: This is a plausible hypothetical. A simultaneous dual engine failure is near impossible without purposeful intent. With the exception of providing thrust for lift, the airplane appeared to be totally controllable. There was no rudder displacement, yaw moments, etc. There was a slight drift left of center line which is common when pilots are absorbed with other issues. There was no indication of stall or any loss of control of the airplane.

Maintenance

Why couldn't they fly back then with the RAM

The saviour knows everything he's behind all this

Aviation experts know the engine is at poor performance on ground itsrlf as it lift off end of runway, pilot missed to abort as he had no tunway left, if they had done takeoff roll from aother end of runwdy they would've have got sufficient runway to abort. Pilot negligence to notice systen degradation on ground

WHERE IS AT LEAST ONE OFFICIAL PRESS CONFERENCE ??????

Was the RAT found in the deployed position? What does the Flight Data Recorder say about the RAT?

I think problem is God's pictures were not put in the plane like in every politic campaign so God did not like and it happened

How long can these planes last? I know they have maintenance but constant use causes wear and tear.

It's not called a 'ram aviation turbine' its name is a 'ram air turbine', which is fairly self explanatory in regards to its function.

Holey Moley:

This man does a great job.! Good on you Sir!
Many North American racists like to mock learned people with Indian accents.
Please stop; listen to what they say. Listen, learn and adust you attitudes!

So is it safe to fly on a 787?

With a heavy aircraft possibly overloaded, hot temperature ( low air density ) and even if the aircraft didn't breach the end of the runway, that dust could have been blown on to the runway from previous aircraft taking off !!! Fine dust particles are nasty for modern high-bypass turbofans like the Trent 1000 or GEnx on the 787. These engines are designed to resist ingestion but aren’t immune, especially if the airflow is already disturbed or the engine is near the edge of its performance envelope. Stall margins shrink and even slight compressor disturbances could lead to "no thrust" symptoms or reduced engine performance when operating near the edge of their performance envelope, as in hot and heavy conditions, dust can shrink stall margins and cause compressor disturbances. This might explains the lack of thrust symptoms, validating the theory that dust could have been a critical factor.

Some studies have apparently shown that after sand and dust ingestion tests, engine power loss can be in the range of 10-15% or more. One study specifically mentioned an 11.33% power loss and a 6.05% increase in specific fuel consumption after a sand and dust ingestion test on a turboshaft engine. OK so that 10% power loss of an aircraft already at its performance limits having taken a full runway length to get airborne, could have been the determining factor of whether the aircraft after pitching up to climb with increased induced drag, might have pushed it beyond the flight envelope, causing a massive unrecoverable stall. RAT deployed due to electrical bus load shedding or transient engine electrical instability.

Boeing needs to stop making planes.

It should be wrong to say that RAT is deployed when both engines fail.

RAT is not an engine, it is a dynamo generating electrical power. This must be deployed when there is electrical power failure. There are batteries in aircraft and failure of engines will not disrupt electrical power for quite some time… may be 15 minutes to 30 minutes power back up is there.

The electrical circuit has failed causing deployment of RAT.

Boeing 787 Deathliner.

The fuel contamination/ or other issues related to it like heat is the most likely explanation today.

India is deeply stressful for planes ,too hot ,too dusty ,too chalta hai attitude about maintenance, too heavy passenger luggage,too heavy usage ,too demanding management and clueless regulators ,what can go wrong ?

Why only Air India has such issues with 787 and not other countries?

So, you should know that the “dust cloud” seen right after takeoff, at the end of the runway, was actually a massive fuel leak that was sprayed into the air, appearing to be a layer of sand that rose after the plane passed over it... Something that was on the runway made a cut in the structure of the plane, damaging the hydraulic control lines, which is why the landing gear could not be retracted. At that moment of rupture, of the fuel leak, the engines lost power and shut down. It was at that moment that the RAT went into action, the rest of the events you already know...

