Overnight repairs at AlphaTauri saw the team break curfew following the opening day’s running of the 2021 Formula 1 Season.

Yuki Tsunoda suffered an unconfirmed problem late in Free Practice 2 for the Bahrain Grand Prix.

It forced the Japanese driver to park his AT02 with 10 minutes remaining in the session and prompted a long night for the team.

The breach was confirmed by the stewards.

“Last night team personnel of the Scuderia AlphaTauri Honda team, who are associated with the operation of the car, were within the confines of the circuit during the nine and a half hour period which commenced at 02:30 on 27 March, twelve and a half hours before the scheduled start time of P3 and ends three hours before the scheduled start time of P3 at 12:00 on 27 March,” a note from Jo Bauer, the FIA’s Formula 1 technical delegate, stated.

“This was the first of the two individual exceptions permitted for the Scuderia AlphaTauri Honda team during the 2021 Formula One Championship season and therefore no action should be taken.”

AlphaTauri enjoyed a promising opening day of running, with Tsunoda and Pierre Gasly both displaying solid pace across the two 60-minute sessions.

Final practice for this weekend’s grand prix takes place at 23:00 AEDT this evening, followed by qualifying from 02:00 AEDT on Sunday morning.
