What happened
On April 23, 2008, a Piper PA-46-350P, registration D-EPOE, was conducting a flight revalidation maneuver near Parma Airport. The flight, which included the pilot, a flight examiner, and one passenger, was performing a simulated engine failure procedure. After completing a left-hand pattern, the pilot informed Parma Tower of his intention to perform a second simulation involving a right-hand pattern.
During the execution of the maneuver, the aircraft entered a descent toward the area of Baganz and struck high-voltage power lines. The impact severed an electrical conductor and damaged others before the aircraft struck the ground near a roadway roundabout. The impact resulted in three fatalities and the total destruction of the aircraft.
The investigation
The ANSV investigation examined the flight path, the aircraft's mechanical condition, and the environmental factors present at the time of the accident. Investigators analyzed radio communications between the crew and Parma Tower, which remained regular until contact was lost. The investigation also included an examination of the wreckage and the propeller, which showed damage consistent with striking a metallic cable.
Medical examinations and autopsies were conducted on all three occupants. The results ruled out any pathological factors or the presence of toxins that could have impaired the crew's ability to fly. Additionally, the investigation confirmed that the engine was functioning at the time of impact, though not at full power.
Findings
- The aircraft struck an electrical line consisting of six conductors and a guard wire.
- The pilot likely experienced a loss of situational awareness due to the low position of the sun, which caused glare on the windshield and focused the pilot's attention on the side of the turn rather than the flight instruments.
- A reduction in airspeed, likely occurring during the transition from a left-hand turn to a right-hand turn, led to an aerodynamic stall.
- The low altitude at the time of the stall prevented the pilot from recovering control of the aircraft before the collision with the power lines and the subsequent ground impact.
