Amateur-built 701 accident near Big Lake, Alaska, September 9, 2013
On September 9, 2013 at about 9:00 pm local time, a amateur-built 701, registered N701MG, was substantially damaged in an accident during maneuvering (low-alt flying) near Big Lake, Alaska. It was a personal flight under general aviation rules (Part 91). 1 person was killed and 1 person was seriously injured. The weather was visual conditions (good weather).
The NTSB's probable cause their words, unchanged
The pilot's failure to maintain adequate airspeed while maneuvering at a low altitude, which resulted in a stall and subsequent spin from which he could not recover.

The NTSB's narrative final · quoted from the NTSB record
The pilot departed a private runway and subsequently crashed in an area of sparsely populated dead spruce trees. The airplane collided with the ground in a left-wing, nose-low attitude, and impact damage was consistent with a near-vertical descent, indicating that an aerodynamic stall occurred. Postaccident examination of the airframe and engine and a test run of the engine revealed no mechanical malfunctions or anomalies that would have precluded normal operation. Given the lack of mechanical deficiencies with the airplane and engine and the airplane damage, it is likely that the pilot inadvertently stalled the airplane at a low altitude and was unable to recover.
