Incident Overview
The pilot of a general aviation aircraft reported a loss of control during the landing approach. According to the pilot's statement, while the airplane was approximately 500 feet above ground level (AGL) and traveling at 81 knots, he "felt the descent rate increase significantly." In response, he increased engine power, but the high rate of descent continued. He then increased engine power further.
Loss of Control
Shortly after, a slow left roll developed. The pilot applied full right aileron and full right rudder to counteract the rolling motion. He also reduced engine power. The left roll subsequently stopped, and the pilot regained control of the aircraft. However, the airplane's heading had shifted approximately 45 degrees left of the runway heading.
Collision and Damage
The aircraft continued its flight path and impacted trees before striking terrain. The impact caused a fire to ignite. The pilot and a passenger exited the aircraft through the emergency exit. The airplane sustained substantial damage to the windscreens and fuselage.
Mechanical Findings
The pilot reported that there were no preaccident mechanical failures or malfunctions with the airplane that would have precluded normal operation.
