Is loss of tail rotor effectiveness common in the B407 when in a landing profile with a slight TAILWIND? Or if LTE is aided by putting in right pedal with a high power setting? |

Extremely rare compared to a 206, but I can remember seeing at least 2 crash videos of 407's which were pretty obviously LTE.
So not impossible, but if I remember right it's not mentioned in the RFM like in the 206 manual.
Been a while but I felt the 407 T/R was VERY responsive. |

LTE or Unanticipated Right Yaw. If one pays attention to performance charts, wind direction and velocity the loss of tail rotor athority is a non problem. There aren't any cases of loss of tail rotor authority if the aircraft is'nt operated over allowable performance gross weight and is operated within wind limitations. Some aircraft have a smaller margin of safety but all are safe if the pilot operates within the limitations. Buttom line, much like other aspects of safety, the pilot is generally going to be a big part of the problem in crashes. |

Every traditional tail rotored helicopter has the potential to be in high GW. High altitude. Unfavorable wind azimuth or a combination of some or all of those conditions and the pilot will have a high collective power selected when the T/R will reach at or near full pitch based on pedal placement by the pilot. And it will still start a nose left yaw. If the above control inputs are rapid you can expect a rapid event when the t/r no longer produces enough counter active thrust.
The condition has many fixes. First reduce the collective to a lower setting and simutainiously Unload the t/r to near neutral then smoothly input left pedal to stop the right yaw. Smooth is slow here friends.
Where I fly the airport is 6000msl and the work goes up to 13,000msl with d/a altitudes outside the charts so this exact thing occurs regularly. It's nothing to panic about and often avoidable once that TQ gets high and left foot is reaching uncomfortably. |
