MILAN — The Italian Air Force said it was investigating whether an aircraft of its acrobatic team struck birds before it crashed near an airport, killing a child on the ground.

A 5-year-old girl and her family were traveling in a car near the perimeter of the airport near the northern city of Turin when the aircraft crashed Saturday afternoon, bursting into flames and smashing through the airport fence.

The girl’s mother and older brother remained hospitalized for treatment of burns while the father was released Sunday, hospital officials said.

In 1988, three aircraft of the Frecce Tricolori squadron collided and crashed to the ground during an air show at Ramstein Air Base in Germany attended by around 300,000 people. The three pilots and 67 people on the ground died. Hundreds more suffered injuries.

The Frecce Tricolori are based at Rivolto, an Italian base about 40 minutes east of Aviano Air Base. The Italian jets perform every year over Aviano, drawing hundreds of American and Italian onlookers.

Video of the crash shows nine aircraft in two tight V-formations, before one of the aircraft drops below the others and crashes, sending a fireball into the air. In the video, the pilot —identified as Maj. Oscar Del Do — can be seen ejecting with a parachute shortly before impact inside a fence airfield. He suffered burns.

The Air Force said the reason for the crash was under investigation, but said one hypothesis was that the aircraft suffered a bird strike during takeoff. Italian prosecutors were also investigating.

Frecce Tricolori, Italy’s premier team of acrobatic pilots, was preparing for an air show scheduled for Sunday as part of events marking the 100th anniversary of the Italian Air Force.

They typically perform dramatic fly-bys at events of national importance, leaving streaks of red, green and white smoke, the colors of the Italian flag. They perform intricate acrobatics during air shows.
