Alon A2 N5607F accident near Holland, Michigan

Probable cause

A total loss of engine power due to fuel starvation during cruise flight. Contributing to the accident was the pilot’s inadequate preflight fuel planning.

NTSB analysis

The pilot reported that he visually checked the airplane's fuel tanks before departure but that he did not measure the amount of fuel. He added that the fuel flow meter showed that the airplane had 9.7 gallons of fuel at takeoff. After takeoff, the pilot flew to a city about 70 miles away, took some photographs over another city, and then conducted a touch-and-go at another airport. Shortly after, he turned the airplane north, and, about 30 seconds later, the engine lost power and then "quit." During the subsequent forced landing on a beach, the engine sustained damage, and the fuselage and right wing spar sustained substantial damage.

An on-scene examination of the wreckage revealed no apparent fuel spills, leaks, or stains nor were any found in the hangar after the airplane was recovered. Due to the damage, the engine could not be test run. When examined, the gascolator was found nearly filled with fuel; the total recovered fuel on board was estimated to be about 1/2 gallon. It is likely that most of the fuel was used during the flight and that the small amount of fuel remaining was not sufficient to reach the engine while the airplane was turning, which led to the engine losing power. Given the lack of fuel, the pilot likely did not conduct adequate preflight fuel planning to ensure that there was sufficient fuel for the flight and that required reserves (30 minutes) for visual flight rules flight remained.
