Sequence of events

The events NTSB coded, in order, by phase of flight. The defining event is the one that best describes the accident. Under each, the cases with the same event anywhere in their sequence.

Analysis

The pilot reported that during the initial climb out, the engine experienced a partial loss of power which prompted his decision to return to the airport for a landing. While maneuvering to land at the airport, the engine completely stopped producing power. The airplane landed with the landing gear retracted in a wheat field near the runway. A postaccident examination of the airplane by a Federal Aviation Administration inspector revealed no evidence of preimpact anomalies with the airplane or the engine.

Factual narrative

On July 27, 2010, approximately 1000 central daylight time, a single-engine Beech F35, N3858B, owned and operated by a private individual, was substantially damaged during a gear up forced landing following a loss engine power near Enid, Oklahoma. The commercial pilot, the sole occupant, was not injured. Visual meteorological conditions prevailed and no flight plan was filed for the 14 Code of Federal Regulations Part 91 personal flight. The local flight had departed the Enid Woodring Municipal Airport (WDG), Enid, Oklahoma approximately 0950. According to the pilot, shortly after takeoff the airplane’s engine began to run rough. The pilot elected to return to WDG; however, prior to landing the engine experienced a total loss of power. With the gear in the retracted position, the pilot landed east of the runway in a wheat field. Pictures provided to the NTSB investigator-in-charge (IIC), revealed that the airplane’s fuselage sustained structural damage during the mishap. A Federal Aviation Administration (FAA) inspector examined the airplane following the accident. The inspector was not able to determine the reason for the loss of engine power.
