Williams has been summoned to a meeting with the Australian Grand Prix stewards on Sunday morning, after failing to inform the FIA it intended to change the gearbox on Lance Stroll's car.
Stroll crashed in the closing minutes of Saturday morning's final free practice session, damaging the right hand side of the car and forcing a gearbox change.
While the team worked flat out to get Stroll's car repaired in time for qualifying – with the Canadian rookie making it out for Q1 before ending up 19th overall – it failed to inform the FIA of its plans to change gearbox.
Article 23.5 of F1's Sporting Regulations states that following consultation with a team each time a new gearbox is fitted, FIA seals are supposed to be attached the first time it is used to ensure that no significant moving parts can be rebuilt or replaced.
Since the FIA was not notified officially of Stroll's gearbox change, the provisional grid issued by the governing body on Saturday night had the Canadian starting in 19th – rather than at the back as the result of a five-place grid penalty.
The Williams meeting with the FIA will take place at 11.30am on Sunday.