Hi there was a crash 1987 from Detroit to Phoenix Northeast Airlines The Pilots Forgot to Extend the Flaps and Slats the flight crashed soon after take off , SpanAir 2008 from Madrid to Canary islands the Pilots forgot the checklist and forgot the Flaps& Slats .Initial Thrust of Fixing the direction and Speed and angle is always with the Pilot, he Gauges this should be the pressure and the Auto Pilot gets Set there and once take off the Auto Pilot can't be changed this is Dream liner first crash also it really amuses that both engines can fail at same time as this is a new airline surprised.
The whole point the initial thrust could have had been more better as even after take off the back of the airline was still dipping down

I am a medium, and I feel like the captain is connecting to me. He is in disbelief as to what happened. I see him holding his head and disbelief like he can’t believe what happened. He mentioned something about a propeller, but I don’t know what that would mean in relation to an airplane. He didn’t have time to react. Everything happened so fast. When I first asked what happened when it first happened. The words thrust and loss came to me. Then it was validated when they released his Mayday call. I don’t know what a propeller is on an airplane. Maybe somebody can explain what he may be trying to communicate.

It was the high temp outside

RATが展開されても機能しない状態だった。
飛行機から物体が落ちる映像があるがこれは何？
テロで何か爆発したんじゃないのか？

Why are people still trying to troubleshoot the problem when the pilot told them what happened before he died?

It came out out of his mouth, you idiots

Find out the official source first

As a Boeing investigator, let me be clear:

There is no evidence of sabotage, pilot error, or terrorism in this incident. Preliminary data indicates a catastrophic dual engine power failure. With both engines offline, all primary hydraulic and electrical systems lost redundancy. The Ram Air Turbine (RAT)—the fourth-level emergency power source—was deployed as designed to restore minimal flight controls.

The critical question is: Why did RAT deployment fail to sustain flight integrity?

That is the question bloggers and commentators should be urging their audiences to explore—not to speculate, but to understand the complexity of emergency systems and the narrow margins pilots must operate within when all else fails.

Let certified experts handle the analysis. Let the public focus on facts.

Most, if not all, planes taking off emit a smoke haze from the rear of each jet engine as they are being fueled at a high rate to make THRUST. First thing I noticed in all videos was NO SMOKE HAZE, which to me says NO FUEL INTO JET ENGINES. AND then the RAT tries to auto correct the situation.

..Why Did They Roll Rotate TakeOff..If They Were Spooling Back..

..Why Did They Not Reject Abort Take Off..

..If RAT Deployed On ClimbOut..Engines Were Outing On The Runway..

They had thrust issues before leaving the ground. Evidence: They had to use the entire 11k foot runway to rotate. It had nothing to do with flaps. If flaps not configured correctly, alarms would have been screaming. And flaps are only fully extended during landing not take off.

Now that they have all recovered the Black Box , the experts might have already extracted the data. The only issue left is the surprise n shock from their BEAUROCRATIC WAY of Reporting.

In think the RAT in dreamliner arroplanes is more like a couple of emergency propellers. The RAT propellors mostly on on automation. Automation sensors mostly accurately sense that there is a fouble engine. faulure. The purpose ofbsmall ww2 era propellors may be to help pilotsvmake a sliding silent plane go further, to make a plane go a mile or two further in case of engine trouble. This way a pilot can glide further, on to an open field or a straight road or highway, just a few miles or so ahead.

back in 1970 i flew from AUS to the UK all hand luggage was taken from passengers' ,that was with UGARSLARV hair line's the luggage followed on behind in a separate plane with no passengers if that had been done in this instance we wouldn't be talking about this now, but like all big companies they wont spend money. i rest my case. 😡

No room for Pilot error here. The loss of height immediately after takeoff is a huge pointer to a subsystem failure....electrical or hydraulic that ruined the engine performance. I cannot believe a misalignment of the flaps as that is an error which these hugely experienced could not have done under any circumstances.
All Dreamliners must be grounded at once,and subjected to thorough scrutiny by a non Boeing team.
The RAT deployment itself is a symptom and was triggered off by the subsystem failure. At the low height in any case the RAT would have done nothing significant by way of avert the crash.
