Investigation Summary
The aircraft took off from Verona Villafranca Airport at 09:48 for a mission testing anti-aircraft radar systems. Approximately 34 minutes into the flight, the engine began experiencing technical difficulties near Ferrara. The pilot, Sub-lieutenant Bruno Viviani, initially considered landing at Ferrara, but determined the 600-meter runway was too short for the MB-326. He opted to divert to Bologna Airport, approximately 40 kilometers away. During the approach to Bologna, the situation deteriorated rapidly: Viviani reported a total engine failure, an on-board fire, and unresponsive flight controls. After attempting to steer the jet toward uninhabited fields, he ejected at 10:31. The aircraft continued in a pilotless glide for two minutes before striking the school building at 10:33. The impact created a seven-meter-wide hole in the school's wall and triggered a massive fuel-fed fire that trapped students and staff on the upper floors.
Final Conclusions
The investigation was conducted by the public prosecutor's office as Italy's aviation safety agency (ANSV) had not yet been established. The prosecution focused on the pilot's decision-making, arguing he should have steered toward the Adriatic Sea rather than a populated area like Bologna. In 1995, the pilot and two colonels were sentenced to 2.5 years in prison for involuntary manslaughter. However, the Court of Appeal overturned these convictions in 1997, ruling the defendants' actions were faultless and the crash was an inevitable tragedy resulting from a mechanical emergency. This acquittal was finalized by the Court of Cassation in 1998.

Safety Actions & Advisories
Establishment of ANSV
The lack of a dedicated civil aviation investigative body at the time of the crash contributed to the later establishment of the Agenzia Nazionale per la Sicurezza del Volo (ANSV) in 1999.

Acquittal of Officers
Reference ↗The 1997 acquittal of the pilot and his superiors was highly controversial among victims' families, who argued that directing a failing aircraft toward a city was a criminal act of negligence.
