Narrative:On takeoff the pilot reported that the left canopy latch popped open. He verified that the right canopy latch was secure and radioed that he was returning to land. After turning an early crosswind and leveling his wings, the canopy came open in flight. The pilot made a mayday call, held the control stick full forward, and made a landing on a dirt road off the departure end of the runway. According to the aircraft manufacturer, if the aft hinged canopy opens in flight, a significant increase in drag occurs and controllability becomes marginal. An FAA inspector examined the aircraft's canopy after the accident. He could not identify any malfunctions with either of the canopy latches. He then functionally checked both of the corresponding latch closed micro switches and the enunciator light circuits, and found that they were working properly.
Probable Cause: The release of the aircraft's left canopy latch following takeoff resulting in the subsequent opening of the canopy in flight. The opened canopy resulted in a degradation of aircraft control and the subsequent hard landing.
