Narrative:
A Gates Learjet 24A, N805NA, made a hard landing at Victorville Airport, California. The National Aeronautics and Space Administration (NASA) was operating the airplane as a public-use flight. The local training flight departed Edwards Air Force Base, California, about 10:55.
After completing local air work, the flight proceeded to Victorville to practice touch-and-go landings. The pilot made the first touch-and-go. The copilot successfully made the second touch-and-go. The copilot attempted the third touch-and-go. At 50 feet, he disengaged the yaw damper and entered a pilot induced lateral oscillation. The airplane rapidly decelerated and developed a high sink rate. The airplane dragged the right wing tip fuel tank, which separated from the airplane, and the airplane bounced back into the air. The airplane landed hard, the main landing gear collapsed, and the airplane skidded to a stop off the right side of the runway. Both pilots and the passenger deplaned through the main entry door. The pilot-in-command stated that he had not demonstrated the handling characteristics of the airplane with the yaw damper off. He felt he did not react quickly enough to prevent the accident.

Probable Cause:

PROBABLE CAUSE: "The copilot inadvertently induced a lateral oscillation resulting in an in-flight loss of control. The pilot-in-command failed to adequately surpervise the copilot."
