Quoting Iflyswa (Reply 1): deontological theory and moral idealism have no place in this industry
Apparently not, but its not only the airlines and Boeing which are to blame, the FAA should also look to itself, because when you let planes fly which occasionally show:
Quoting PlaneHunter (Thread starter): uncommanded rudder events
You'd need to take more action than they have been doing so far.
I realise the incident/accident rate has been low, but these uncommanded rudder events have lead to several crashes in the past already; France and the UK once grounded all Concordes because of a design weakness to its fuel tanks which led to the crash in 2000, the FAA should take example to them regardless of the number of affected planes in operation.
BTW, anybody dares to imagine the ranting on this site if an Airbus model would suffer from such a thing as uncommanded control inputs which do not have their cause determined yet????
Every so many weeks the notorious AA A300 tail brake off accident comes up again as proof of how 'bad' airbus planes are, whereas in fact the F/O gave all the inputs making the rudder swing and ultimately lead to the tail breaking off: on the 737 however we have had the problem of uncommanded rudder deflections for years, yet nobody seems to think this is totally unacceptabe....

I believe the FAA has issued at least one (if not more) ADs specifically pertaining to the 737 and uncommanded rudder events, and requiring closer inspection as well as design modifications to the affected systems. The 737 is a safe and reliable airplane, but issuing an AD to retrofit the entire existing 737 fleet with the advanced recording technology is not a solution to the problem. However, identifying and addressing a potential defect necessarily requires the data and information that these recorders could provide, which is where good corporate citizenship is called into question. If airlines and the manufacturer even considered this to be a serious defect (it is, if it indeed exists), then why not retrofit just some of the 737 fleet, particularly older types? Costs would be significantly mitigated, sufficient data could be collected about the supposed defect, and a viable and worthwhile solution might then be developed.
Opinions expressed by "iflyswa" are not those of Southwest Airlines Officers, Directors, or Employees.

Are uncommanded rudder movements still a potential issue or were they "fixed" by a prior AD? If the issue was resolved by a prior AD, I'm not sure I understand why there is a need to retro-fit aircraft with additional monitoring. On the other hand, if there are still incidents' of uncommanded rudder movements then the FAA and airlines would be completely out of whack to not implement the recommendation.
