It is not clear from the information provided the full circumstances that lead to your father's death. Although you have mentioned that death occurred as a result of a 'light' a/c accident, was he a passenger or pilot; was the flight being undertaken for commercial air transport, leisure, training etc. Did the accident occur in the UK? Has the AAIB published a report? Has an Inquest been held,or are criminal proceedings in contemplation? Terms of insurance contract etc There is thus a question of liability (Culpabilty) and without knowing that sort of information it is difficult to get any considered views. For what it is worth, my dealings with aviation insurers has been positive (3 aircraft losses and 1 a/c loss with fatality) Death or injury in a/c accidents are not significantly more difficult to litigate than in other circumstances, but please get a good solicitor to review and advise. It should not be that expensive.
