Hughes 300 "beheaded" in Brazil - ground resonance?
Rnut
Have had a totth come off the ring gear in mr trx, totth about the size of first joint of little finger. Only knew about it when one could hear a clicking sound when the blades were slowing with engine shutdown. If that had wedged in the ring gear

There was a gearbox seizure in Canada a few years ago, in Quebeck.
It took the entire rotor system off, and spun the helicopter around a bit. This happened on the ground.
MRGB in overhaul put together wrong...

It looks like maybe the mast took off,they sometimes crack around the flight control support around the mast half way down and the pin wheel goes for a ride.
We had lower carriers crack back in the day and one bearing siezed on the ground,The rotor came to a standing still motion.

No thats a blade, can tell by the last section being yellow as per blades get painted, plus its too wide for a slat and the curve is wrong. But agree can only think that the trx seized. Mind you the heli is realitvle undamaged if it was flying at the time all things considered !

I think I am going to have to agree to disagree with you on this one, but that's not the issue. I think that the gearbox has recently been overhauled or the oil for some reason was maybe missing and like winnie says in Canada a few years ago a similar event occurred but the helicopter was sitting on the ground when it happened and this was due to an error made by the overhaul shop fitting a gasket the wrong way round and a critical oil port was covered! I also had this happen to me, on running up the helicopter after the gearbox had just come back from the overhaul shop the engineer spotted the oil pouring out from the seal and I shut down immediately. When talking to the overhaulers they came down that evening worked through the night and amend their error and they couldn't apologise enough. It's only really now that I can appreciate the consequences of what might have happened.
It seems this helicopter had managed to take off before they lost their rotor system, probably got just a couple of meters high....very very lucky to be alive. Thank god they are and hope they make a speedy recovery.
