Awareness and Quick Response Crucial to Avoiding LTE Accidents
Loss of tail rotor effectiveness does not account for a significant portion of accidents, but LTE does present training and safety challenges.

The sequence may seem inexplicable: a helicopter in apparently slow, stable flight begins spinning faster and faster until it falls to the ground. Its occupants may or may not escape, but the aircraft is usually destroyed. The likely cause or contributing factor: loss of tail rotor effectiveness (LTE), and raising the possibility that training for LTE is inadequate and needs to be reconsidered in light of these accidents.
