verything in aviation is based on cost-benefit, would it be cheaper to re-engineer the aircraft or live with this pretty rare issue and try to mitigate it?.
From many of the posts, including mx people, this issue appears to be far from rare.
In this case, it landed in an urban environment, and smashed an occupied vehicle window. Could have easily hit a person. It took this long to elevate the issue, but luckily, so far, no loss of life, but certainly the potential is there.
The lazy B's nonchalant attitude to pieces falling off of aircraft for years is a bit concerning.
