I cant see a lot of "real" public transport opperations being effected by this as even runnung a Lycoming O-235 with a TBO of 2400+20%= 2880 this relates to 200 hours per year and I dont know how one could stay in business with that rate of use.
The people who it is going to hurt is the private owner who rents out his aircraft ocasionaly to help with the running costs.
Which probably accounts for quite a few aircraft around the country.
As all the costs increase every year, and as usage goes down and down, I think this may well be the final squeeze for some clubs.
Once again the CAA bites the (admittedly tiny) hand that feeds it. I think it has now been nibbled away to the shoulder.
