Future Club Training Gliders
In article Darryl Ramm writes:
Why would you cap a DG-1000 at a 3,000 hour life? There are already published 3000, 6000, 9000 (and every 1000 hours) inspections for the DG-1000. There are many high time ASK-21 around well beyond 3,000 hours. Many well used and patched up but still bright and shiny and modern looking. My bad. I was way too asleep when I wrote that. I found later that the service life of the ask-21 is 18,000 hours, apparently with similar inspections, where the DG claims 12,000 per another poster. In either case, the cost for that does go way down. OTOH the price quoted did was too low. No trailer, instruments, other options, etc. and I'm not sure a linear depreciation is the right model. Indeed, all true. I had forgotten about trailer/instruments/etc., stupidly assuming they were included. Linear depreciation is most likely wrong, too, though lots of cost/hour operation calculations seem to use i. I should have included insurance costs and other costs that are calculated into operating cost. For aircraft used for clubs and training, I would expect this to be a big item, and the order of magnitude higher price of the glider would have a large effect on the price of the annual insurance bill. But, I blew it big on the 3000 hours. Alan |
