Probable cause
A loss of control in flight due to pilot incapacitation as a result of a heart attack.
Sequence of events
NTSB’s coding before 2008: each occurrence and phase of flight, and the causes and factors under it. The codes are defined in NTSB’s coding manual.
Analysis
The pilot was participating in a fly-by demonstration at the eaa convention. During initial climb, the airplane was observed to enter a steep bank to the left followed by a steep descent into the terrain. No mechanical anomalies with the airplane were found. Post-mortem examination of the pilot revealed atherosclerotic changes in the heart. The local coroner ruled that death was due to 'cardiac event followed by crash.'
