Absurd liability lawsuits, GA's addiction to 100LL and inability to evolve to use a lower cost highly available alternative, and outrageously expensive commercial insurance are all making it a big financial challenge for operators to offer affordable services, and that's what will limit new recreational flyers.
I've been sticking my neck out for a couple years now, trying to make it reasonably affordable for the average Joe to have a way to enjoy flying around here and most days I feel like the industry is against me.
Some of my ideas to reform GA:
1. Kill 100LL - adapt high volume alternatives like high octane autogas with simple tests or additives for volatility so hourly operating costs can be reduced
2. Seriously limit liability to manufacturers, FBO's, maintenance, Pilots, etc (only allow recovery of real costs or severly limited punitive damages) - this needs to happen throughout US industry. This will bring the need for and cost of insurance down drastically
3. Streamline and simplify TSO and FAA aircraft certification so new manufacturers can jump in the game, revitalize the field approval process, allowing and ecouraging field workers to use common sense
4. Groups like AOPA, NAFI, SAFE, etc should explore collective/group purchasing for commercial operators insurance
