A preliminary report by the National Transportation Safety Board blames a Jabara Airport employee for improperly fueling a Cessna plane, causing an emergency landing in January.
The report said the employee put jet fuel in the twin engine plane instead of the 100 low-lead fuel in the plane requires.
The pilot reported at about 3,000 feet the plane lost power. That's when he made an emergency landing in a Sedgwick County field. The pilot and his 2 passengers were injured.
Dr. David Koert at Wichita State University said he's surprised the mistake was made.
"Unless it's a pretty old aircraft, those tanks are supposed to prevent that exact mistake," Koert said. "It's a larger diameter nozzle so you shouldn't be able to put it in."
Jabara and the Wichita Airport Authority declined to comment.
