NTSB narrative
The experimental amateur-built airplane impacted trees and terrain during a forced landing following a loss of engine power during takeoff. The private pilot was attempting his third flight test after obtaining a Special Airworthiness Certificate for the airplane. The engine had a history of oil temperature and oil pressure problems that the owner was attempting to fix. After departure, the pilot radioed tower personnel that he had an engine problem and was going to attempt to land on the highway. A post crash fire consumed the airplane. No maintenance records for the airplane were found, no records for the pilot were provided, and the cause of the engine problem could not be determined.
Probable cause
the loss of engine power during takeoff for undetermined reasons.

- Unreviewed is an editorial label, not an investigation status. API-sourced is not report-checked or human-reviewed. Explicit event totals are used without summing aircraft injury tables; onboard allocation is withheld. Unknown values remain unknown. The operation category is mapped from the NTSB-reported FAR part and has not been reviewed.
- Filled from the NTSB case API where the bulk record had no value: investigation status, coordinates. Values present in the bulk record are kept.
- The date is the local date, which is the same as the UTC date the NTSB stores.
