NTSB summary

HISTORY OF FLIGHTOn July 24, 2021, about 1152 Pacific daylight time, a SIAI Marchetti SM-1019B, N28U, was substantially damaged when it was involved in an accident at Lewiston-Nez Perce County Airport (LWS), Lewiston, Idaho. The pilot was fatally injured. The airplane was operated as a Title 14 Code of Federal Regulations Part 91 personal flight. According to the pilot’s wife, the pilot planned to fly to Hungry Ridge Ranch Airport (37ID), Grangeville, Idaho, where he owned a residence.

The airplane pitched nose-up to about 45° while climbing to an altitude of about 80 ft above ground level, after which it rolled 90° to the left as the nose dropped. The airplane continued to roll left while descending and impacted the ground in a nose-down, left-wing-low attitude between runway 12 and taxiway C, about 970 ft beyond where the takeoff roll began. A postimpact fire ensued. Witnesses located at the airport described the airplane taking off normally before it aggressively pitched up and rolled left. PERSONNEL INFORMATIONThe pilot was a retired naval aviator, and current air show performer, with extensive flight experience in a broad range of aircraft. He held a commer

Probable cause

The pilot’s failure to remove the flight control lock before departure, which resulted in a loss of airplane control and impact with terrain. Contributing to the accident was his failure to perform an adequate preflight inspection and flight control check before takeoff.
