The 787 seats are electric and operate via rocker switches that move them forward or aft and up and down, in the past they have been stuck travelling, if you’re in the seat and this is happening though you can stop it with a seat power cut off switch.
...if you have the presence of mind to stop trying to free the primary switch and remember there's a secondary switch, and also remember where it is and to operate it in the short time available...djc206 said:
Didn’t something similar happen to a Voyager when one of the pilots manage to wedge his SLR camera on the joystick and it lost considerable height at a crazy rate?
Oops!
Not only that, he lied about it resulting in an expensive investigation into the aircraft's control hardware and software, plus he put unreasonable pressure on the co-pilot to cover up the real cause of the incident as well. Oops!

We’d use a PED kit which involves things like gloves a mask and a fire suppression pillow and blanket etc
You’d put on the gloves and place a fire suppression pad on the device and then cover it with a fire blanket, the suppression pad melts and extinguishes the fire and then pick up the fire blanket with the device inside and place it in the PED bag.
Works really well.
Obviously if you can’t get to the device easily to place it in the bag etc you can use a fire extinguisher first.
I’m sure I’ve seen a similar piece of kit on a 737 owned by a Leeds based holiday airline. It appeared to be a saucepan with a long handle. I guess if you get the phone in the pot & close the lid it would probably do the job eventually.You’d put on the gloves and place a fire suppression pad on the device and then cover it with a fire blanket, the suppression pad melts and extinguishes the fire and then pick up the fire blanket with the device inside and place it in the PED bag.

There are so many engineering questions with this....
1) why are the switches coming lose?
2) why is the cover/switch designed in such a way that they can interfere with each other with such a small amount of movement?
3) why is the answer to the issue a maintenance bulletin telling ground crew to check the switch, rather than supplying updated ones which don't have what appears to be an inherent fault? The issue has been known about since 2018 (? from memory).
Not looking very good for Boeing. Apparently in the early 2010's they let 900 quality inspectors go!
