Looks pretty nasty to me. I cannot see what happened though.

Looks like the helicopter clipped a cable while installing a Christmas tree. Reposted from the thread I opened before I saw this thread:

TV3 was filming when the chopper crashed 45 minutes ago. The pilot escaped without being seriously injured. But watch the video and you'll see he almost falls out of the chopper into the rotor blades. News is reporting that he was possibly carrying a passenger underneath in a human wenching operation but I haven't heard anything about that person's condition.

CAA's press release:

Quote:
CAA to investigate helicopter accident at Auckland’s Viaduct Basin

The Civil Aviation Authority will investigate an accident involving helicopter ZK-HIG at Auckland’s Viaduct Basin this morning. Safety Investigator Steve Walker will arrive at the scene early this afternoon, and Aviation Safety Adviser John Keyzer will join him.
Steve’s first steps will be to examine the wreckage in situ, interview the pilot and witnesses, and to develop a clear understanding of the work that was being carried out.
Once Steve has completed his examination of the wreckage it will be released to the owner for removal.

A preliminary can be expected within four weeks, and will be published on the CAA website.

Will keep y'all informed.

Here is the same footage but you can see the chooper hovering for a few more seconds before the crash.

Violent crash and hows the screaming noise the chopper makes. Where's that coming from?

Lucky pilot - time to by a lottery ticket.

I would agree with that.

My guess is a turbine over speed, the engine is still running (see the 17 sec mark in the video posted in reply 4 you can see the exhaust increase below the rotor hub) however it is no longer loaded. I assume the gearbox failed with the sudden reduction in the rotor speed allowing the engine to rotate freely.

Yeah, sounds like the engine over-speed as the pilot obviously shaken up didn't kill the engine. He actually looks like he was almost thrown from the chopper.

Thank goodness he is safe and will be around to celebrate the Holidays with his family.

I think I disagree - I never heard any increase in speed - only a slight decrease and increasing noise. I think, rather, that due to mechanical damage/distortion something started impinging on a rotating part of the turbine - think a playing card in the spokes of your bicycle. What we hear is the turbine - or some rapidly rotating part hitting something stationary. If you watch the second video - it runs for a few seconds, then starts to wind down as the engine quits.

Alternate explanation - that was the sound of the insurance company accountants screaming.....

This is playing widely on early morning television here in Europe. No matter how often I watch it, I am still amazed the pilot walked away. One lucky guy, he got his Christmas present early this year!

Interesting how the tail boom fails. I don't think the main rotor blades strike it, and I don't think it strikes anything itself. Just looks like the vibrations are too much for it.

Here is some footage from a better angle courtesy of TV3. Amazing that no one was injured.

If you look at the 3news link, it's quite clear that the main rotor clipped the wire. There is a chap who pulls on it in an apparent effort to give more clearance; however his actions appear to be the cause.

Not really. Yes, he wasn't killed or injured, but "lucky"? Hmmmm.

My office is just around the corner, we all heard the crash and wondered what it was, but there has been a lot of banging and crashing going on in our building due to refitting of the floor above us and another floor below ours, so although it was unusually loud we just shrugged and went back to work. It was a few minutes before we realised what it was that we had heard as we were not in direct line of sight, Very glad to see that the pilot was able to walk away and that no one else was hurt either. The news footage is amazing.

I understand that, but it looks like the vibrations from the main-rotor wire strike then cause the tail boom to detach.

I do not know to much about helicopters. But in the footage in reply 11 you clearly see the man under the helicopter pull a cable and then the chopper react at the same time to this pull. Can anyone shed some light on the possible link between the man pulling on the cable and chopper reacting and crashing, for me?

What would you call it. A rehersed staged performance? I think lucky is a very appropriate term.

No, there is a definite increase in turbine speed (or at least pitch), from when the helicopter is flying to when the rotors are no longer functioning, but the the turbine does slow back down some. The Turbomeca (or any turbine of similar nature) makes a horrendous racket at high power, and that's exactly what you hear after the helicopter comes to a stop.

That guy who picked up his camera and ran off just prior to the crash (in the 3News clip) must be kicking himself.

Yes he was. Rescuers said they had to unstrap him to get him out.
