Events During Taxi and Takeoff
As the aircraft was taxiing for takeoff, witnesses observed that the left rear baggage door was unlocked and hanging down. A warning about the door was relayed to the pilot via the tower, but by that time the aircraft had already become airborne and the pilot had reported a control problem. During lift-off, the aircraft pitched up sharply and entered an immediate right bank of about 45 degrees. As the landing gear retracted, the bank angle decreased to approximately 20 degrees.
In-Flight Control Difficulties
The aircraft was reported to yaw slightly from side to side and circle to the right while climbing to about 1,000 feet. A witness who was in radio contact asked the pilot about the problem; the pilot replied that the controls were locked to one side. Following advice from others, the pilot attempted to control the aircraft using engine power adjustments, but the aircraft lost altitude to about 200 feet above ground level.
Collision and Crash
While maneuvering at low altitude, the aircraft struck a tree, then hit a utility pole, and subsequently crashed. During the impact, the lower fuselage, which housed the flight control linkages, was badly damaged. The pilot, who was the sole occupant, was killed.
Investigation Findings
No preimpact mechanical problem was verified concerning the flight controls, autopilot, or trim. A pilot who had previously flown the same aircraft with the baggage door open reported experiencing no adverse control problems. The official probable cause findings include:
Occurrence #1: Airframe/component/system failure/malfunction during takeoff initial climb
- Aircraft preflight improper (pilot in command)
- Door open
- Flight control system undetermined
Occurrence #2: Loss of control in flight (maneuvering phase)
Occurrence #3: In flight collision with object (tree, utility pole) during maneuvering
Occurrence #4: In flight collision with terrain (uncontrolled descent)
