Piper PA-24-250 Comanche, N7682P: Accident occurred November 08, 2016 at Houlton International Airport (KHUL), Aroostook County, Maine

Aviation Accident Final Report - National Transportation Safety Board: https://app.ntsb.gov/pdf 

Analysis 

The private pilot had recently purchased the airplane; he and a flight instructor were conducting a local familiarization flight. After about 1 hour of flying with the left inboard fuel tank selected, he returned to the airport traffic pattern and performed two additional takeoffs. While on the left downwind leg of the traffic pattern, the engine experienced a total loss of power. The pilot checked that the fuel pump was on while the flight instructor attempted to determine why the engine lost power. The flight instructor then took control of the airplane and turned toward the runway. The airplane contacted the tops of some trees and landed on uneven terrain covered with tall grass and brush about 500 ft short of the runway, which resulted in substantial damage to the firewall, fuselage, and wings. Before exiting the airplane, the pilot moved the fuel selector to the "off" position.

A Federal Aviation Administration inspector examined the wreckage and found that the left inboard fuel tank was absent of fuel, while the right inboard fuel tank was full. The pilot reported no preimpact mechanical malfunctions or failures with the airplane that would have precluded normal operation. When asked how the accident could have been prevented, the pilot stated, "switched to the other fuel tank."

Probable Cause and Findings

The National Transportation Safety Board determines the probable cause(s) of this accident to be: 

A total loss of engine power due to fuel starvation, which resulted from the pilot's mismanagement of the available fuel.
