Fatal Spin Accident Involving Moravan Z-42 M Near Frankenförde

Casualties unknown • nahe Frankenförde, DE

A private flight involving a Moravan Z-42 M ended in a fatal spin accident near Frankenförde, Germany, resulting in the deaths of both occupants.

What happened

On May 17, 1997, a Moravan Z-42 M aircraft departed from Schönhagen airfield for a private flight. The aircraft was occupied by the pilot and a flight instructor acting as a passenger. At approximately 14:15, witnesses near Frankenförde observed the aircraft performing several spiral-like maneuvers accompanied by a rapid loss of altitude. The aircraft eventually disappeared behind a treeline. Later that evening, the wreckage was located in a former maneuver area.

The investigation

The BFU investigation examined the wreckage and the flight path. The aircraft struck the ground on its landing gear, with the propeller spinner and the underside of the engine making contact with the terrain. The investigation found that the engine was at a standstill upon impact. While the fuel selector lever was found in the closed position, the connection linkage had been broken during the impact, making it impossible to definitively determine the valve's position prior to the crash. However, the investigators ruled out fuel exhaustion due to the short duration of the flight.

Physical evidence at the scene, including the lack of a forward sliding track and the observed flight patterns, suggested the aircraft was in a spin that could not be recovered from. The investigation also addressed initial toxicology reports that suggested high blood alcohol levels; however, a specialized medical expert concluded that these levels were the result of post-mortem decomposition in high temperatures and that both occupants were sober at the time of the accident.

Findings

  • The aircraft was not authorized for aerobatic flight or intentional spinning at the time of the accident due to airworthiness limitations regarding fatigue.
  • The aircraft was within its permissible weight and center of gravity limits.
  • No mechanical defects were found in the control surfaces or the engine mechanics.
  • The occupants suffered fatal injuries due to the high-impact forces and the severe deformation of the cabin, which also trapped them within the wreckage.
  • The investigation could not determine the specific reason why the aircraft entered the stalled condition or why the pilot was unable to recover from the spin.

Probable cause

The accident was caused by the aircraft entering an excessive flight attitude resulting in a spin at an altitude of approximately 1,000 meters, which was not recovered from in time.
