I worked for a company in southern Africa (five or so years ago) that operated C208s. The two brand-new ones that we received were in excellent condition, as one would expect. But on the first maintenance check of one, I found a countersinking tool lying against a frame in the rear fuselage, just aft of the flying control pulleys. A good addition to my toolbox but it could have proved worse...
Not a good advertisement for Cessna's quality control final inspection. No gripes otherwise, maintenance-wise.
