From the Wikipedia article

An Ameriflight accident in February 1999 occurred on 12 February 1999. A Beechcraft C99 freighter of the cargo airline Ameriflight crashed during a flight from Tonopah Airport in Nevada to Eastern Sierra Regional Airport in California, killing the only pilot on board. The accident investigation attributed the accident to undisciplined and grossly negligent conduct by the pilot.

Accident sequence

The aircraft departed Tonopah at 09:30; the flight over the 73-mile route to Bishop was to be conducted under visual flight rules. The aircraft was not carrying any cargo at the time of the accident. The aircraft did not arrive at its destination.

Accident investigation

After the accident a search operation was launched and the wreckage was finally found on 14 February on the eastern slopes of White Mountain in the Inyo National Forest at an altitude of 9,500 feet.

A witness stated that they had observed the aircraft flying at an altitude of 7,000 to 8,000 feet as it flew into Trace Plumas Canyon on White Mountain and gradually turned to the left. The aircraft then disappeared from the witness's view. The canyon leads to the accident site. According to Ameriflight, the pilot was due to leave the company, as he had successfully applied for a position as captain of larger aircraft. The flight that day was to be his last along this route. Several acquaintances of the Tonopah-based pilot reported that he had intended to take a camera with him and photograph some scenic places along this route during the flight.

NTSB narrative

The airline transport pilot was repositioning the Beech C99 turboprop cargo hauler on a 73-mile trip without cargo. The pilot had been flying this route for some time and this was his last trip before upgrading to a larger aircraft and route. He told friends that he would take pictures of the scenic parts of the route on his last trip. Three witnesses reported seeing the airplane flying west at low altitude. Two of the witnesses were local ranchers who saw the airplane enter the White Mountains near Trace Plumas Canyon about 7,000 to 8,000 feet msl. White Mountain is 14,246 feet, tapering off north to 13,559 feet and south to 11,285 feet msl. The airplane was reported missing and 2 days later located on White Mountain about 9,400 feet msl. The company flight planned route is 15 miles south of the accident site through Westgard Pass, about 7,291 feet msl. Examination of the low energy impact and the subsequent recovery inspection failed to reveal any mechanical issues.

Probable cause

the pilot's failure to follow procedures and directives and his failure to maintain clearance from mountainous terrain.
