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 departed from a private airstrip for a local aerial application flight. Shortly after takeoff, the engine experienced a loss of power and the pilot elected to turn towards a field and perform a forced landing. During the landing, the airplane received major structural damage. A postaccident examination of the engine revealed that a cylinder on the radial engine was cracked, resulting in the loss of engine power. No other anomalies with the airplane were found. At the time this report was completed, the pilot had not submitted NTSB form 6120.1, Pilot/Operator Accident/Incident Report, as requested.
