Would current ec 135 drivers dispel this following (ridiculous) idea of mine please as it sounds too far fetched to be true. But I need to air it:
When I first flew the 135, I remember an issue with the rotor brake "chattering". The pads occasionally touched the brake disc. It wasn't a big thing at the time and moves were made to sort it.
Question then: IF the rotor brake was applied in flight (either inadvertently or on purpose
) would it be man enough to initiate the following scenario (or would it be too small a system to slow the rotors in flight such that it was merely a severe embarrassment):
Rotor brake pressure applied - Nr begins to decay
slightly, Drags Nf down causing the engine(s) to stall/surge. [Eye witnesses report popping and spitting] Pilot sees and hears this but (obviously) doesn't connect it with a rotor brake problem - he sees it as an engine(s) problem. So he tries to identify the source but the noise(s) and (slight) drop in Nr troubles him to the extent that his best course of action is to remove the stalling engines. So he sets himself up for an auto and chops the throttles (all of this has taken seconds to decide and all the time the engines are popping and surging). He chops the throttles but the rotor head now much more easily slows down as the rotor brake has no engine resistance fighting against it. Engines are off, Rotors are stopping??????
