Flybe chief financial officer Philip de Klerk has resigned to take up the position of finance chief at performance materials manufacturer Low & Bonar.
In a statement on Tuesday (18 April), the struggling airline said de Klerk, who joined the company from SABMiller in August 2014, will remain as CFO of Flybe until 1 October.
"A process to appoint his successor has commenced," the company added.
"The Flybe Board wishes Philip well for the future and also thanks him for his major contribution over the last three years."
The Exeter-based airline will be issuing its 2016-17 full-year results on 8 June.
In an update last month, Flybe said it expects to slide into a loss having been hit by weak demand, strikes by airport staff in France, and lower air fares.
