Very weird 206 crash video Langley BC 20 May 2021
 

Is this some crazy visual illusion, or is that thing spinning clockwise? The video doesn't appear to be reversed or mirrored, the tail rotor is on the correct side, the leading edges seem to point counter clockwise as they should. Any theories what is going on here? Media says this happened "after undergoing maintenance".

Camera frame rate, a tutorial.

hello,

it is impossible to start a turbine in the wrong direction even if it would be possible the free whelling unit behind wont drive your gearbox. The picture fom highrpm shows the debris from the impact spreading away in the correct direction. So this is just an ilusion.

Take off like a brute, and instantly overpitch it. Great job!

If that was 'post-maintenance' then don't let them service your helicopter...........

Very true the frame rate makes it look compelling, but it is just that.

Check weight and balance hover? Fire extinguisher in proximity? Well done the guy under the 500, quick thinking and abnegation of his own security to go and help. Respect.

Take Off to Landing...constitutes one flight.

How does the guy log the time for this one?

If he cannot log any flight time....does it count as an Accident or Incident?:ouch:

Logging it as P i/c would be a bit cheeky. . .

To be fair, he did walk away from it so does it count as a good landing?

According to the owner of the helicopter, I suspect not.

PIC assumes a pilot, looks more like a couple of kids that learned on an iPad sim app.

Someone with sharper eyes than mine may be able to pick up more detail. Registration isn’t current.

How about attaching the tail rotor blades the wrong way around. The would cause them to go into overpitch which would overcome the pilot.

Not new. The first Puma that came out of centralised service at Odiham came out with the main rotor blades mounted the same as the Wessex.

I know because I was going to do the air test..

I have seen an Alouette III that flew fine with the Tail Rotor Blades on in reverse.....would have been signed off after the Air Test until a sharp eyed individual noted that minor discrepancy

Mr. Murphy must have immigrated to France where he took up Helicopter Design Engineering.

For the record I was engaged in winning a round of Uckers while that was happening.

If it's clockwise, why is the debris plume moving in the anti-clockwise direction from impact of the blade?

I think that screenshot solves it. The transmission is moving to the right, as it should with the blade at the top of the frame having just hit the ground in the normal counterclockwise direction. Well then, maybe someone just rolled it up to 100% with the collective halfway up or something.​​

Almost looks like something had snagged the front of the skid and tripped it.

Is there a good reason for helicopters to shift to forward flight immediately on takeoff rather than to ascend vertically for a few hundred feet before heading out?
Iirc, some recent accidents might have been avoided that way.

Ummm... yes... it needs a heck of a lot more power to climb vertically, and it puts you into the Avoid area of the Height/Velocity curve.

Forward speed increases lift - just like on a fixed wing. It's just not as critical on a helo.
