About 1452 m.s.t., on November 16, 1979, Nevada Airlines, Inc., Flight 2504 crashed into a clearing in a heavily wooded area about 1.5 mi north of the departure end of runway 3 at Grand Canyon National Park Airport, Tusayan, Arizona. The aircraft crashed shortly after takeoff from runway 3. Of the 44 persons aboard, 10 were injured seriously. The aircraft was damaged substantially during the crash sequence and was destroyed by ground fire. The National Transportation Safety Board determines that the probable cause of the accident was the unwanted autofeather of the left propeller just after takeoff and an encounter with turbulence and downdrafts--a combination which exceeded the aircraft's single-engine climb capability which had been degraded by the high density-altitude and a turn to avoid an obstacle in the flightpath. Also, the available climb margin was reduced by the rising terrain along the flightpath. The cause(s) for the unwanted autofeather of the left propeller could not be determined.
