The Lewis Hamilton and Max Verstappen F1 title drama is on.
An inquiry into last year's Abu Dhabi Grand Prix has been outlined by Formula 1's governing body.
Lewis Hamilton lost the title to Max Verstappen because the race director did not apply the rules correctly.
The sporting directors from the Formula 1 teams and the drivers are going to be meeting with the FIA.
Next month, it will present its findings to F1 bosses.
On the eve of the new season, final decisions will be announced.
This week it was revealed that Hamilton will not make a decision on his Formula 1 future until he sees the results of the inquiry.
The events of Abu Dhabi have caused Hamilton to lose trust in the governing body, and they need to take action to get him back.
In the aftermath of the race, the FIA admitted that the controversy was tarnishing the image of F1.
The inquiry will have two key stages, led by the secretary general of the FIA.
The sporting directors of all the F1 teams will meet on January 19 to discuss the use of the safety car.
There will be a discussion with all F1 drivers after that.
The outcome of the detailed analysis will be presented to the F1 Commission in February, and final decisions will be announced at the World Motor Sport Council in March.
The new president of the FIA asked Bayer for proposals to review and improve the organisation of the F1 structure.
Hamilton will need to make a decision on his future before the first pre-season test, which is on 23-25 February, so he will be in a difficult position.
The first day of track action at the season- opening race in Bahrain will be known before the official announcement on 18 March.
"Hamilton will have an opportunity to discuss the matter with the people leading the process, because there will be a meeting with the drivers," the spokesman said.
The direction of travel will begin to emerge by the time of the meeting of the F1 Commission, which comprises the teams and representatives of the F1.
The plan is for it to be held in early February but no date has been set.
Changes to key officials will be obvious to F1 teams long before the start of the season.
Masi's position is under scrutiny.
Wolff accused the Australian of a "freestyle reading of the rules" which he said robbed Hamilton of the title. Many senior figures in F1 don't think Masi can survive this inquiry.
The future of F1 single-seater head is in question.
Wolff is said to be meeting Ben Sulayem on Friday to discuss the Abu Dhabi race.
