Failure of the left main landing gear wheel lock nuts, which resulted in a wheel separation and nose over during landing.
The pilot’s failure to maintain directional control and adequate airspeed during takeoff which resulted in a collision with a river. Contributing to the accident was the pilot’s improper decision to load the airplane above its maximum allowable gross weight.
A total loss of engine power due to fuel starvation. Contributing to the accident was the pilot’s failure to accomplish a preflight inspection.
The pilot’s failure to maintain control of the airplane which resulted in an aerodynamic stall and impact with terrain.
The boat operator’s failure to remain a safe distance from the floatplane during the takeoff run, which resulted in a collision.
The pilot’s improper fuel planning and management, which resulted in a total loss of engine power due to fuel exhaustion.
The loss of control during landing due to the out of rig condition of the tailwheel, which resulted in a ground loop and impact with the runway.
The right seat pilot’s improper decision to perform a low approach with full flaps and the failure of the flaps to retract during the attempted go-around, which resulted in a forced landing.
The RV-8 pilot’s failure to account for the position of the RV-7 behind him during the landing roll in a staggered landing formation, which resulted in a ground collision of the two airplanes. Contributing to the accident was the self-induced pressure created by the air show environment to land, stop, and get off the runway into the grass as quickly as possible.
