The Real Reason for the Crash of Air France Flight 4590

concorde-crash flight 4590

Concorde pilot John Hutchinson presents clear evidence that the French authorities, who conducted the crash investigation, covered up the true cause and tried to blame Continental airways engineers and design weaknesses in Concorde.

Air France Flight 4590 was an international charter flight, from Charles de Gaulle Airport, Paris to John F. Kennedy International Airport, New York, flown by an Aérospatiale-BAC Concorde. On 25 July 2000 at 15:43 UTC, the aircraft serving the flight (registration F-BTSC) crashed on take off.

Chain of Events

F-BTSC was in maintenance prior to this flight. The left main landing gear was disassembled to correct a problem. When reassembled, a wheel spacer was not reinstalled and was found still sitting on a shelf after the crash. The aircraft had done four flights with this defect prior to the crash so it wasn’t the prime cause.

The cause of the crash was pilot error.

The Captain overrode procedure and ordered the tanks to be filled to the brim instead of the normal 80%. He ordered more fuel than was required to be put in the aft tanks used for taxiing. He allowed 19 bags, that had not been weighed, to be loaded in the aft hold. All this made the aircraft over weight and the center of gravity out of limits.

Presumably due to the weight and balance being out of limits he requested to use the runway extension, even though it was officially closed because it was being re-surfaced. He also elected to take off with an 8 kt tail wind.

On take off the aircraft struck the ledge as it left the overrun and came on the to the runway. The effect was not unlike driving your car over a square curb at a 90 degree angle. This caused the wheels of the left main gear to turn 90 degrees to the left as they had no spacer to constrain them. The tires overheated and burst starting the fire.

The malfunctioning gear and burst tire forced the aircraft to slew to the left. It was then that it struck a runway light. Debris from the light struck the underside of the left wing. This caused a shockwave in the fuel of the over-filled tank. Fuel spewed from the bottom of the wing which was set on fire by the tire fire.

At this point the aircraft was past V1 speed of 180kts and the Captain was committed to the takeoff. As the aircraft climbed off the runway, the Left Engine Fire Light came on. The co-pilot incorrectly shut down the engine. The fire light was false because the fire was overheating the engine. Although the engine was overheating, it was still performing at 100%. The correct procedure for an overheat would be to continue operation until the aircraft safely airborne and then shut down the engine.

Once airborne, with the center of gravity shifted further aft by the escaping fuel, lack of full engine power and being overweight, the aircraft stalled and crashed..

113 people were killed in the crash.
100 passengers
9 crew
4 people on the ground.

Co-pilot: “Le Bourget, Le Bourget.”
Pilot: “Too late (unclear).”
Control tower: “Fire service leader, correction, the Concorde is returning to runway zero nine in the opposite direction.”
Pilot: “No time, no (unclear).”
Co-pilot: “Negative, we’re trying Le Bourget” (four switching sounds).
Co-pilot: “No (unclear).”
Control tower: “De Gaulle tower from fire service leader, can you give me the situation of the Concorde?”

Harold the Crane Operator

Harold
This is Harold.



Not the guy in the man lift but the one behind him in the wheelchair on the sidewalk. He stays in the nursing home across the street from where we’re building. Since day 1 when I arrived on this job site I’ve noticed him sitting there every morning from 7am he takes lunch when we do and doesn’t leave until I shut the crane down and head out. I originally had thought to myself, “He’s just a curious old man and wanting to enjoy his days outside vs being cooped up in his room.”

Well after a couple days, I myself got curious, so I walked over and introduced myself to him. We had a long conversation, two and a half hours worth, but long story short Harold is nearing the end. His heart valves are clogged and some disease has been eating at him for years. ( I don’t know the name of it) and when he was able to work before everything had happened to him health wise he was a crane operator. He said he enjoys seeing what he use to love to do for a living and never thought he’d ever be able to see or be around a crane again and let alone be so close to see one in action. He has family, 2 daughters and a son who haven’t seen him for the last 7 years he’s been in a nursing home.

So I made Harold an a deal! He originally wanted to be put on payroll 😂 as I explained to him that wasn’t possible I quickly came to what I thought was a fair agreement. Our deal is this, Harold ran cranes for over 50 years and no matter how good you think you are at something there’s always more to learn. So I told Harold every day after work I’ll sit with him for a little bit so he can critique me and judge me on how I did for that day (give him something to talk about that he enjoys) while I also get to learn from him and In return I would bring him a black coffee every morning for as long as I’m here and buy him lunch twice a week from wherever he chooses….. he didn’t skip a beat before ABSOLUTELY! came out of his mouth ❤️

I guess I’m writing this post because if I would have never walked over to him i would have never gotten to know him. I’m thankful to have the opportunity to make this mans last days enjoyable. Filled with purpose and to be able to help him smile again. I challenge any of you on here to not be like I was in the beginning and don’t be afraid to make someone else’s day better. Always try to enlighten someone’s spirits. When God chooses to take this man home I’m happy knowing that I’ve been placed here at this location to make his days better. I’m happy with that❤️
