The incident occurred during an operational flight destined for Serinyà. As the aircraft was on final approach to Banyoles, it struck another SB 2. The impact caused both planes to descend into the Lake of Banyoles. Emergency response teams located the wreckage in the water and managed to extract all personnel from the involved aircraft.

The primary event was a mid-air collision between two separate airframes during the approach phase. Despite the severity of the crash into a body of water, all three crew members were recovered alive. No specific mechanical failures or pilot error details are provided in the available records beyond the collision itself.
