Just days after Signature Aviation was acquired by a consortium of private equity firms including Blackstone, Global Infrastructure Partners, and Cascade Investments, company CEO Mark Johnstone was replaced by president and COO Tony Lefebvre, who moved into the position as interim CEO.
Johnstone had been with the company for more than 13 years, holding a variety of leadership roles, including EMEA managing director, group corporate development director, and global CFO, before taking the reins as CEO in January 2018.
Lefebvre, with a background in airline operations, joined the then BBA Aviation in 2013 as president and COO of its former ASIG commercial aviation services division. He was also responsible for the company’s since-divested global engine services operation as well as the Signature TECHNICAir maintenance division.
Signature operates the world’s largest network of FBOs, at more than 200 locations worldwide, between its owned facilities and those independent locations branded under its Signature Select affiliate program.
