100 Hours total time - it's an insurance thing albeit an illogical one.
So a PPL at 50 hour person cannot fly it with 40 hours post PPL whereas a 95 hour PPL with six hours post PPL can.
They use to not have that stipulation so we could do initial training on it too - the normal US insurers do not cover airplanes here so mine is insured with a syndicate direct out of Lloyds, so they have lots of 747's Airbusses and the like and my PA28 - I only got it because my professional indemnity insurance broker has a contact with them. It costs a fortune but is iron clad - other get it much, much cheaper but using accommodation addresses in the us, works fine for ramp checks but not so sure in the event of an accident.
