I think the big problem for Boeing is re-establishing confidence in Boeing.

Only last week I was commenting how cool Boeing and the FAA were after the first 3 incidents
in a week (APU fire, fuel spillage and brake problems). They shrugged it off and called it "new airplane (sic) problems" and said the aircraft was "safe" and no investigations were required.
If I were Boeing I'd be examining each incident in detail as none of them were what I'd call "minor" problems, and the proximity of each was becoming farcical.
