- Contexto
- The tail rotor assembly consisted of five rotor blades, labeled red, black, blue, yellow, and white and attached to the tail rotor hub. The outboard 35 in of the black blade was found about 5,100 ft south of the crash site. The remaining four tail rotor blades were attached to the tail rotor assembly. The tail rotor blades which remained attached to the hub had been bent, scraped, and broken during impact; there was no indication of preimpact failure. The black blade fracture surface appeared to be a progressive-type fatigue failure through the blade spar.
