Another Boeing "Issue"?

UAL says it wasn't turbulence. I seem to recall warnings about seat switches causing un-commanded altitude changes, but don't recall if that was for the 777 or 787. 787 Altitude Deviation

Seat switches?!?

Friday’s incident involved a Boeing 787, which was subject to review by the Federal Aviation Administration following a mid-air dive of a Latam Airlines flight last March. In that previous incident, investigators found a pilot’s seat on the flight had lurched forward and into the plane’s control column, causing the plane’s nose to drop.

Seat swaps probably, crew change

IIRC one of the crew pressed the power seat switch from behind the occupied seat and drove it forward into the column. IIRC the user of the occupied seat also had a meal tray in lap.

This is my recollection as well. Also that this switch normally had a cover and it was not in place.

That event was clearly a maintenance failure combined with a crew mistake.

This flight may have similar characteristics.

So a Cessna issue.

Our switches are rocker switches on the side of the seat, between the seat and the center console, they move slowly and it would be hard to accidentally hit one and hold it long enough to cause any danger. There is however a manual release but it’s even lower and not something you would likely accidentally hit, even changing seats for relief crew.

No idea on the 78
