Preliminary information
On October 4, 2026, about 1822 mountain daylight time, a Lancair IV-P-T airplane, N5UC, was substantially damaged when it was involved in an accident near Ontario, Oregon. The pilot and passenger were not injured. The airplane was operated as a Title 14 Code of Federal Regulations Part 91 personal flight.
According to the pilot, the airplane departed Ontario Municipal Airport (ONO), Ontario, Oregon, destined for Provo Municipal Airport (PVU), Provo, Utah. During the initial climb, the airplane experienced a loss of engine power at an altitude of about 3,325 ft mean sea level. The pilot turned the airplane toward the departure airport, but then determined that he would be unable to reach the runway. He subsequently performed a forced landing in a field. While maneuvering to avoid a tree, the airplane’s left wing contacted the ground.
The airplane sustained substantial damage to the fuselage and left wing.
The wreckage was retained for further examination.
