Groundings are temporary restrictions against the original issue type certificate while it is being brought into compliance with the original specification.
From what I have read there is no varriance identified against the type certificate. For all we know this could be purely an operational problem and nothing wrong with the design.
If you support grounding, then just how far do you go? All recently certified aircraft from all manufacturers? Or do you feel there is supportable evidence to limit it to one manufacturer?, one aircraft type?, one model year?, one or two line numbers? or one operator's fleet?
When all is said and done what corrective action will place this large piece of capital ownership back into service in what time frame?
Certainly any of you can play a ouija board and decide to ground yourselves from flying anytime you choose, but I prefer to abide by a process of a rational approach.
