According to the pilot's written statement, while on final approach for a straight in landing at his destination airport, the pilot had to apply right crosswind correction due to prevailing winds. He stated he "encountered a downdraft and picked up a decent rate." The pilot applied power but impacted short of the runway. The nose landing gear separated, the airplane nosed over, and then came to rest inverted. The airplane sustained substantial damage to the engine mounts and the right wing root and spar. The pilot reported no pre-impact mechanical malfunctions or anomalies that would have precluded normal operation.
