Narrative:
Aircraft engine involved had an accessory case replacement 2 days before incident. I performed the final inspection of the accessory case replacement and also returned engine to service. Engine was installed on aircraft in #1 position. On first flight after installation aircraft had a vibration and engine seized passing through FL250. Callback conversation with reporter revealed the following information: reporter states the log report was oil pressure and quantity went to zero and low oil pressure warning light illuminated. Had engine vibration then engine seized. Do not have any details on what failed internally to cause engine seizing. Reporter was not contacted by the FAA.
