The NTSB's narrative final · quoted from the NTSB record
The pilot reported that, during takeoff, the airplane became airborne with 3,000 ft of runway remaining. When the airplane was between about 25 and 40 ft above ground level (agl), its nose dropped, and the pilot then pulled back on the control stick. The pilot was able to level out the airplane and establish a 200-ft-per-minute climb rate. As the airplane approached 75 ft agl at an indicated airspeed of about 95 mph, the airplane's nose dropped to about a 30- to 45-degree nose-down attitude. The pilot again pulled back on the control stick, but he was unable to regain control of the airplane before it impacted the ground. The pilot reported that the engine was running roughly during an initial start-up, but he stated that it ran normally during a subsequent start-up and two engine run-ups before taking off on the accident flight. A postaccident examination of the engine and airframe revealed no evidence of mechanical malfunctions or failures that would have precluded normal operation. The airplane's calculated gross weight exceeded its allowable maximum gross weight, and high-density altitude conditions existed at the time of the accident. Although these conditions likely affected the airplane's performance, the pilot was able to establish a positive climb rate after takeoff; however, he did not maintain control of the airplane as the pitch changed.
