I think the AD is self explanatory. But I see no reason not to criticize FAA either. It is a valid opinion; for that matter, Boeing seems to be challenging the FAA as well.
At least from a public point of view, Boeing is making the FAA look bad, the FAA is making itself look bad, by hesitating, and Boeing is making Boeing look bad.
In the middle is a 40Billion dollar program with over 800 airframes sold.
Who defends the program? Not the egotists playing games.... This aircraft deserves better....
Who is defending the aircraft from a seemingly boneheaded decision to utilize high strung storage chemistry?
Enough Pride, and that embarrassing stubbornness. It's a beautiful aircraft, fix it. You're ten meters from the finish line, stop whining.
