Maybe the swiss cheese holes found a good path...Why not stopping them before any procedure related to crew actions?
If there proves to be a common mode between MEL'd T/Rs and crew actions, then surely both would benefit from review?
Sorry to be harsh, but this is a "Professional Pilots' Forum". Unless you have actually studied and understood the applicable accident reports, and their recommendations, then proposing actions such as you do is about as logical as banning all takeoffs worldwide from RW36 because that was what the Spanair took off from
Thrust Reversers are useful, but rarely vital. They have numerous safety / indication systems to avoid the odd accident caused by a Thrust Reverser. Any unservicability with these systems - and surely it is far better to just lock the system out, and await a timely analysis engineering solution?
A knee jerk reaction to just "ban Thr Rev U/S under MEL" will lead to a lot of p***ed off Pax stuck around the world, and pressure to continue flying with a "slightly dodgy Reverser", or hasty, maybe inappropriate rectification to "clear" the fault. Invariably I would prefer to operate with an MEL'd Rev U/S (and locked out) than one I had the slightest concern about...
