The preliminary report about a January plane crash that killed one person near Salem, South Dakota, is out.

The National Transportation Safety Board says the pilot told Sioux Falls Approach Control he was having chest pains and was blacking out. The plane ended up crashing in a field. The pilot was found about 100 feet from the plane.

Authorities are waiting on autopsy results to determine pilot Comet Haraldson’s cause of death.

While the preliminary report has been released on this plane crash, we are still waiting on a report for the Christmas Day plane crash that killed Sioux Falls philanthropists Vaughn and JoAnn Meyer. The NTSB says due to the backlog it could take a month to get that preliminary report.
