As a scene setter, our 8,000 hr, frequently used, immaculate and properly maintained AA5 never managed a Star Annual of less than several thou!! There was always something additional and unexpected to investigate, x-ray, fix, replace, etc, etc. If it wasn't the engine it was the prop, if it wasn't that it was COMM2, if it wasn't that the AI was on the way out, if it wasn't that the dorsal fin detached and we needed tyres, calipers, pads...
...you get the idea
But it was worth every penny
