I replayed this several times. Although we can’t see the rotor tach or the annunciators because of all the gadgets, the horn came on pretty quickly. That means the Nr dropped below 97%. You can tell he was adjusting the collective because it went on/off a couple of times before it stayed on. There is an option to drag the Nr down to no less than 90% in order to stretch the glide range. However, that cyclic flare is needed to build the RPM back up to give the blades enough energy for the decel and touchdown. If the pilot is too aggressive on the flare, the blades can strike the boom, but since directional control wasn’t lost, I’m guessing it was severed during the sudden stop of the touchdown.Very well done by the pilot. He had to turn away from the powerlines by the road and put it down between some brush. In prefect hindsight he could have killed his forward momentum some more, but I don't know anyone who could do much better.
The engine won’t start or run with the mags off. Unless this is something different in a helicopter?Saw this discussed on another forum but it looks like the mags were in the off position at takeoff. You can see this at 0:17 in video. Also, the pilot's reaction after crash at about 2:03 where he sighs "Aah... it's all right.." after touching the mag switch and maybe realizing that the switch is off. He has a strange aha kind of grin on his face. Interesting.
It would with a broken P-lead. You could imagine someone choosing to defer repairing that since there’s no prop starting danger like an airplane. Not legally of course, but it’s a plausible justification.The engine won’t start or run with the mags off. Unless this is something different in a helicopter?
That engine didn't sound right from the get go. But...that looked pretty damned well executed.Looks like he handled the engine failure pretty well given the time and place of the engine failure. Not a heli guy myself but found this interesting...
