What happened
Following a period of self-performed maintenance, an aircraft was undergoing its first flight since the completion of mechanical work. The maintenance tasks involved the removal, reinstallation, and rigging of the ailerons. As the aircraft transitioned into the initial climb phase immediately after lift-off, it entered an uncontrolled roll. The aircraft subsequently struck the terrain. There was one person on board, and the pilot sustained fatal injuries in the crash.
Findings
An investigation into the accident identified several critical errors regarding the aircraft's configuration and oversight. It was determined that the control linkages for the left aileron had been connected in reverse during the maintenance process. The findings also highlighted failures in the preflight inspection conducted by the pilot, as well as improper installation procedures and inadequate management of the maintenance tasks performed on the aircraft.
