NTSB investigators used data provided by various sources and may not have traveled in support of this investigation to prepare this aircraft incident report.
During flight, one of the passengers (a single engine rated pilot) was seated in the right front seat. After arriving at the destination, the pilot initiated an ILS approach; however, before landing, a full deflection of the localizer CDI was noted, and the pilot executed a go-around. The pilot rated passenger stated that about 15 seconds later, the pilot released the control yoke, rested against his own seat back, and began to have convulsions. The pilot rated passenger began flying the airplane and advised ATC of the situation. The controller vectored the flight for landing, and the pilot rated passenger was initially unable to release the autopilot. At one point during the flight, the pilot's hand pulled the left engine mixture control to the idle cutoff position, but engine power was restored after the pilot rated passenger repositioned the mixture control. The pilot rated passenger landed the airplane; however, during the landing roll, he did not have access to the airplane's brake system. The airplane rolled off the left side of the runway onto grass, but was not damaged. Subsequently, the pilot was pronounced dead. After a post-mortem examination, the cause of death was listed as coronary atherosclerosis/hypertensive heart disease. According to the pilot's wife, he had no previous complaints suggestive of heart disease.
The National Transportation Safety Board determines the probable cause(s) of this incident to be: fatal incapacitation of the pilot due to a heart attack. Full narrative available
