Détails:
The flight departed from Anchorage at 00:20. At 02:38 the flight reported that it was over Yakataga, at 6,000 feet, and that it was proceeding in accordance with instrument flight rules to Yakutat, estimating arrival there at 03:20. Twenty-eight minutes later the flight called Yakutat Radio, stating that it was leaving the 6,000-foot altitude and making a straight in approach. The crew received Yakutat weather: Indefinite ceiling, 500-foot overcast visibility 3 miles, light drizzle, temperature and dew point 43 degrees, wind from the east-southeast at 10 miles per hour, altimeter setting 30.17. Yakutat Radio again called the flight at approximately 03:16, requesting that it report the height of the ceiling when it descended into the clear. Nothing more was heard from the flight. The DC-3 descended until the left wing struck a 140-foot spruce tree one mile distant and on a bearing of 70 degrees from the CAA Yakutat Radio station. The airplane crashed and caught fire.

Probable Cause:

PROBABLE CAUSE: "Failure to follow the approved instrument approach procedures while making an initial approach to Yakutat at an altitude insufficient to clear trees along the flight path."
