Incident Overview
Two Boeing A75 airplanes were engaged in formation practice for an upcoming air show. According to pre-arranged plans, the lead pilot initiated a right turn with a 20-degree bank. The trailing pilot was tasked with passing beneath the lead airplane's right side and then repositioning to the left side of the lead aircraft.
Sequence of Events
During the crossing maneuver, the trailing pilot lost visual contact with the lead airplane. As a result, the trailing pilot initiated an early pull-up. This action led to a collision between the trailing airplane and the underside of the lead airplane's left wing.
Aftermath
The collision occurred as the two aircraft made contact during the formation practice. The source does not specify any injuries, fatalities, or extent of damage beyond the described contact.
Probable Cause
The probable cause of the accident, as stated in the source, is that the trailing pilot lost sight of the lead airplane and pulled up prematurely, resulting in a collision with the lead aircraft's left wing.
