The company went through repeated changes in ownership during the 1980s and 1990s. In 1985, Bristow Helicopters was acquired by British and Commonwealth Holdings plc. That same year, Alan Bristow stood down from his active role in managing the company. It was soon sold on as a component of the Bricom Group via a management buy-out in 1988. In July 1990, Bricom was acquired by Scandinavian investment company Rochfield. In 1991, Bristow Helicopters was subject to another management buy-out headed by managing director and chief executive Bryan Collins.
