Analysis

The aircraft had just successfully completed a series of practice approaches to a full stop. The training flight was being conducted to give refresher training to the pilot who had not flown a lear jet in over a year and had never flown a lear model 35. The flight instructor requested a practice approach with a missed approach and was cleared for the option. Witnesses stated that the aircraft rolled right and then rolled left to an inverted position. Colliding with the ground shortly thereafter.
