A Mokulele Airlines flight from Maui to the Big Island was forced to turn around and make an emergency landing after engine failure.

Hawaii News Now reports that the plane glided back to the Kahului airport after the propeller on the single-engine plane stopped turning. The plane landed without incident at 9:35 a.m. Wednesday.

The Federal Aviation Administration is investigating.

A passenger on the flight who uses Mokulele to make the trip regularly, said he could hear the engine malfunctioning. Emergency personnel were on the ground when they landed, but no one was hurt.
