On June 1, 1996, about 1415 eastern daylight time, a Cessna 172F, N8869U, was substantially damaged when it collided with trees and terrain during landing at Blairstown Airport(1N7), New Jersey. The private pilot and passenger were not injured. Visual meteorological conditions prevailed for the personal flight conducted under 14 CFR Part 91. No flight plan had been filed for the flight originating in Forty Fort, Pennsylvania. According to the NTSB Form 6120.1/2 the pilot stated that while landing on runway 25, "I experienced a wind shift from, essentially, up the runway to a direct crosswind to the right. This wind shift occurred during my landing flare, and blew me off centerline and toward the right side of the runway. I immediately took corrective action, but the inertia drove me off the edge of the runway onto the grass along side of runway 25. I continued to attempt corrective action, but because the trajectory of my travel was about 45 degrees along the runway, but on the grass, control was difficult to return. The roll started to straighten out gradually, but by this time, I was along the tree line and the right wing tip clipped a small tree, spinning the nose of the plane into the dirt embankment and trees, bringing the aircraft to a complete stop." The pilot reported no mechanical malfunctions.
