Correct A4. quality seems to be an issue indeed, but not surprisingly if you read the Seatle Times..
On a comparative note, if one looks at the MA-60, one can see that the FAA at least takes things seriously..
In China and Indonesia , the largest MA-60 operators, the aircrfat continues to fly despite a much worse record than the 787 : only 64 a/c in service , 7 accidents, of wich 3 in 2 months .
But to be fair , the FAA did not certify it..
