Tim Goss, the single-seater technical director at the FIA, has bid adieu to his role, marking the departure of the third high-profile figure in the past month.
The FIA has appointed Tim Malyon, who has served as the safety director since 2021, to step into Nielsen's shoes.

"We are disappointed to lose a person of Tim's calibre from the organisation," Nikolas Tombazis said as per BBC Sport.

"We understand that his career is taking a new direction going forward and we support and respect his desire to pursue another path."

"I believe the organisation is on a firm footing in terms of technical expertise for the tasks which lie ahead - particularly the introduction of the 2026 regulations," he said.
