NTSB investigators may not have traveled in support of this investigation and used data provided by various sources to prepare this aircraft accident report.

The experimental amateur-built airplane had been airborne for approximately 30 minutes on its inaugural flight when the engine stopped producing power. The pilot subsequently performed a forced landing to a field, and during the landing the main landing gear separated from the fuselage, causing the fuselage to wrinkle and bend. Postaccident examination of the engine's electronic ignition module revealed that it was partially melted. The electronic module had been mounted approximately 5 inches from the engine's exhaust pipe due to lack of clearance between the top of the engine and its cowling. The installation manual for the module states that the maximum ambient temperature for the electronic module is 175 degrees Fahrenheit.

The National Transportation Safety Board determines the probable cause(s) of this accident to be:

A loss of engine power during approach due to thermal damage to the engine's electronic ignition module. Contributing to the accident was the builder’s placement of the ignition module near the engine’s exhaust.
