CHC 332L Rollover Event at Boundary Bay
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?

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.

Ground resonance a possibility, by the look of it.

Someone always says that.
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

No need to wonder, just search the registration on the TC website http://wwwapps2.tc.gc.ca/Saf-Sec-Sur...en/current.asp
C-GGKX comes back with AS332L1, 1997 manufacture, Serial 2468, owned by CHC Global.

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.

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.
