Confidence Rating: Accident investigation report completed and information captured
Narrative:
While on an ILS approach to runway 25, the aircraft suddenly descended below the glide slope and struck the ground nose wheel-first, 467 m short of the runway. It broke up and burst into flames.

While investigators officially concluded that the cause of the crash was undetermined, it has been argued based on a draft of the final report, that the copilot may have inadvertently trimmed the horizontal stabilizer to 0° on final approach.

PROBABLE CAUSE: "Owing to the high degree of destruction and total disintegration of the aircraft in the crash and ensuing fire it was not possible to establish the precise cause of the accident. The influence of unexpected atmospheric turbulence during the aircraft's final approach cannot be entirely ruled out."
