The family of Jules Bianchi have launched legal action in the United Kingdom against the FIA, the Formula One Group and the Marussia team.
Bianchi sustained a diffuse axonal injury at the 2014 Japanese Grand Prix when his car left the circuit and struck a recovery vehicle, which was tending to the stranded car of Adrian Sutil.
Bianchi passed away last July, and an FIA Accident Panel investigated the incident before concluding that Bianchi had not slowed sufficiently for yellow flags.
The action is being conducted through Stewarts Law, which has issued pre-action letters to the three parties.
"Jules Bianchi's death was avoidable," said Stewarts Law partner Julian Chamberlayne.
"The FIA Panel Inquiry Report into this accident made numerous recommendations to improve safety in Formula One but failed to identify where errors had been made which led to Jules' death.
"It was surprising and distressing to the Bianchi family that the FIA panel in its conclusions, whilst noting a number of contributing factors, blamed Jules.
"The Bianchi family are determined that this legal process should require those involved to provide answers and to take responsibility for any failings.
"This is important if current and future drivers are to have confidence that safety in the sport will be put first.
"If this had been the case in Suzuka, Jules Bianchi would most likely still be alive and competing in the sport he loved today."
Bianchi's family have also announced the formation of the Jules Bianchi Society, a foundation which will aim to support young karters as they strive to climb the motorsport ladder.
