Chief executive Chris Woodroofe said the fault – first identified during the early hours of Sunday morning – had been traced to an underground cable, which caused a power surge, although he stressed a full investigation would take place.
Woodruffe added staff at the airport were working hard to minimise the impact of the outage on people’s travel plans over the coming days.
MAN said all flights scheduled for Monday (24 June) "were expected to run as usual", although passengers have been advised to check with their airline.
