NTSB narrative
The pilot reported that upon approaching his destination, air traffic control cleared him to descend to 3,000 feet and advised him of construction equipment on the airport. He reported he had the airport in sight and he closed his instrument flight plan. The pilot reported that shortly thereafter the right engine began to sputter and lose power. He stated that he saw the nearby highway with "no obstructions and some construction equipment" so he decided to land on the highway. The section of highway used for the landing was 3 miles northwest of the airport and it was closed due to road construction. The right wing tip tank contacted a construction road grader during the landing roll. The tip tank, wing ribs, and aileron were substantially damaged. Inspection of the airplane failed to reveal any mechanical failure/malfunction of the airplane or engine.
Probable cause
The pilot's poor in-flight planning to make an off airport precautionary landing and his failure to maintain clearance from the construction equipment during the landing roll. Contributing to the accident was the construction equipment.

- 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.
