Narrative:

Loss of engine power as well as all non-electric gauges/instruments. [Advised ATC]. Established best glide while turning back towards airport. Decided that gliding to ZZZ airport was not going to be possible so I selected a suitable field and prepared to land there. Landing was rough but uneventful and no passengers or crew were injured. Emergency services were notified.
