Analysis
Plt had purchased the acft earlier on day of accident. He had no previous time in the acft. He flew for 220 miles and made first landing. Acft serviced with fuel only. Takeoff was made and he flew for 60 miles. Eng began to vibrate and black smoke observed. Plt made emerg landing and touched down hard in level sod field. Investigation revealed the #1 rod failed from overheat caused by lack of oil. Oil drain plug missing. Evidence of dirt in the hole threads. No evidence of impact on drain plug. Eng tear down and NTSB metallurgical exam confirmed oil starvation to rod bearing components. Last oil change was more than one month prior to the accident and the acft had not been flown until the day of the accident.
