Aircraft Accident/Incident Report
Grain Valley, Missouri 64029

NTSB Narrative Summary Released at Completion of Accident
The parachute jump flight's airplane was at 3,700 feet MSL when the pilot cancelled the operation with the FAA approach controller without explanation. Witnesses observed the airplane trailing white and black smoke. One witness said he saw the airplane trailing black smoke with its engine making a banging sound. Three witnesses at the accident airport said the airplane had smoke and flames coming from the airplane's cowl and along the windshield as it approached the airport. They said the airplane banked right at a low altitude with its right wingtip striking the ground. The airplane caught fire during the collision sequence. The on-scene investigation revealed the engine, left side of the fuselage, bottom of left wing and its strut and the horizontal stabilizer and elevator were covered with oil film. The engine's oil filler tube was missing. The three filler tube mounting screws were not found at the accident site. Two of the 3 filler tube screw mounting holes had 2 of the screw threads next to the engine case's exterior surface pulled upward. The third screw hole threads were not pulled. The number 6 cylinder valve rocker arm cover had 5 of its 6 screws missing. The remaining screw was loose. The number 6 cylinder's bottom spark plug lead nut was disconnected. Its threads were not pulled. Examination of the engine revealed about 70 percent of the oil screen was covered by silver and bronze colored metallic debris. Holes were observed on the engine's left crankcase section near cylinders number 2 and 6. The engine's internal components suffered damage typical of oil loss and heat distress. The fracture face features on the engine's fractured left crankcase section were typical of overstress.
NTSB Probable Cause Narrative
Pilot's inadequate preflight, the partial loss of oil and the resulting rod failure. A factor was the pilot's failure to maintain flying speed.
