Aviation Accident Summary CHI04LA001

Shenandoah, IA, USA

Aircraft #1

N3772D

Cessna 182A

Analysis

The airplane sustained substantial damage when it impacted a ditch during an emergency landing following a loss of engine power. The pilot reported that the engine "popped" twice and the airplane lost engine power. The pilot attempted to restart the engine but was unsuccessful. The pilot-rated passenger prepared for an emergency landing at the destination airport. They realized the airplane would land short of the airport and prepared to "ditch." The airplane touched down in a cornfield and subsequently impacted a ditch. An FAA inspector examined the airplane subsequent to the accident and found five gallons of fuel in the left tank. The fuel tank strainer and fittings were pulled from the right wing. The strainer was destroyed, but had no signs of blockage previous to the accident. No fuel was observed in the right tank or in the fuel inlet line of the carburetor. The airframe and engine were examined and no anomalies were found.

Factual Information

On October 2, 2003, at 2100 central daylight time, a Cessna 182A, N3772D, piloted by a commercial pilot, sustained substantial damage when it impacted terrain during a forced landing following a loss of engine power near Shenandoah Municipal Airport (SDA), Shenandoah, Iowa. Visual meteorological conditions prevailed at the time of the accident. The flight was operating under the provisions of 14 CFR Part 91 without a flight plan. The commercial pilot reported minor injuries. The pilot-rated passenger reported serious injuries. The flight departed Coles County Memorial Airport (MTO), near Mattoon, Illinois, at 1820. According to the pilot's written statement, during cruise flight at 6,500 feet mean sea level, the engine "popped" twice and lost engine power. The pilot stated he tried to restart the engine several times. He reported he "went through the flow checks and restart procedures all the way until impact never admitting to ourselves that the engine was not going to restart." The pilot stated the pilot-rated passenger had SDA in sight and tried to make an emergency landing at the airport. The pilot reported they realized they "were not going to make the airport about a quarter mile out and prepared to ditch." The pilot reported they touched down in a cornfield and subsequently impacted a ditch. The pilot stated that the nose, nose gear, and right wing were separated from the airplane. The pilot also stated there was substantial damage to the cockpit, dash and windshield. A Federal Aviation Administration (FAA) inspector examined the airplane subsequent to the accident. The inspector reported the right wing was separated from the aft attach point, but not completely detached from the airplane. Approximately five gallons of fuel was strained from the left tank. The fuel tank strainer and fittings were pulled from the right wing. The strainer was destroyed, but had no signs of blockage previous to the accident. No fuel was observed in the right tank or in the fuel inlet line of the carburetor. The fuel selector was on the left tank. The airframe and engine were examined and no preexisting anomalies were found.

Probable Cause and Findings

Loss of engine power for an undetermined reason during cruise and the unsuitable terrain for landing encountered by the pilot. The factors to the accident were the dark night, the corn crop, and the ditch.
