[Low_volts]

Seems that CHC have had a rollover event with one of their 332L's (C-GGKX) over in Boundary Bay. No injuries mentioned.

Looks like a cord running up to the tr gearbox and then wrapped around one of the towel rack antennas. Balancing tail rotor? Just a ground run then. Checked the WX, no wind. What makes a Puma fall over?

CHC statement:-

Maintenance Incident at Boundary Bay Airport

VANCOUVER, BRITISH COLUMBIA--(Marketwire - Jan. 4, 2011) - An aircraft operated by CHC Helicopter was involved in a maintenance incident at Boundary Bay airport this afternoon at about 4 pm. The aircraft was not airborne and no passengers were on board at the time of the event. No one was injured and the incident is currently under investigation.
The aircraft is a Super Puma helicopter (registration C-GGKX) with seating capacity for 18 passengers and two pilots.
Safety is the number one priority of CHC Helicopter and we will co-operate fully with authorities to ensure the cause of this incident is understood. CHC Helicopter will provide an update as soon as more information is available.

I do know they have a quite high centre of gravity and in certain conditions can be a lot more susceptible to rollover than other types such as the S61N. The wheelbase when you compare them is very narrowly tracked on a puma.

Tail servo fairing missing in photo.
sn 2468, so a relatively 'young ' L1!

[ShyTorque]

Ground resonance a possibility, by the look of it.

[ShyTorque]

Someone always says that.

[malabo]

I hear it's common for CHC and Bristow engineers to do ground runs. Anybody know if this was a pilot or engineer at the controls?

[unstable load]

malabo,

In my years at Bristow Nigeria, CHCA and Global Ops we always had pilots do our runs for us.

[HeliComparator]

Ground resonance - AFAIK never happened on a 332L so highly unlikely. It has rolled over to the left, most likely cause is application of a lot of right pedal for some reason (maybe not monitoring pedal position). With no pax and not much fuel, and cyclic just slightly left of centre, it will roll over. Or it will roll over with cyclic neutral and wind from right (with full right pedal in each case).

Since tail servo cover is missing, perhaps maintenance intervention caused an issue with tail rotor control?

It's actually a 332L2 that spent the last six years in Brazil.

I'm almost certain the ground run will have been done by a pilot. Engineers doing ground runs seems to be a Norwegian thing - both HS and Bristow Norway.

Pumas seem to like lying on their side :E

[Helitemp]

Funny looking 332L2, with those sponsons and the tail rotor blades fitted most definatley an L or L1.:=

[Wizzard]

It's actually a 332L2

I'm afraid you'll have to hand your anorak in:= - that's not an L2, wrong tail rotor head/blades, wrong sponsons.

[malabo]

No need to wonder, just search the registration on the TC website http://wwwapps2.tc.gc.ca/Saf-Sec-Sur/2/ccarcs/aspscripts/en/current.asp

C-GGKX comes back with AS332L1, 1997 manufacture, Serial 2468, owned by CHC Global.

[030Outbound]

Definitely an L1......was bound for Australia.

[ironchefflay]

to add to someone elses comment, eagle eyed as it was,

it looks like a cable from an 8500 balancing kit, coming down from the top of the pylon and wrapped around the hockey stick where it would be if doing a balancing run. so doing a tail balance sounds plausible in this case. i only know of Norwegians doing ground runs with no pilots in CHC. not able to do that in UK certainly.

[Variable Load]

Yup, the spotters to the right have it :ouch: It is an L1. Me bad!

As mentioned above, was bound for Oz as VH-LYH.

[jp4toulon]

A problem with the servo-valve on Roll channel ( Moog valve) in the A/P Hydr block can bring the A/C to roll on to the side, if the pilot does not react quickly!
Occurs 2 or 3 years ago in malaysia, killing (if my memory is good) one engineer.

[forget]

Occurs 2 or 3 years ago in malaysia,

And long before that, in Sumatra.

[ramblingrotors]

JP4,

No there was no such aincident in Malaysia 2 or 3 years ago

[BedakSrewet]

But that was a 330J of Pelita....

[jp4toulon]

Sorry, but as a 332wi"ll try to get the pics! It was a 332
ASAP i "ll post them

[ppng]

Left L/G collapsed, aircraft rolled over, no-one hurt - end of story.
:ugh:

[pasptoo]

and i thought Heli-One were just touting for more work!

Glad to hear no one injured - especially as bits would be spread far and wide!

