La International Automobile Federation published the result of the report he made on the accident that the Frenchman starred in Romain Grosjean, of the team Haas, during the first round of Bahrain Grand Prix last year.
With the data collected through interviews with those involved, various inspections, the analysis of the available video material and data from the vehicle's sensors and the French's ear accelerometers, the following points were determined:
-The impact between the cars lifted the rear of the Haas de Grosjean, forcing it to turn to the right and set him on a runaway trajectory in the escape zone inside the circuit at the exit of Turn 3.
-Kvyat also altered the trajectory and entered the same starting area, but was able to rejoin the track shortly after without further contact.
-Grosjean's racing car hit the triple barrier behind the start zone 192 km/h and at an angle of 29 degrees, with an estimated deviation of 22 degrees in the direction of travel and a maximum resultant force equivalent to 67G.
-After the failure of the central rail of the barrier and the significant deformation of the upper and lower rails, the survival cell was able to pierce the barrier and stopped behind it, constrained by the primary anti-roll structure, against the upper rail of the barrier.
-The car suffered major damage during impact, including separation of the power train assembly from the survival cell. The fuel tank inspection hatch on the left side of the chassis came off and the engine fuel supply connection came loose from the tank, causing the fire.
-La energy recovery system battery High-voltage (ERS) was significantly damaged, with some parts of its battery assembly remaining with the powertrain and others remaining attached to the survival cell.
-The resting position of the survival cell, relative to the upper rail of the barrier, significantly restricted the path for the driver to exit.
-Due to damage to the survival cell and a number of components within the cockpit environment, andGrosjean's left foot was initially trapped when the car stopped. The driver was able to free his foot by removing it from his racing boot, leaving the boot in the trapped position in the car and then moving both the headrest and the steering wheel to get out of the car.
-The pilot's safety equipment, including the helmet, HANS and safety harness, as well as the survival cell, seat, headrest and Halo responded according to their specifications.
Regarding the medical and rescue element of the incident, which were key to ensuring that Grosjean suffered only burns to the back of his hands, the report notes that "The FIA medical car arrived within 11 seconds of the incident, a time achieved in part due to the fact that a shortcut was taken to avoid Turn 1, demonstrating both local circuit knowledge and prior planning."
The rescue operation was immediately attended by the Dr. Ian Roberts, the driver of the FIA F1 medical car, Alan van der Merwe; and a local doctor.
“Ian Roberts immediately went to the scene of the incident and instructed a sheriff to operate the dry powder fire extinguisher around the cabin, where he identified Romain Grosjean attempting to leave. Alan Van der Merwe retrieved a fire extinguisher from the back of the FIA medical car while the local doctor prepared the trauma bag ", was explained. All of this allowed Grosjean to escape the fire in 27 seconds.
Through the analysis of this information, the FIA will carry out work in three areas that could be improved: the car, the driver's equipment and the circuits. The information collected in this incident adds to that of 18 others that took place during 2020.
