Guernsey-based regional airline Aurigny is to be investigated after  one of its aircraft dropped below the minimum required height for flying in fog.

The passenger ATR72 aircraft was travelling from Southampton to Guernsey Airport on Monday 12 August during adverse weather conditions. The turboprop reached 56 feet above the island’s runway before its pilot aborted the landing.

French air safety authorities, Bureau d’Enquêtes et d’Analyses (BEA), have declared the event a “serious incident” based on data from UK authorities who are carrying out the inquiry. The aircraft is wet leased from Lithuanian company Jump Air.

The airline has been undergoing what has been described as a ‘period of disruption‘ as its summer schedule has been beset by delays and mistakes. Last month an ITV report said that a flight was forced to return to the UK mainland after having missed its Guernsey landing slot by just 90 seconds.  The airline is also facing a separate investigation after a DHC-8 overshot the runway in April.
