ST. JOSEPH, Mo. (AP) - A preliminary federal report shows that a fatal plane crash at a northwest Missouri air show occurred during a planned aerobatic maneuver.
The crash June 27 at the air show in Cameron killed the pilot, 50-year-old Steven O'Berg, from Smithville, Missouri. He was flying a Christen Industries Pitts S-2B used for stunts.
The St. Joseph News-Press reports (http://bit.ly/1HgcNDC) the National Transportation Safety Board says preliminary information shows the pilot planned to do 10 aerobatic maneuvers during the flight. O'Berg completed eight maneuvers, and crashed during the ninth.
The report doesn't detail the cause of the crash. It says the airplane pitched down and tumbled twice before entering a left spin and completing about two and a half revolutions before crashing.
The NTSB's full report will take about a year.
