NTSB Identification: CEN13LA116
14 CFR Part 91: General Aviation
Accident occurred Monday, December 24, 2012 in San Antonio, TX
Probable Cause Approval Date: 12/11/2013
Aircraft: Seguine Swift II, registration: N84NS
Injuries: 1 Serious,1 Minor.

NTSB investigators may not have traveled in support of this investigation and used data provided by various sources to prepare this aircraft accident report.

The airplane was climbing through about 50 to 75 feet above ground level when it suddenly rolled left. The pilot tried to counteract the roll, but the airplane was unresponsive to control inputs. The sudden roll followed by a lack of control authority was consistent with an aerodynamic stall as the airplane transitioned from the aerodynamic effects of flight near the ground. A stall progression near the ailerons would have affected control authority. A postaccident examination of the flight control system revealed no malfunctions or failures that would have precluded normal operation. It is likely that the pilot climbed too steeply after takeoff without attaining the proper airspeed.

The National Transportation Safety Board determines the probable cause(s) of this accident to be:

The pilot's failure to attain a proper pitch attitude and airspeed during initial climb, which resulted in an aerodynamic stall.
