How … how often does that go wrong?!
- lisper 3y agoIt depends on what you mean by "that". Getting control surfaces actually reversed is not very common, but it does happen, typically after maintenance when a mechanic inadvertently re-connects a control cable backwards. Control cables also can and do break, but that too is fairly rare. What is not rare is control mechanisms jamming. Here is an example: https://www.ntsb.gov/news/press-releases/Pages/NR20230928A.aspx https://www.ntsb.gov/news/press-releases/Pages/NR20230928A.a...
- ahazred8ta 3y agoThere have been several cases of the landing gear up/down lever getting wired backwards during maintenance. Not to worry, the gear has a 'squat switch' sensor that prevents the gear from being raised when the plane is on the ground. Unless you taxi over a bump and the switch decides it's now airborne. Crunch.
