Aviation Accident Summary CHI04LA008

Harvard, IL, USA

Aircraft #1

N3848H

Ercoupe (Eng & Research Corp.) 415-D

Analysis

The airplane contacted a corn crop while attempting to land on an unlit grass airstrip at night. The pilot stated that he was making a low approach over the unlit airstrip to determine if he was able to see it well enough to land. He stated that if he was unable to see well enough, he had planned to fly to a nearby airport. He stated the field elevation at the airstrip is 1,000 feet and he set his altimeter after listening to the Automated Terminal Information Service (ATIS) of a airport which was approximately 28 statue miles away. He stated that once on final approach, he was able to see the lights from the open hangar at the far end of the airstrip. He reported he descended in the general direction of the runway threshold using a flashlight in the cockpit to view the altimeter. The pilot reported he was next aware of the sound of corn stalks hitting the airplane. The airplane then impacted the ground and turned to the right with the nose gear collapsing. The airplane contacted the corn stalks approximately two-tenths of a mile from the end of the runway. The pilot reported, "I would say I failed to monitor the rate of sink for the fly-by/approach and the situation was due to pilot error."

Factual Information

On October 9, 2003, at 1945 central daylight time, an Ercoupe 415-D, N3848H, operated by a private pilot, collided with a corn crop while attempting to land on runway 18 at a private airstrip (2,650 feet by 120 feet, grass) in Harvard, Illinois. The pilot was not injured. The airplane was substantially damaged. The 14 CFR Part 91 personal flight was operating in visual meteorological conditions without a flight plan. The flight originated from Palwaukee Municipal Airport (PWK), Wheeling, Illinois, at 1900. The pilot stated that he was making a low approach over the unlit airstrip to determine if he was able to see it well enough to land. He stated that if he was unable to see well enough, he had planned to fly to nearby Dacy Airport (0C0). He stated the field elevation at the airstrip is 1,000 feet. The pilot reported that he set his altimeter after listening to the Greater Rockford Airport (RFD) Automated Terminal Information Service (ATIS). RFD is located approximately 28 statue miles from the accident site. He stated that once on final approach, he was able to see the lights from the open hangar at the far end of the airstrip. He reported he descended in the general direction of the runway threshold using a flashlight in the cockpit to view the altimeter. The pilot reported he was next aware of the sound of corn stalks hitting the airplane. The airplane then impacted the ground and turned to the right with the nose gear collapsing. The airplane contacted the corn stalks approximately two-tenths of a mile from the end of the runway. The pilot reported, "I would say I failed to monitor the rate of sink for the fly-by/approach and the situation was due to pilot error."

Probable Cause and Findings

The pilot misjudged his altitude and distance from the approach end of the airstrip, along with his decision to land at an unlit airstrip at night. Factors involved in the accident were the the night lighting conditions, the unlit airstrip, and the corn crop which the airplane contacted.
