Bell 505 down in Georgia 🇬🇪

[nomorehelosforme]

See below links to 2 news reports both state 3 people died and one states that it was not a wire strike. Another mountain crash, wondering what the weather was like that day? How many 505 crashes have there been?

Did anyone notice the tall tower right in back of the wreckage picture? coincidence?

The video shows an aircraft at 100KT or faster, descending with 1500 ft/min or more in a straight line into slightly raising terrain. Explosion on impact. None of the newspaper articles cited give a time of day when the accident happened.

Could it be that the video was taken by a night vision camera? Not an inkling of flare before impact, And definitely much faster than a night autorotation would look like.

It looks to me like it's spinning and out of control all the way to the point of impact. I don't see any explosion, just an eruption of dirt as it hits the ground.

What is minimum rpm to recover after engine failure at 6000 ft flying 100KT with 20KT tailwind and how much time is in between?

[fly4mo]

No wire strike!

the Video was taken at daylight in the morning

Don't know what the background of that question is but what we see in that video bears not the slightest sign of lack of any kind of energy...
Video quality is lacking but at least in the slow- mo it looks like its spinning. The trajectory is pointing slightly progressively downward. Difficult to dicsern in the video if the Main rotor was still intact and attached, although the trajectory is probably a bit too straight for a missing Main rotor.
Still I would not completely rule out a high speed wire strike stripping the MR.

Both MR blades were still attached, even after the wreckage came to a grinding halt. You can see them perfectly clearly in one of the post crash pics. The tail boom was not attached.

OK, saw the pictures. You're right.
If loss of tail boom (for whatever reason) at high forward speed would produce such a flight profile? Maybe...

[gulliBell]

Yep, it most certainly could.

[fly4mo]

low rpm after engine problem at 6000 ft with tailwind?

low rpm after engine problem at 6000 ft with tailwind?

that notice doesn’t seem to have any relevance to this accident since it involves frozen valves above 13000 ft.

from Robinson I know that there is less time to recover rpm at this altitude. the blades touched earth bended up and broke in two pices wasn´t that like low rpm

[gulliBell]

Helicopters don't spin at high forward speed at the rate we saw in the video if they still have their tail boom/vertical fin attached, and particularly with the engine not producing power. There is engine power spinning that thing, and no vertical fin or TR thrust countering it.

[The Sultan]

It looks in the video like the boom and fin are attached. If the tailboom had separated the ship would flip not spin in relatively level attitude. So loss of tail rotor thrust for whatever reason seems obvious. As the 505 has a well proven drivetrain design error can be excluded. This leaves maintenance error, FOD or bird strike as probable causes.

If you read the media coming out around the event, “officials” say there was no wire strike because there was no power outage in the area. That seems to be a weak argument for no wirestrike. Many support wires exist in the world that would take a rotor strike and it wouldn’t be obvious without further investigation. The crash video appears to me like Some kind of external impact removed major components and led to complete loss of control. Could be an animal, vegetable or mineral.
