Aviation Accident Summary WPR12LA055

Davis, CA, USA

Aircraft #1

N2466D

PIPER PA-38-112

Analysis

Before beginning the cross-country flight, the pilot did not fill the fuel tanks to capacity due to weight and balance concerns and estimated the amount of fuel onboard. While on final approach, the engine lost power. Following the loss of engine power, the pilot switched fuel tanks, but he could not recall which fuel tank the fuel selector was positioned to before the power loss. The pilot landed the airplane in a field short of the runway, and the airplane nosed over and came to rest inverted. When the airplane came to rest, the pilot positioned the fuel selector to the "off" position. Postaccident examination revealed that fuel was present in the left wing tank; however, no fuel was identified in the right wing tank. The engine was test run with no operational anomalies identified. Although the position of the fuel selector when the power loss occurred could not be determined, it is likely that it was positioned to the right fuel tank. In this position, the engine would have been unable to access fuel from the left fuel tank.

Factual Information

On December 6, 2011, at 1630 Pacific standard time, N2466D, a Piper PA 38-112, lost engine power during approach to Yolo County Airport, Davis, California. Mazzei Flying Service was operating the airplane under the provisions of Title 14 Code of Federal Regulations Part 91. The private pilot was not injured; the airplane sustained substantial damage. Visual meteorological conditions prevailed and no flight plan was filed. The pilot reported that he was conducting a cross-country flight in preparation for his commercial pilot certificate. The pilot reported departing with 26 gallons of fuel. He originally departed at 1415, conducted a touch-and-go landing at Sacramento International Airport, Sacramento, California, and was on the final approach leg to his second airport of intended landing when a loss of engine power occured. The pilot force-landed the airplane in a field and it nosed over. The airplane came to rest inverted. Initial responders reported that fuel seepage was present from the left wing tank and the exact fuel quantity in the tank at the time of the accident could not be determined. There was no fuel seepage from the right fuel tank. Residual fuel was found in each tank when the airplane was recovered the following morning. The engine was later test run. No operational anomalies were noted. In a conversation with the owner of the flight school, he reported that the pilot was unable to confirm how much fuel was in the airplane upon departure. Due to weight and balance requirements, the pilot had not filled the tanks to capacity and he estimated the amount of fuel onboard. He did not have a means of verifying the exact fuel quantity. Following the loss of engine power, the pilot switched fuel tanks, but could not recall to which fuel tank the fuel selector was positioned. When the airplane came to rest, the pilot positioned the fuel selector in the "Off" position.

Probable Cause and Findings

The pilot's inadequate fuel management, which resulted in a loss of engine power due to fuel starvation.
