While completing a local flight out from Reno-Stead Airport, the twin engine airplane landed hard for unknown reasons, went out of control and came to rest nearby the runway. One occupant was slightly injured and the airplane was damaged beyond repair.

The single engine airplane departed Reno-Tahoe Airport Runway 16L at 2058LT on an ambulance flight to Salt Lake City, carrying four passengers and one pilot. During initial climb, the pilot made two successive turns to the left according to the procedure then continued to the northeast. At 2113LT, at an altitude of 19,400 feet and at a speed of 191 knots, the airplane initiated a right turn then entered a spiraled descent and crashed one minute later in a snow covered prairie located southwest of Stagecoach. The airplane was destroyed by impact forces and all five occupants were killed, a pilot, a flight nurse, a flight paramedic, a patient and a patient’s family member.

The single engine airplane was on final approach to North Las Vegas Airport when it collided with a Cessna 172 Skyhawk owned by Binner Enterprises. Registered N160RA, the Skyhawk was carrying two pilots who were completing touch and go manoeuvres. Following the collision, both aircraft dove into the ground and crashed on the airport perimeter. Both aircraft were destroyed and all four occupants were killed.

While approaching class B airspace, the airline transport pilot was in communication with a controller who later stated that the pilot's speech was slurred, and the controller repeatedly asked if the oxygen system on the airplane was working properly. As the airplane approached a nearby airport, about 85 miles from his destination airport, the pilot stated he had the airport in sight and repeatedly requested a visual approach. The controller instructed the pilot to continue his flight to his destination, in a southwest direction. As the controller attempted to maintain communications, the pilot dropped off radar shortly after passing the nearby airport and subsequently landed at the nearby airport, which was not his destination airport. According to a surveillance video and impact marks on the runway, the airplane landed hard about halfway down the runway and slid to a stop on the left side of the runway. The airplane fuselage and wings were mostly consumed by postimpact fire. After authorities arrived onsite, the pilot was arrested for operating an aircraft under the influence of alcohol. The pilot was found to have a blood alcohol level of .288, which likely contributed to the pilot landing at the incorrect airport and his subsequent loss of airplane control during landing.

The airline transport pilot departed in the twin-engine, turbine-powered airplane on an air ambulance flight with two medical crew members and a patient on board in night visual meteorological conditions. According to a witness, during the initial climb, the airplane made a left turn of about 30° from the runway heading, then stopped climbing, made an abrupt left bank, and began to descend. The airplane impacted a parking lot and erupted into flames. In the 2 months before the accident, pilots had notified maintenance personnel three times that the left engine was not producing the same power as the right engine. In response, mechanics had replaced the left engine's bleed valve three times with the final replacement taking place three days before the accident. In addition, about 1 month before the accident, the left engine's fuel control unit was replaced during trouble shooting of an oil leak. Post accident examination revealed that the right engine and propeller displayed more pronounced rotational signatures than the left engine and propeller. This is consistent with the left engine not producing power or being at a low power setting at impact. Further, the abrupt left bank and descent observed by the witness are consistent with a loss of left engine power during initial climb. The extensive fire and impact damage to the airplane precluded determination of the reason for the loss of left engine power.
