The crew was performing a flight from Italy to the UK, repatriating wounded soldiers and 7 crew members from the 550th Squadron.

A premature retraction of the landing gear during the takeoff roll caused the aircraft to crash on the runway. There were no casualties but the aircraft was damaged beyond repair.

Shortly after takeoff from Venosa AAF, while climbing, a life raft deployed accidentally in the cabin, went through the left door intentionally let opened and hit the port stabilizer. The captain ordered his crew to bail out and three of them were able to abandon the aircraft before it crashed in a field located 13 km northeast of Spinazzola, about 25 km east of Venosa.
