What happened
Shortly after departing, the aircraft was observed by witnesses performing a sudden, steep climb. This maneuver occurred while the plane was positioned beneath an 800-foot cloud ceiling. Following this sharp ascent, the aircraft entered an uncontrolled, nearly vertical descent. The flight ended when the plane impacted a river.
Findings
Investigations into the incident revealed that the pilot lacked both multi-engine and instrument ratings. While those familiar with the pilot, including a flight instructor, had expressed concerns regarding his flying proficiency, the pilot reportedly maintained high confidence in his own skills.
