What caused the Concorde to stall & crash?

Question

I know what happened on the runway, but did the stall happen because the wing had disintegrated or was it because it could not maintain level flight on only 2 engines? - or something else?

Answer 1

After the fuel tank ruptured from the tire that burst, Then the rupture reached the several wires, after that  the wires sparked, and we know what happens when spark touches fuel, so two engines became engulfed in flames leading to the eventual stall, which too, stalled the aircraft which caused the crash of Air France 4590.

Answer 2

The official investigation was conducted by France’s accident investigation bureau, the BEA, and it was published on December 14, 2004. It concluded that the crash was caused by a titanium strip, part of a thrust reverser, that fell from a Continental Airlines DC-10 that had taken off about four minutes earlier to Houston. This metal fragment punctured Concorde's tyres, which then disintegrated. A piece of rubber hit the fuel tank and broke an electrical cable. The impact caused a shockwave that fractured the fuel tank some distance from the point of impact. This caused a major fuel leak from the tank, which then ignited. The crew shut down engine number 2 in response to a fire warning but were unable to retract the landing gear, hampering the aircraft's climb. With engine number 1 surging and producing little power, the aircraft was unable to gain height or speed, entering a rapid pitch-up then a violent descent, rolling left. The impact occurred with the stricken aircraft tail-low, crashing into the Hotelissimo Hotel in Gonesse. [6] According to the report, the piece of titanium from the DC-10 had not been approved by the U.S. Federal Aviation Administration.

Answer 3

It took some 25 years for the right circumstances to come together to show the Concorde had a design flaw.  It was determined that a metal strip which fell off of a DC-10 was the main cause of the loss of the Concorde but one thing that was not really talked about was the fact that airliners blow tires all the time and they don't crash because of it.  The Concorde has had some 70 incidences of tires explosions over the years.  That particular plane that crashed was overweight by a few thousand pounds.  That few thousand extra pounds was additional weight that bore down on the main gear tires when the pilot rotated the aircraft. The exploding tire that brought down the Concorde hit the underside of the wing but did not penetrate it.  The high speed collision of the tire fragment set up a shock wave inside the wing fuel  tank, traveled through the fuel and blew out a fuel tank access panel causing the fuel to begin flowing out of the tank and into the jet intakes.  Damaged wires in the wheel well sparked the resulting fire that began to destroy the wing.  The pilot shut down the two engines on the damaged side which is standard procedure in the case of an engine fire.  This proved fatal because he was not able to maintain sufficient airspeed to keep the aircraft aloft.

Answer 4

It was because a piece of equipment that was installed improperly on the previous aircraft that took off on the runway fell off.  And when the concord hit it, the wheel knocked it up into the fuel tank and it ruptured.  Of course the fuel comes out and catches fire.

Answer 5

A piece of debris flew up (believed actually to be the tyre fragments NOT the metal object) and ruptured the wing, causing fuel to leak out. The piece was believed to be from a Quantas 747 but this later changed to a DC-10. The fuel ignited and the engine quickly lost fuel and power.

They shut down engine 2 - which is procedure when there is an engine fire. Unfortunately engine 1 then lost power as the fuel burned up at a rapid rate.

The plane couldnt keep in the air with the loss of power and drain on the fuel. The wing held stable throughout.

The most power is required on take off, and this was a crucial time. There was no chance at all for the pilot as he had passed V1 so couldnt abandon the take off.

God bless them all.

Answer 6

A tragic incident involving catastrophic failure, and not like the typical stall/spin/crash incident at all.  Well described above.
