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. Earlier, at 13:26, the flight had received a weather observation which reported an indefinite 1,400-foot ceiling, overcast, lower broken clouds, visibility of 3 miles, rain, wind southeast at 28 miles per hour, with gusts to 40 miles per hour. The flight had commenced the let down but at 13:43 it advised Annette Radio that it was proceeding to Juneau because of extreme turbulence. 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.
