Accident Summary
A Piper PA-28-235 collided with a dirt bank after experiencing a loss of power while on a night visual flight rules (VFR) pleasure flight. Approximately three minutes after takeoff, while cruising at 1,400 feet MSL, the engine RPM abruptly decreased to idle.
Fuel System Investigation
After the accident, the fuel selector control was found in the left tip tank position. The left tip tank was empty. The aircraft operator's manual states: "For all operations the tip tanks should be used last. When using less than the standard 84 gal capacity of the tanks, it is recommended the tip tanks be filled first and then regulate the fuel load by varying the amount of fuel in the inboard tanks."
Pilot Statement
The pilot indicated that approximately 30-35 gallons of fuel were on board at the last takeoff. The two main inboard tanks each have a capacity of 25 gallons, while each tip tank holds 17 gallons. The pilot further stated that during the preflight inspection, the left main tank was filled to the filler neck, while the right main tank was below the tab.
