NTSB summary
HISTORY OF FLIGHTOn July 1, 2017, about 0730 Pacific daylight time, a North Wing Scout XC light sport weight-shift-control (WSC) aircraft, N492XB, was destroyed when it impacted mountainous terrain while maneuvering near Chelan, Washington. The flight instructor and student pilot sustained fatal injuries. The aircraft was owned by the flight instructor who was operating it under the provisions of Title 14 Code of Federal Regulations Part 91. Visual meteorological conditions prevailed at the time of the accident, and no flight plan was filed for the local flight, which originated from Lake Chelan Airport (S10), Chelan, Washington, about 0630. A review of video obtained from an onboard camera revealed that, earlier that morning, the student pilot completed a checkride to obtain a sport pilot certificate. The instructor informed the student pilot that he completed the checkride successfully. They subsequently departed again and continued to fly in the local area. Video showed that the pilots stayed in the traffic pattern before departing to the east. As the aircraft continued to climb away from the airport, the pilots discussed finding an area with less turbulence. About 19 minutes after takeoff for the accident flight, the instructor took over the flight controls and began to demonstrate a spiral dive. As he entered the maneuver, the aircraft's bank angle increased, and the aircraft rotated nearly 360° with its nose pointing straight down. The video stopped recording upon impact. PERSONNEL INFORMATIONThe instructor, age 70, held a private pilot certificate with an airplane si
Probable cause
The flight instructor's failure to maintain control of the aircraft while demonstrating a spiral dive, which resulted in a loss of control. Contributing to the accident was the instructor's decision to demonstrate a spiral dive maneuver at an altitude that was too low for recovery.
