Gretchenfrage: maybe you could suggest something that doesn't involve grounding one of the worlds' most popular aircraft?
Let's not pretend other manufacturers have a perfect record. Didn't two/three jets from another manufacturer end up a smoking holes before anything was done? I took ten years from the first hull loss and it took a FAA AD to get the problem fixed.
The super simple OEB will bring the aircraft safely under control. All pilots are aware. My airline forces us to carry a copy of OEB48 and OEB48 is listed on each and every OFP. So there can be 9 copies of OEB48 on a flight deck at any one time.
