Well after 5 months and some large bills to remedy MRGB corrosion issues (that we feel strongly we shouldn't be paying), it looks as though Richard08h and I will soon be back in the air.
We're aware of at least six local EC120s that have suffered from this problem and there seems to be substantial evidence that indicates that the issue is down to a fault in the manufacturing process, rather than due to post production environmental conditions/maintenance, etc. as EC would have us believe.
We're contemplating a class action, comprised of owners who have been affected by MRGB corrosion problems. If you'd like more information and/or would like to be included, please PM me.
