Factual narrative

THE PLT STATED THAT A DOWNDRAFT WAS ENCOUNTERED AND AN UNDERSHOOT OCCURRED WHILE ON BASE LEG. A HIGH SINK RATE DEVELOPED AND THE PLT DID NOT TAKE CORRECTIVE ACTION SOON ENOUGH. THE ACFT STRUCK THE GROUND, ROLLED A SHORT DISTANCE THROUGH BUSHES, AND ACROSS A TWO FOOT GULLEY BEFORE COMING TO REST. THE PASSENGER STATED THAT THE PLT ENTERED INTO AN INTENTIONAL SPIN WHILE IN THE PRACTICE AREA IN ORDER TO SHOW OFF. HE ALSO STATED THAT THE PLT MADE A RATHER RAPID DESCENT BY THE USE OF SPOILERS THAT EXCEEDED THE LIMITS OF THE VERTICAL SPEED INDICATOR.
