So ~$2000-$2500/month for a small (class 2) aircraft is a waste that messes the whole system..? eh?
Its relative, Sami : margins on small aircraft are slim enough : mx costs, relatively, are much higher : Unless you get a 'clean' uninterrupted lease on a small plane, down time adds up in terms of lost potential revenue : add parking fees and the actual time then required on lease-out to get to break-even gets increased further : but with that longer period comes added mx : my experience, you cant put a small plane with less than 2yrs to D-check or 3months to c-check on the market and hope for a sale ; so 'early' c/d checks become the norm, to try and keep it 'desirable' and thus get a longer-term lease from it : I'll be happy to be proved wrong, that this will not impact on small operators flying small planes ; just that I'm not going to be the one trying to prove that as my gut-instinct is that it will impact badly, in the longer term, and will undo all the good work done to make small aircraft workable in AWS. Part of the 'small plane' economics is having a second life for your ex-fleet planes in the market : either selling or leasing them out : lose that and re-fleeting becomes much longer term affair, needing you to maximise the 'operational' flying life of the aircraft, which rarely fits in with production line cycles : if, indeed, there will be a comparable type aircraft still around in production when you can economically re-fleet.
So, I do feel that now, looking to dispose of your ex-fleet small aircraft on the market will be a risky affair with potential long term costs disproportionate to its value : you may get lucky and move it one quickly, but, realistically, it makes more sense to cut your losses early and scrap it soon as you can : and there you go, fewer planes on the market, job done.
