Circumstances:
The commercial pilot departed on a planned 1-hour cargo cross-country flight in the autopilot-equipped airplane. About 3 minutes after departure, the controller instructed the pilot to fly direct to the destination airport at 2,000 ft mean sea level (msl). The pilot acknowledged the clearance, and there were no further radio transmissions from the airplane. The airplane continued flying past the destination airport in straight-and-level flight at 2,100 ft msl, consistent with the airplane operating under autopilot control, until it was about 100 miles beyond the destination airport. A witness near the accident site watched the airplane fly over at a low altitude, heard three "pops" come from the airplane, and then saw it bank to the left and begin to descend. The airplane continued in the descending left turn until he lost sight of it as it dropped below the horizon. The airplane impacted trees in about a 45° left bank and a level pitch attitude and came to rest in a heavily wooded area. The airplane sustained extensive thermal damage from a postcrash fire; however, examination of the remaining portions of the airframe, flight controls, engines, and engine accessories revealed no evidence of preimpact failure or malfunction. The fuel selector valves were found on the outboard tanks, which was in accordance with the normal cruise procedures in the pilot's operating handbook. Calculations based on the airplane's flight records and the fuel consumption information in the engine manual indicated that, at departure, the outboard tanks of the airplane contained sufficient fuel for about 1 hour 10 minutes of flight. The airplane had been flying for about 1 hour 15 minutes when the accident occurred. Therefore, it is likely that the fuel in the outboard tanks was exhausted; without pilot action to switch fuel tanks, the engines lost power as a result of fuel starvation, and the airplane descended and impacted trees and terrain. The overflight of the intended destination and the subsequent loss of engine power due to fuel starvation are indicative of pilot incapacitation. The pilot's autopsy identified no significant natural disease:however, the examination was limited by the severity of damage to the body. Further, there are a number of conditions, including cardiac arrhythmias, seizures, or other causes of loss of consciousness, that could incapacitate a pilot and leave no evidence at autopsy. The pilot's toxicology results indicated that the pilot had used marijuana/tetrahydrocannabinol (THC) at some point before the accident. THC can impair judgment, but it does not cause incapacitation; therefore, the circumstances of this accident are not consistent with impairment from THC, and, the pilot's THC use likely did not contribute to this accident. The reason for the pilot's incapacitation could not be determined.
Probable cause:
The pilot's incapacitation for unknown reasons, which resulted in an overflight of his destination, a subsequent loss of engine power due to fuel starvation, and collision with terrain.

Circumstances:
The pilot was tasked with a medical evacuation flight to take a patient from Port Hope Simpson to St. Anthony, Newfoundland and Labrador. The aircraft departed the company’s base of operations at Forteau, Newfoundland and Labrador, at approximately 0620 Newfoundland and Labrador daylight time. At approximately 0650, he made radio contact with the airfield attendant at the Port Hope Simpson Airport, advising that he was four nautical miles from the airport for landing. The weather in Port Hope Simpson was reported to be foggy. There were no further transmissions from the aircraft. Although the aircraft could not be seen, it could be heard west of the field. An application of power was heard, followed shortly thereafter by the sound of an impact. Once the fog cleared about 30 minutes later, smoke was visible in the hills approximately four nautical miles to the west of the Port Hope Simpson Airport. A ground search team was dispatched from Port Hope Simpson and the wreckage was found at approximately 1100. The sole occupant of the aircraft was fatally injured. The aircraft was destroyed by impact forces and a severe post-crash fire. There was no emergency locator transmitter signal.
Probable cause:
Finding as to Causes and Contributing Factors:
1. The aircraft departed controlled flight, likely in an aerodynamic stall, and impacted terrain for undetermined reasons.
Other Finding:
1. The lack of onboard recording devices prevented the investigation from determining the reasons why the aircraft departed controlled flight.
