GROVER HILL, Ohio (AP) – Officials in northwest Ohio are investigating a small plane crash believed to have been fatal for all on board. 

The Blade newspaper in Toledo reports the Paulding County Sheriff's office confirmed that a crash involving a single-engine plane occurred around 6 p.m.  Thursday in an open field near Grover Hill in Paulding County. 

A Federal Aviation Administration spokeswoman says the plane was on approach to land about 23 miles away in Findlay. 

The National Transportation Safety Board tells WOWO News that a preliminary report says the plane took off from the Washington Municipal Airport located in the city of Washington, Iowa and was headed to the Findlay Airport.  

Witnesses reported flames visible from the plane before it crashed in the field. The sheriff's office says 911 callers reported a possible explosion. 

Authorities said no one was transported to hospitals for injuries. The number of people on board was not immediately released, and the county coroner had been called. 

Officials are still investigating the crash.
