UK-based regional carrier Aurigny Air has appointed Mark Darby as its interim chief executive following the departure of long-serving head Malcolm Hart.
The board of Aurigny is conducting a search to find a permanent successor to lead the airline, which has its headquarters near Guernsey Airport and is owned by the island of Guernsey.
Jon Moulton, chairman of the Aurigny Group, says: "It is with regret that I announce that Malcolm Hart has decided to step away from his involvement in Aurigny Air Services Limited to pursue other interests.
"Malcolm has been with us during a very challenging time for Aurigny and his experience, wisdom and hard work have been instrumental in our continued success in what is a very competitive market for all airlines."
Darby became a non-executive director at Aurigny in October 2011. He has extensive experience running regional carriers having previously been chief executive of Caribbean carrier Liat and latterly headed up Swiss carrier Flybaboo.
According to Flightglobal's Ascend Online Fleets database, Aurigny operates a fleet of three ATR-72s and six Britten Norman Trislanders on a network that covers several UK and French destinations. One of its main competitors is large UK regional Flybe.
