Flight 923 departed at 10:30 from Seattle for Juneau with an intermediate stop scheduled at Annette Island. Proceeding at 9,000 feet, the flight arrived over Annette Island at 13:38.

Just two minutes later the aircraft struck the north side of the Tamgas Mountain at an elevation of approximately 3,400 feet, 196 feet below the summit. The wreckage was found October 31.
