The FIA has claimed that Jules Bianchi "did not slow sufficiently" before his life-threatening crash at the Japanese Grand Prix.
The Frenchman is currently in a critical condition after hitting a recovery vehicle during the race on October 5.
However, the FIA's 10-man accident panel has suggested in its report that Bianchi did not do enough to avoid losing control of his car in the build-up to the accident.
"During the two seconds Bianchi's car was leaving the track and traversing the run-off area, he applied both throttle and brake together, using both feet," read part of the report.
"The Failsafe algorithm is designed to over-ride the throttle and cut the engine, but was inhibited by the torque coordinator, which controls the rear brake-by-wire system.
"Bianchi's Marussia has a unique design of BBW, which proved to be incompatible with the Failsafe settings.
"The fact that the Failsafe did not disqualify the engine torque requested by the driver may have affected the impact velocity; it has not been possible to reliably quantify this."
It was announced on Wednesday that the virtual safety car system, which was trialled in the wake of Bianchi's crash, will be enforced permanently as of next season.
Bianchi's former team Marussia recently ceased trading due to financial difficulties.
