Investigators believe a mechanical problem may have lead to a deadly plane crash last month in Edgefield County.
That November 25th crash killed the pilot, 56-year-old Richard Showalter, of Graniteville.
In a preliminary report, released Tuesday morning, the National Transportation Safety Board says some of the hardware that goes with the fuel shutoff valves was missing.
The report says the pilot visited a mechanic and was told to follow up, but never did.
