Circumstances:
The commercial pilot was departing on a local post-maintenance test flight in the single-engine airplane; Four aileron cables had been replaced during the maintenance. Shortly after takeoff, the airplane began to roll right. As the climb progressed, the roll became more pronounced, and the airplane entered a spiraling dive. The pilot was able to maintain partial control after losing about 700 ft of altitude; he guided the airplane away from the airport and then gradually back for a landing approach. During this period, he reported to air traffic control personnel that the airplane had a "heavy right aileron." As the airplane passed over the runway threshold, it rolled right and crashed into a river adjacent to the runway. The aircraft was destroyed and both occupants were killed.
Probable cause:
The mechanic's incorrect installation of two aileron cables and the subsequent inadequate functional checks of the aileron system before flight by both the mechanic and the pilot, which prevented proper roll control from the cockpit, resulting in the pilot's subsequent loss of control during flight. Contributing to the accident was the mechanic's and the pilot's self-induced pressure to complete the work that day.

Circumstances:
The pilot was conducting a cross-country flight from Canada to California and had landed to clear customs into the United States and to refuel his airplane. The pilot then departed to continue the flight. During the initial climb after takeoff, the engine experienced a total loss of power, and the pilot attempted to make an off-airport forced landing. The right wing struck railroad tracks at the top of a hill, and the airplane continued down an embankment, where it came to rest adjacent to the bottom of a railroad bridge. Postaccident interviews revealed that, when requesting fuel from the fixed-base operator (FBO), the pilot did not specify a grade of fuel to be used to service the airplane. The refueler mistakenly identified the airplane as requiring Jet A fuel, even though the fuel filler ports were placarded "AVGAS (aviation gasoline) ONLY." The fueler subsequently fueled the airplane with Jet A instead of aviation gasoline. Additionally, the fueling nozzle installed on the fuel truck at the time of the refueling was not the proper type of nozzle. Jet A and AvGas fueling nozzles are different designs in order to prevent fueling an airplane with the wrong type of fuel. Following the fueling, the pilot returned to the FBO and signed a receipt, which indicated that the airplane had been serviced with Jet A. There were no witnesses to the pilot's preflight activities, and it is unknown if the pilot visually inspected or obtained a fuel sample before takeoff; however, had the pilot done this, it would have been apparent that the airplane had been improperly fueled.
Probable cause:
A total loss of engine power due to the refueler's incorrect refueling of the airplane. Contributing to the accident was the fixed-base operator's improper fueling nozzle, which facilitated the use of an incorrect fuel, and the pilot's inadequate preflight inspection.

Circumstances:
The crew was preparing the aircraft to perform a cargo flight to Calgary (flight NRL920). While taxiing, the aircraft went out of control, collided with a parked Ameriflight Piper PA-31 before coming to rest against a metallic fence. Both pilots were uninjured while the aircraft was damaged beyond repair.
Probable cause:
The NTSB confirmed that no investigation have been conducted about this incident. Thus, the cause remains unknown.
