Probable cause

The second pilot's misjudgement of altitude and distance from the runway which resulted in an undershoot, and the pilot-in-command's inadequate supervision in not taking timely corrective action. In addition, neither pilot had any experience in the airplane, and the second pilot had not flown during the previous 90 days.

Analysis

The second pilot had just rebuilt the experimental airplane. Having never flown this type of airplane, and having not flown in the last 90 days, he asked another pilot, who also did not have any time in type, to fly with him on the initial test flight as the pilot-in-command. After performing some airwork, the second pilot then flew the airplane to a nearby airport for a landing. The airplane landed short of the runway colliding with an 18-inch high gravel mound separating the right main gear.
