It is asking Dominic Lazrus, director of civil aviation for the Channel Islands, together with the UK’s Civil Aviation Authority, to look into the background of the flights involved in Mr Sala’s move from Nantes to Cardiff.
These flights carried Mr Sala, his agent, Cardiff City officials and others between the UK and France in December and January.
The 28-year-old Argentinian striker and pilot David Ibbotson died when the Piper Malibu aircraft they were travelling in came down north of Guernsey on 21 January.
Since the accident, questions have been raised over whether Mr Ibbotson had been flying in accordance with his licence, as private pilots cannot carry paying passengers.
This issue forms part of a wider investigation by the Air Accidents Investigation Branch.
Dave Edwards, the association’s chief executive, said that he understood that
seven flights in the weeks before the fatal crash were operated by a Guernsey firm on a non-commercial aircraft. ‘We represent the interests of licensed air carriers, charter brokers, airports and a wide range of other supporting organisations, and we are asking that the UK Civil Aviation Authority, together with the Guernsey office for the director of civil aviation, fully and transparently investigate the background to this series of flights,’ he said.
‘There’s enough circumstantial evidence here that would make us push the authorities to ensure no laws were broken and the safety of the travelling public was never compromised.’
The CAA said: ‘As there is an ongoing AAIB investigation into this accident, it would be inappropriate for us to comment at the moment. We will be assisting that investigation as required.’
