A flight from Venice to Florence ended in a fatal controlled flight into terrain accident due to poor visibility and mountainous terrain.

What happened

On May 3, 2002, a Robin DR 400-180R, registration D-EFOV, crashed in the municipality of Borgo San Lorenzo, Italy, resulting in two fatalities.

The aircraft departed from Venice San Nicolò under Visual Flight Rules (VFR), intending to land at Florence Peretola. At the time of the flight, a significant weather disturbance was affecting central Italy, bringing heavy thunderstorms, low clouds over the Apennine mountains, and the potential for icing.

During the flight, the pilot communicated with Pisa Approach, stating the aircraft was over Borgo San Lorenzo at 2,500 feet. Although initially denied landing at Florence due to procedural requirements and incoming IFR traffic, the pilot repeatedly requested landing permission due to deteriorating weather. After coordination between Pisa and Florence Tower, landing authorization was being processed. However, following a final transmission confirming the aircraft had reached the Santa Brigida waypoint, the pilot ceased all radio contact. The aircraft subsequently struck high trees and the terrain near the ridge between Monte Caldana and Monte Giovi.

The investigation

The ANSV investigation examined the flight history, meteorological conditions, and the technical state of the aircraft. Investigators analyzed radar tracks, radio transcripts, and wreckage distribution. The investigation also reviewed the pilot's qualifications and the aircraft's certification.

Evidence from a witness in the area suggested that visibility at ground level near the impact site was as low as 500 meters, significantly below the requirements for VFR flight. The wreckage analysis indicated that the impact was not caused by structural failure or engine loss of power, and there was no evidence of pilot incapacitation.

Probable cause

The cause of the accident was a **controlled flight into terrain (CFIT)**. Contributing factors included adverse meteorological conditions, the pilot's failure to adhere to VFR rules, insufficient knowledge of the local terrain, and the fact that neither the pilot nor the aircraft were certified for flight under Instrument Flight Rules (IFR) during the period of low visibility.
