A technical fault followed by a pilot "inadvertently" pushing his foot on the brake led to a private plane, carrying one of the owners of Liverpool FC, leaving the runway, a report found.
Flights were cancelled at Liverpool John Lennon Airport after the private jet ended up on the grass in December 2019.
Mike Gordon, president of Fenway Sports Group, was on board. No-one was hurt.
The Air Accidents Investigation Branch (AAIB) said nose wheel steering failed.
Its report said the aircraft had then departed the right side of the runway after "directional control" was lost.
