Dick you need to take into account that you have a 48 month inspection due, which includes fuel tank inspections, detailed cockpit inspections, detailed wing inspection, detailed internal tail cone inspection and landing gear drag link and spring inspections. The 48 month inspection alone is 112 hours @ $110 = $12,300 which is quite reasonable. I would suggest you are not comparing apples with apples when you are looking at another aircraft's 12 month inspection costs.
