Didn't know there were any of those around the USA.Props for Dornier 328.
I had a trip to Piqua many years ago (took someone to visit Hartzell), and my scheduler was commenting on the identifier. He said, “I17 makes perfect sense…I for ohIo, and 17 because q is the 17th letter of the alphabet.” We looked at each other and started counting…sure enough, it is the 17th letter.They are Hartzell propellers, built in Piqua. Probably going to or from the repair shop there.
