Probably a starting point would be to reply to the regulator for an engineering order. Then approach your bank for a large loan, including the sale of your first born child as collateral. Then at a undetermined time in the future, measured in years you will run out of money and enthusiasm, and patience and decide it was not a good idea. You then become just another sacrifice to the great Gods of aviation who are put here to make life as difficult as possible for as many aviation business’s as possible.
