Narrative:
The SM-95B aircraft named “Ugolino Vivaldi” departed Paris at 10:16 for a flight to Rome. At 14:36 the crew reported over the Civitavecchia beacon at 6500 feet. A few minutes later, the aircraft was then seen descending in flames rapidly. The plane banked to the left heavily and crashed. The same aircraft on the same route with the same pilot on board had experienced a similar accident on 17 May 1949 near Lyon and had made a successful emergency landing at Lyon Airport with a two-meter right wing tip section missing.

Probable Cause:

PROBABLE CAUSE: “Fire in flight, due to lightning striking the wing frame of the aircraft and igniting a mixture of air and petrol fumes in one of the wing panels or fuel tanks.”
