Peter's got a good blog on his site regarding the accident that took place today. Thankfully no fatalities.

Surprised or it's perhaps because I'm not engilsh native but it looks like the ski resort is really under estimating the importance of such issues !!! 4 chairs that slide that's insane !!

Per Liftblog, the investigation suspects the springs in the grips. The resort will replace the entire set (across the entire lift's chairs) before retesting and re-certifying.
Interestingly, also per Liftblog, the last set of inspections was just a month or two ago, in Oct/Nov 2017 -- including a load test. Prior to that, the lift operated through the summer season w/out incident.
Something got missed ... whether due to temps, weather, or whatnot, the certification process/testing clearly didn't catch this issue.

According to the report, the load test was performed in August and then grip service was performed in October.
My experience is grip springs don’t lose their strength overnight. And if the spring packs had weakened, the slip test that was required to be performed after re installation the grip should have identified the grips with weak spring packs.
I don’t think we have the whole story...

Somebody skipped a step. Buying all new springs is a kneejerk reaction ...
