Blackhawk 86-24500 was lost in the early 90's at Ft. Chaffee, Ar. I believe the tail rotor retention washer (then made of aluminum) cracked in half and caused the aircraft to enter a spin. The aircraft was lost and soldiers were killed. I believe the aircraft belonged to 3/160 Nightstalkers.
The accident investigation team requested one of our aircraft (86-24501) to fly over for a comparison.
