NTSB Identification: CEN11FA467
14 CFR Part 91: General Aviation
Accident occurred Saturday, July 09, 2011 in Scott, AR
Probable Cause Approval Date: 07/18/2013
Aircraft: RANS S-12, registration: N3266R
Injuries: 1 Fatal.

NTSB investigators either traveled in support of this investigation or conducted a significant amount of investigative work without any travel, and used data obtained from various sources to prepare this aircraft accident report.

According to data from a GPS receiver on board the airplane, the airplane made several turns just before it descended and impacted terrain. Examination of the wreckage and an engine run found no preimpact mechanical malfunctions or failures with the airframe or engine that would have precluded normal operation. The airplane’s ballistic recovery system was found deployed; however, damage and deployment signatures were consistent with activation due to ground impact. An autopsy conducted on the pilot found a complete obstruction of the left main coronary artery. While it was not possible to determine if the pilot was experiencing a heart attack in flight, it is possible that the pilot experienced acute arrhythmia or acute myocardial ischemia (decrease in blood flow), which would have led to the pilot’s loss of airplane control.

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

The pilot’s loss of airplane control, likely due to a cardiac event.
