After the show was canceled the chopper was sold to a German firm. Airwolf - as a Bell 222 - flew as an air ambulance. On 9 June 1992 it crashed during a thunderstorm, killing all three crew members.
During filming, a Huey helicopter crashed during a maneuver in Pico Canyon in California. Reid Rondell, Jan-Michael Vincent's stunt double, was killed, and a special credit appeared at the end of that particular episode dedicating the installment to him.
In order for Airwolf to fly with it's weapons deployed, they needed special permission from the FAA. Even though they were props, the FAA insisted on it.
