Student Pilot Killed in Diamond DA20 Crash into Tiber River

Casualties unknown • In prossimità Roma Urbe, IT

A flight training accident near Rome Urbe airport resulted in the death of a student pilot and serious injuries to the instructor after the aircraft stalled and plunged into the Tiber River.

What happened

On May 25, 2020, a Diamond DA20-C1, registration I-DADL, was conducting a routine flight training mission at Rome Urbe Airport (LIRU). The flight, operated by a flight school, involved an instructor and a student pilot performing circuit patterns and touch-and-go maneuvers.

Following the completion of a second circuit, the aircraft attempted a touch-and-go maneuver. During the subsequent climb, the aircraft entered a critical state and crashed into the Tiber River, where it sank to a depth of approximately 7 meters. The instructor managed to escape the wreckage and reach the riverbank with serious injuries, but the student pilot, who remained restrained in his seat, was killed.

The investigation

The ANSV investigation focused on the aircraft's performance and the crew's actions during the critical climb phase. Investigators examined the aircraft's engine performance, specifically looking at the availability of power and the configuration of the flaps. The investigation also reviewed the flight manual's emergency procedures for engine failure after takeoff and insufficient engine power.

Technical analysis of the wreckage and flight data suggested the aircraft impacted the water in a nose-low attitude with a high vertical velocity. Investigators also considered the environmental conditions, noting a 10-knot wind and a temperature of 27°C, as well as the instructor's physiological state following a long journey prior to the flight.

Probable cause

The accident was caused by a **loss of control in flight due to an aerodynamic stall** during a critical phase of flight characterized by low airspeed and low altitude. This stall was triggered by insufficient engine power—linked to a failure of the right magneto—and an incorrect flap configuration following the touch-and-go maneuver. The instructor's failure to follow emergency procedures for insufficient power and the lack of effective supervision of the student's technique during the crosswind landing contributed to the loss of control.
