Air France Flight 4590 crashed near Paris in 2000. Learn where the Concorde crash happened, its cause, casualties and the safety changes that followed.
Air France Flight 4590, Concorde F-BTSC, crashed in Gonesse shortly after taking off from Paris Charles de Gaulle on 25 July 2000. Runway debris burst a tyre; the impact ruptured a wing fuel tank, causing a major fire and loss of thrust. All 109 people aboard and four people on the ground died.
In our Aviation & Real-World Flying coverage, the key distinction is that this was not simply an engine failure. It was a rapid chain involving runway debris, tyre destruction, fuel-tank damage, fire and inadequate thrust during the most critical part of take-off.
When and where did Air France 4590 crash?
Air France 4590 crashed at about 16:44 local time on 25 July 2000 at a hotel in Gonesse, Val-d'Oise, a few kilometres south-west of Paris Charles de Gaulle Airport.
The charter flight had departed runway 26R for New York John F. Kennedy International Airport. It remained airborne for little more than a minute before striking the Hôtelissimo Les Relais Bleus. The 109 people aboard comprised 100 passengers and nine crew members; four people on the ground were also killed and several others were injured.
What happened in the Concorde crash?
A strip of metal on the runway started a destructive sequence that the aircraft could not survive at take-off height and speed.
- A DC-10 shed runway debris: A Continental Airlines DC-10 that had departed a few minutes earlier lost a non-standard titanium wear strip from a thrust-reverser assembly.
- Concorde's tyre struck the strip: During the take-off roll, a tyre on the left main landing gear ran over the metal at high speed and broke apart.
- A tyre fragment damaged fuel tank No. 5: A large piece of rubber hit the underside of the left wing. The impact deformed the structure and created a pressure surge in the fuel, causing the tank to rupture.
- Leaking fuel ignited: Fuel escaped beneath the wing and caught fire. Investigators could not prove the precise ignition source; electrical arcing and contact with hot components were among the possibilities considered.
- Thrust and climb performance deteriorated: Both left-side engines suffered serious thrust problems. Engine No. 2 was eventually shut down after a fire warning, while Engine No. 1 repeatedly lost thrust. The landing gear remained extended, adding substantial drag.
A common mistake is to say that the titanium strip punctured the fuel tank directly. It did not. The strip destroyed the tyre, and the tyre fragment's impact transmitted enough energy into the wing and fuel to rupture the tank.
Our detailed chronology of the Concorde accident follows the sequence, casualties and subsequent safety work in a wider historical account.
What caused the Concorde Flight 4590 crash?
France's Bureau of Enquiry and Analysis for Civil Aviation Safety identified the runway strip and resulting tyre failure as the initiating cause of the Flight 4590 accident.
The investigation also exposed a serious vulnerability in Concorde's design: a large tyre fragment could strike the lower wing with enough force to rupture a fuel tank above it, even without penetrating the tank directly. The resulting fire, loss of dependable thrust and inability to retract the landing gear left the aircraft without the performance required to climb safely.
Did excess weight or a missing landing-gear spacer cause the crash?
No; investigators examined both matters, but neither initiated the tyre-impact and fuel-leak sequence.
The aircraft's estimated take-off mass was slightly above the authorised maximum, which reduced an already narrow performance margin. A spacer was also missing from the left main landing-gear assembly. These findings formed part of the full reconstruction, but they do not replace the official causal sequence beginning with the metal strip on the runway.
Why did the pilots continue the take-off?
The crew continued because the tyre hit the debris after Concorde had passed V1, the calculated take-off decision speed.
Once an aircraft is beyond V1, continuing is normally safer than trying to stop with little runway remaining. V1 is not an absolute prohibition on rejecting a take-off: a crew may still stop if the aircraft is plainly incapable of flight. In this case, however, there was no cockpit warning specifically identifying a ruptured tank, and the full scale of the fire and thrust loss emerged around rotation and liftoff.
By then Concorde was moving at very high speed near the end of the usable runway. Attempting to brake to a halt would itself have carried an extreme risk of a high-speed overrun.
Was pilot error the main cause?
No. The official investigation did not identify pilot error as the initiating cause of the Air France Concorde crash.
The report examined the crew's decisions, aircraft loading and mechanical discrepancies, as accident investigations routinely do. Those issues do not support the claim that the captain knowingly took off with a fully developed fire or could simply have stopped safely after the danger became apparent.
Why could Flight 4590 not reach Le Bourget?
Flight 4590 could not reach nearby Le Bourget Airport because it lacked the height, airspeed and dependable thrust needed to turn and land.
The aircraft remained only a few hundred feet above the ground. Its extended landing gear produced heavy drag, while the fire and uneven thrust from the two left engines prevented normal acceleration and climb. As airspeed decayed, the aircraft entered a steep left bank, lost control and struck the hotel in Gonesse.
Was Flight 4590 Concorde's only fatal accident?
Yes. Air France Flight 4590 was Concorde's only fatal accident during its commercial service from 1976 to 2003.
Concorde had experienced previous tyre failures and lower-wing damage, but none had produced this combination of a major tank rupture, sustained fire and loss of thrust. The accident destroyed F-BTSC and killed everyone aboard.
What changed after the Air France Concorde crash?
Concorde was withdrawn from passenger service while regulators, manufacturers and operators addressed the tyre-and-fuel-tank vulnerability.
- Fuel-tank liners: Flexible, impact-resistant liners were installed in vulnerable tanks to reduce fuel loss after structural damage.
- Stronger tyres: More cut-resistant tyres were introduced to reduce the likelihood of large, destructive fragments being thrown into the wing.
- Protected wiring: Electrical wiring around the landing-gear area received additional protection.
- Revised procedures: Inspection, maintenance and operating requirements were reviewed before passenger flights resumed.
Modified Concordes returned to commercial service in November 2001. The type had therefore flown paying passengers again before its eventual retirement.
Did the Flight 4590 crash cause Concorde's retirement?
No. The crash severely damaged confidence in Concorde, but it was not the sole reason Air France and British Airways retired the aircraft in 2003.
Falling premium demand, rising maintenance costs, an ageing fleet and the wider aviation downturn after September 2001 also influenced the decision. Our history of Concorde's development, return to service and retirement explains that broader context, while our account of the final commercial Concorde services separates the Air France and British Airways dates.
