SummaryCompanies Famin to replace Szafnauer as interim Alpine principalTop engineers Permane and Fry also leavingShakeup follows departure of Alpine CEO RossiFry moving to WilliamsSPA-FRANCORCHAMPS, Belgium, July 28 (Reuters) - Otmar Szafnauer will leave Renault-owned Alpine after Sunday's Belgian Grand Prix with Bruno Famin appointed interim principal on another day of upheaval that exposed rifts within the misfiring Formula One team. Alpine Academy director Julian Rouse was named as Permane's interim replacement while Matt Harman leads the technical team at Enstone. Rossi warned in May he would make changes if performances did not improve, and said the buck stopped with Szafnauer. Williams said Fry, who has had senior roles at both McLaren and Ferrari, will start work on Nov. 1. "His knowledge and experience will further strengthen the team's technical capabilities and pursuit of excellence as we build the next chapter of Williams," said principal James Vowles.
