Narrative:
Four landing gear parts were sent for x-ray and magniflux inspection. The parts were rtned and during the receiving process, the x-ray report was misread. The component was tagged inadvertently as serviceable instead of rejected. There were four landing go around components sent for x-ray and magniflux. The magniflux report indicated all components passed inspection, the x-ray report indicated two of the landing gears failed inspection. During taxing for departure, the main gear collapsed damaging the aircraft float and hull. Passengers and baggage were removed. The flight was cancelled and the aircraft was up righted and taken to maintenance for repairs.
