Probable cause

The pilot's failure to maintain adequate clearance from the lead airplane. A contributing factor was the pilot's inadequate visual lookout.

Analysis

The pilots of two Boeing A75 airplanes were practicing form ups for an air show. By pre-arrangement, the lead pilot entered a right 20 degree bank and began turning. The pilot who was in trail was supposed to pass beneath the lead airplane's right side and form up on the lead airplane's left side. During the crossing maneuver, the pilot of the trailing airplane lost sight of the lead airplane and pulled up prematurely, colliding with the bottom of the lead airplane's left wing.
