• The PC-12 aircraft had a pilot, nurse, paramedic, patient and a family member on board.

An emergency medical flight carrying five people crashed on Friday night and left no survivors.

Five people, including a nurse, paramedic and patient, were killed when the air ambulance crashed.

Care Flight, the air ambulance operator, said in a statement that there were no survivors. It said the single engine Pilatus PC-12 aircraft went off radar near Stagecoach in Nevada.

"We are heartbroken to report that we have now received confirmation from Central Lyon County Fire Department that none of the five people on board survived," Care Flight said.

It was in the process of notifying the family members and said the five people on the aircraft were the pilot, a flight nurse, a flight paramedic, a patient and a patient's relative.

The Nevada-headquartered air ambulance service also said it was in a "passive stand down" as a safety measure, meaning that it was not transporting any patients at this time. The company, part of REMSA Health, said its immediate focus was to help authorities, staff and their families.

The cause of the crash is being investigated by the Central Lyon Fire Department, Lyon County Sheriff's Department, and the National Transportation Safety Board, Care Flight said.

The crash occurred about 9:15 p.m., Lyon County Sheriff's Office told ABC News, around the time when it started getting calls about a possible plane crash some 45 miles east of Reno. The plane was then located close to 11:15 p.m., but no survivors were found, the report added.

Care Flight operated four helicopters and one fixed-wing aircraft and has provided air ambulance services in Nevada and California for almost four decades, according to its website.
