OICs always had a 'duty of care' prior to MAA - so nothing has changed. The RAF Sports Board reccomended that Clubs become Ltd companies under Charity Commission rules - that way the individual is offered some protection, unless found negigent by the Coroner!
There's no DH rubbish going on as the airworthiness and trg is strictly CAA territory. Otherwise it would be a bit like the RAF insisting you had an FMT600 to drive your own car!
