  • I still can't see any of your messages to me. I read your last post and am getting frustrated that you are leaving out (according to what I have learned) a very important part of the rotor brake "system". You are failing to acknowledge the micro switch that is required to be closed at full forward stick to engage the brake.

    You are doing a disservice by not even considering the micro switch as part of the system and ignoring its importance. If builders are adjusting that switch so a flip to "brake" immediately engages the rotor brake, it would be a positive result from a tragic event.

    I "think" the brake switch only builds/reverses pressure. Then full forward stick hits the micro switch, opening a valve to engage the brake. So if a pilot pulls back on the sticks the braking effort stops.

    I will contact some owners to see if I can find out more info...

    Tim,

    Many of my replies to you haven't gone through, and what I see after sending them is only a blank box.
    It's a forum snag, sorry.
    I'll try this Private Message format, and see if it goes through.
    We can also go to email, if you'd like.

    Regarding that forward stick microswitch, you're describing "all systems normal".
    I'm sure that's almost always the state of affairs.
    But, something weird happened to N198LT.
    To me (and several others), the rotor brake somehow got engaged in the air.

    I would not trust a mere microswitch as the "brake safety" in regards to stick position.

    Chris seemed to have rudder control till the end.
    I think his passenger was not incapacitated, and not an issue.

    Speaking of turning FLIGHT to BRAKE, a student once did so during the takeoff roll, causing a crash.
    I don't know where the stick was then, or if the microswitch was defective or not triggered.
