Okay, the bad messages from Boeing doesn’t end: The flight blogger reports , that Boeing has to replace of nut plates because of non-conformance to specification, as they used ones without an anti-corrosive coating. Mechanics have to remove thousands of plates and place new ones per aircraft.
To add insult to injury, it’s likely that several already flying planes have the same non-conforming plates:
According to Boeing, 737s delivered to customers since August 2007 contained non-conforming nutplates. Boeing's delivery website says that 394 737s were delivered between August 2007 and October 2008.
