Investigators from the Federal Aviation Administration are expected in Mankato Wednesday to try to determine why a small plane crashed Tuesday evening, injuring the pilot.

The crash happened about 8 p.m. Tuesday at the Mankato Regional Airport. Mankato Public Safety officials say the pilot was the only one on board when the plane crashed during a landing attempt.

Jeff Johnson, Director of Public Works said the plane came to rest in a field adjacent to the landing strip.

Authorities say the 78-year-old man has non-life threatening injuries. While the Mankato airport was closed, planes landed at surrounding airports including New Ulm and Waseca.

More details about the crash are pending an investigation from the Federal Aviation Administration and the National Transportation Safety Board.
