- In flight collision with terrain/water, descent - uncontrolled

## 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.
