How much would you discount an airplane's price, considering airframe age alone? Do not account for model, its condition, hours, panel, engine, paint, interior in any way. Just a rough average, across all lines of light singles, for airframe. Do you think it might be $500 per year? $5000 per year? ie two similar airplanes of similar attributes, one is 10 yrs older than the other. Considering airframe age alone.......$10K diff? $30K? Take your mind past minutiae for this, look at the big picture. Its so easy to get bogged down by 'it depends'. Be wild; shoot from the hip on this one. Use asking prices from ads if you find it helpful. Thanks.
