NTSB narrative
During an approach to runway 20, the airplane collided with a semi-tractor trailer that was traveling west on highway 136 near the overrun at the approach end of the runway. During impact, the airplane struck the truck's sleeper compartment and a backhoe on the truck's trailer. An eyewitness said that the airplane made its approach too low to the highway. The runway overrun area was approximately 60 feet from the highway. Flight control continuity was confirmed. A check of the engine, engine controls, and all other airplane systems revealed no anomaly.
Probable cause
the pilot misjudged distance/altitude to the runway, while on final approach to land, allowing the airplane to get too low and collide with a truck. A related factor was: the proximity of the truck (and highway) to the runway.

- 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. 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.
