What happened
The aircraft was returning to an unlighted private airstrip following a local pleasure flight. Although the sun had set, the pilot reported that the sky remained illuminated, providing some ambient light. The pilot successfully established an approach but stated that he lost sight of the runway once established on final approach.
In response, the pilot executed a low go-around in an attempt to visually reacquire the runway. He then elected to initiate a second approach. During this second attempt, the pilot again reported losing sight of the runway while on final. Deciding against a third landing attempt at the unlighted field, the pilot chose to perform another go-around and divert to a nearby airport equipped with lighting.
While initiating this second go-around maneuver, the aircraft struck a fence. The impact caused the aircraft to flip over onto its back.
