Hill’s FAA IR had lapsed, so had his UK IMC rating; his UK PPL was still valid. The aeroplane’s US registration had been cancelled three years previously; it was unregistered and stateless.
And effectively uninsured . I believe his estate was was sued and his family lost their home.
...he (Damon Hill) and his mother and two sisters were to discover that, because important documents had not been kept in order, the insurance policies were invalid. The consequences effectively ruined them...
It is for this reason amongst several others, that I believe the time is right for a far more transparent, clear, consistent and effectively policed compliance regime in all aspects of GA flying that involves the carriage of passengers. Period.
