There was also the issue of the missing wheel spacer on the Concorde that although it was demonstrated to cause much mayhem with the landing gear, was completely ruled out by the french.to the dismay of the AAIB..easier to blame the yanks...if 411A is keen to blame maintenance, then it would seem that some posters here are just as keen to rule it out..may or may not be...we'll soon find out...anyway if it's third party maintenance, doesn't reflect badly on AA as an operator does it?
