What happened
The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.
privacy data omitted Was demonstrating the aircraft to a potential buyer (privacy data omitted). They were north east of Parlin Airport doing various maneuvers, slow flight and then tried a simulated approach for landing (still northeast of Parlin). At approximately 1700 AGL they attempted a simulated go-around and applied full power, the engine stayed at idle power. It then started to run rough and eventually completely failed. They were still a few miles away from the airport and the only available landing site was interstate 89. They landed successfully in the northbound lane of the highway. There was no damage to the aircraft or any automobiles. No injuries.
The aircraft was moved off the road and a mechanic arrived to evaluate the cause, but found nothing. Over an hour later the engine was started and ran normally, (suspect carbuerator ice).the n. h. state police would not allow a takeoff from the highway, so in the interest of safety, the aircraft was disassembled and trucked to the airport.