ShyTorque wrote Ground resonance a possibility, by the look of it.Canadian Rotorhead wrote"Forward servo found in fully extended position with flight controls neutral or flat pitch. This would cause uncommanded right and rear roll moment." PPNG wrote
Left L/G collapsed, aircraft rolled over, no-one hurt - end of story. Others alluding to tail rotor maintenance related incident and autopilot run away.Some have likened it to an incident in Malaysia some 3 years ago which from my knowledge never happened. (I’m sure the incident happened but not in Malaysia) Stories of it being a L2, a L1 and even the old 330j gets a honourable mention.(Still they are related by linage in a way)

If you’re all right and I have no reason to doubt that you’re not. Then those boys were indeed having a bit of very very bad luck that day.

There was a poster on here that went by the username of Idiot Spotter and all he or her use to write in his posts was "you have been spotted"
I miss his input
So as not to be hypocritical or to be hypocritical depending on how you read this. I would of guessed that the "wind just blew with light fuel" but a post earlier (No 2) states the weather that day was no wind. So probably not the cause, so who knows?
CHC people been told not to talk to the media which is probably standard these days. But come on guys spill the beans for us. Please

KNKT probes helicopter crash site in Pondok Cabe | The Jakarta Post (http://www.thejakartapost.com/news/2009/01/29/knkt-probes-helicopter-crash-site-pondok-cabe.html)

http://www.thejakartapost.com/files/images/1heli2.jpg


Investigators from the National Transportation Safety Commission (KNKT) have arrived at Pondok Cabe airfield in Tangerang to investigate the helicopter crash that killed two technicians earlier Thursday.

The crash site, located in front of Pelita Air's service hangar, was cordoned off and under police guard. Journalists were not allowed to enter the area.

The bodies of the victims, Ahmad Suparja (25) and Sri Setyobudi (42) were taken to Fatmawati Hospital in South Jakarta. The pilot of the twin engine Super-Puma helicopter, Rohman Hadi (50), and a technician who was inside the chopper, HM Hardi (52), survived, but were still suffering from shock.

South Jakarta Police chief Sr. Comr. Chairul Anwar said at the crash site the police had yet to figure out the chronology of the incident.

"What we know so far is they were doing a routine maintenance check. They started up the engine and the pilot began to lift the chopper when it suddenly collapsed," Chairul told journalists, as quoted by tempointeraktif.com.

He said the helicopter's blades had sliced through the two technicians. "It's quite severe, they were cut in two," he said.

Many thanks:D:D:D
It is the one i was thinking;)

[BedakSrewet]

The Pelita 330J Puma I was referring to was the rollover mentioned to have occurred in Sumatra ( must have been '70 -'71... ) and was a write off.

One has to remember that the 330 was originally designed for the French Army and had to 'fit' in a C-160 Transall for transporation to 'conflict areas' ( such as Cote Ivoire... ) and the main gear location -and width- was designed in accordance with the cabin / body width of the Transall.

Whoever was with Pelita in Indonesia that time, will recall the inherent 'Goyang Madura' movement of the Puma when the rotor started to spin up.

For the records, Pelita was the first civil operator of the 330 commencing ops in late '70 - early '71. Among the various operations performed extremely well by the 330 was 'moving' heli rigs in North Sumatra whereby 2 Puma's ( and a Alouette 3 to carry the sling cables back ) were operating in excess of 11- 12 hours per day over a period of 5-7 days ( if I remember well ) without stopping the rotor / engines ( yes, 'hot refueling' was done, and change of crew at the same time ) which contributed to the -almost- 100 percent serviceability of the Puma, which shows that the more frequent you fly them, the less technical problems one has.

Those were the days......

[ReverseFlight]

"It's quite severe, they were cut in two"

Nothing to cheer about ... absolutely horrific.

[poppahymen]

What did poppahymen then predict for 2010, 2009, 2008, 2007, 2006 etc..?
A true oracle in my book.. Well I could tell you all my predictions for 2010 2009 2008 etc but you would have to be a pretty trusting kind of a chap to believe. I think the real test would probably be from 2011 and on. Alas I am no new Nostradamus and refuse to make predictions involving animals, world events, the end of the world etc. I will leave that to crack pots, quantum science and the chaos theory people. My comments are not a prediction but merely a tongue in cheek observation of human nature and egos that accompany them in this good old world of ours.:):):)
Now if only the CHC blokes would spill the beans

[Winnie]

The CHC blokes sorta already did through someone else...

It is all written down.

[Canadian Rotorhead]

Thanks Winnie.

I deleted four posts here after some wonderful basement dweller doubted my credibility. I'll stick to another forum.

[Winnie]

Ya no worries mate.

See ya there!
