14 CFR Part 91: General Aviation
Accident occurred Thursday, November 29, 2012 in Blair, NE

Aircraft: ERCOUPE 415-C, registration: N720RC
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.

Witnesses reported seeing a low-flying airplane strike power lines near an auto dealership parking lot. There was a flash of light, and the airplane descended nose down into some parked trucks. When witnesses reached the airplane, the pilot was already deceased. However, none of the described injuries should have been immediately fatal. According to the autopsy report, the 92-year-old pilot’s death was attributed to severe coronary arteriosclerosis and atherosclerosis (quadruple vessel disease). Arteriosclerosis was noted throughout the main coronary arteries. The pilot most likely lost control of his airplane due to an acute coronary event related to his underlying severe coronary artery disease and that he was dead before the aircraft crashed. Federal Aviation Administration medical records, however, did not describe any coronary disease. The toxicology report did not find any medications associated with treated coronary disease. The pilot’s coronary disease likely was undiagnosed.

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

The pilot's loss of control due to physical incapacitation.
