rotorboy,

In an LTE study I did about 7 years ago, based on worldwide accidents of all helos, using four different data bases, this is what it showed:

95% of all LTE accidents involve Bell 206 models.

Virtually 100% of all LTE accidents involve Bell helicopters (one Robbie in UK was reported as LTE, but was probably over pitching).

My conclusion was that the inadequate size of the Bell 206 tail rotor was the principal cause of its LTE woes.
A second finding is that all tail rotor authority events were being called LTE because the marketing campaign conducted by Bell was effective on removing the heat from their design.

LTE really does not exist, it is a label used to blame the pilot when a marginal helicopter loses yaw control within its approved envelope. That does not mean that a 206 can be milked by an experienced pilot to not lose tail authority.

LTE cannot be experienced by any helo built to modern standards (larger tail rotor). It is impossible to get LTE in a Black Hawk, Apache, S76, H-500, EH-101, Lynx, etc because they have adequate tail rotors.
