Analysis

The pilot was cruising the airplane at 2,000 feet AGL when he noted a loss of oil pressure and increase in oil temperature. He also noted a loss in engine power. He elected to make a landing off airport and set up a pattern for the selected field. The airplane collided with trees and the ground during the landing approach. There were open and longer fields available adjacent to the selected field. The #1 piston was burned through and #5 piston showed overheat. The plt indicated he used 3100 RPM in cruise. The owner manual recommends 2400-2900 RPM at sea level and 2400-3050 RPM at 5000 ft. the ignition lead for a #1 cylinder spark plug did not have the proper connector.
