Aviation Accident Summary CEN19CA239

Oshkosh, WI, USA

Aircraft #1

N79575

Cessna 172

Analysis

The pilot was conducting the return leg of a cross-country flight. He reported that the airplane was full of fuel before he departed on the first leg of the trip, the duration of which he did not provide. The pilot also reported that he was concerned with the weather at his destination and did not add fuel before departing on the accident flight to expedite his return. He had planned the flight at 7,000 ft mean sea level and felt there was enough fuel onboard at that altitude. After about 1 hour of flight, an air traffic controller directed the pilot to climb to 9,000 ft and rerouted the flight. The pilot stated he became concerned with the fuel level at that time due to the climb and change in wind, but he chose to continue to his destination. About 30 minutes later and 20 miles short of the intended destination, the engine lost all power due to fuel exhaustion, and the pilot subsequently conducted an emergency landing in a field. At no time during the flight did the pilot express his concerns about the lack of fuel onboard to the controller, request a diversion to a closer airport, or declare an emergency. The elevator sustained substantial damage. The pilot reported that there were no preaccident mechanical failures or malfunctions with the airplane that would have precluded normal operation.

Factual Information

The pilot was conducting the return leg of a cross country flight when the engine lost power and the pilot subsequently performed an emergency landing in a field. The airplane elevator was substantially damaged during the landing. The pilot reported the airplane was full of fuel prior to departing on the first leg of the trip, the duration of which was not provided by the pilot. The pilot also reported he was concerned with the weather at his destination and did not add fuel prior to departing on the accident flight to expedite his return. He had planned the flight at 7k ft mean sea level and felt he had enough fuel onboard at that altitude. After about 1 hr of flight, air traffic control (ATC) directed him to climb to 9k ft and rerouted the flight. The pilot stated he became concerned with his fuel at that time due to the climb and change in wind, but elected to continue to his destination. The engine quit due to fuel exhaustion about 30 minutes later and 20 miles short of the intended destination. At no time during the flight did the pilot express his concerns about the lack of fuel onboard to ATC, request a diversion to a closer airport, or declare an emergency.

Probable Cause and Findings

The pilot's improper fuel planning and decision to not divert to a closer airport when the planned flight profile changed, which resulted in a total loss of engine power due to fuel exhaustion.
