Edinburgh-based Flyglobespan has slammed a Sunday Times report accusing it of “endangering passenger safety” and said it has yet to receive a summons from the Civil Aviation Authority.

However, a Flyglobespan spokesman said the CAA charges involve “lesser technical matters”. The airline continues to operate as normal with CAA approval.

Flyglobespan faces three charges, having allegedly flown an aircraft across the Atlantic when its engine pressure gauges were unserviceable and then failed to file a safety report with the CAA.

The airline’s spokesman said: “We have not seen all the CAA documentation and, until we have fully studied it, we cannot comment in detail. However, we will vigorously contest any allegations we deem to be unjustified.”

He confirmed two senior managers have been replaced since the incident last October that led the CAA to suspend the carrier’s ETOPS licence – which allows operation of two-engine aircraft over large expanses of water.

The carrier flies transatlantic routes from Glasgow, Edinburgh, Gatwick, Manchester, Belfast and Bristol primarily to Canada but also to Orlando.
