Mooney M20F N6467Q accident near North Elba, New York

Probable cause

The pilot’s failure to maintain adequate airspeed for the airplane’s configuration and flight profile, which resulted in an exceedance of the wing’s critical angle-of-attack and a subsequent aerodynamic stall/spin.

NTSB analysis

The accident airplane and another airplane approached the single runway from opposite directions. A witness reported hearing the pilot of the accident airplane reporting positions relative to the airport; he did not hear the pilot of the other airplane make any transmissions. Postaccident interviews with the pilot of the other airplane revealed that he was using a portable radio that likely became disabled due to its location and/or configuration in the cockpit; however, due to the type of airspace, neither airplane was required to have radio communications. As both airplanes approached the runway, both pilots saw the other airplane and successfully completed go-arounds to the right. The accident airplane then entered a steep climb, and, as it made a crosswind turn, the nose dropped, and the airplane entered a spin to the ground. Examination of the wreckage revealed that the landing gear were down and that the flaps were likely somewhat extended; however, the degree to which they were extended or whether they were in transit could not be determined. Wreckage damage indicated that the airplane was in a left spin at the time of impact. No preexisting mechanical anomalies were found that would have precluded normal operation.
