Its a pretty basic problem that should have been sorted out years ago after the first few incidents, the cowls have a latching mechanism that allows the panels to appear correctly fastened when they are not.
I am quite sure, given suitable motivation (threatened withdrawal of type certificate perhaps), the manufacturer could design a mechanism that solves that anomaly. A pin with a large "remove before flight" tag that must be inserted into the latch before it can be opened and can't be removed until its properly closed would be one approach but I am sure there are others.
We can only hope that this incident finally provides the impetuous to get what is a long running problem sorted out before it kills. However, knowing how this business works I will not be holding my breath.
