Have to say 411A may have a point. 18 months ago I found all the BCFs in the loos on one aircraft were out of date according to the labels. In fairness to the company they did investigate and concluded that they were OK but just had not had the labels changed. In any event they were all checked and relabelled within a few days anyway. Does raise the question though that even if AA are OK do the companies that do maintainance for them let them down on occasions?
