Incident Overview
During an approach to an airport, the pilot shut down the left engine to demonstrate a single-engine landing to a prospective new owner. After entering the base leg-to-final turn, the pilot-in-command (PIC) attempted to lower the landing gear, but it did not respond. He then realized that the hydraulic pump was driven by the left engine.
Restart Attempt
The pilot attempted to restart the left engine. Prior to doing so, he passed control of the aircraft to a commercially rated passenger who had no experience in that make and model. The passenger's attempt to restart the left engine was unsuccessful.
Pilot Takes Control
After taking control of the aircraft from the passenger, the pilot recognized that he had overshot the airport. He elected to land in a wheatfield. During the landing roll, the aircraft struck a fence.
Investigation
The investigation into the incident is ongoing. No further details have been released regarding the aircraft type, registration, or injuries.
