I've found one side twisted quite often and found it clipped in the wrong way. Not good when it's the buckle side.
No problem, can be removed and installed the right way round without the need for tools. I do that frequently, I would estimate around once in 10 flights it is installed the wrong way... So much for quality control.
Worth checking that the passenger in the adjacent seat doesn't also have a twist in his/her buckle belt.
Smart idea, but does not apply to business class seats
There is only one correct configuration! (At the risk of sounding like a complete bore!). That which is in the AMM....
Reading from left to right belts should be fitted
Tip/Buckle, Buckle/Tip, Buckle/Tip !aisle! Tip/Buckle, Tip/Buckle, Buckle/Tip
should probably better read
Tip/Buckle(Lid up), Buckle(Lid up)/Tip, Buckle(Lid up)/Tip !aisle! Tip/Buckle(Lid up), Tip/Buckle(Lid up), Buckle(Lid up)/Tip
Just for the very stupid type of AMM user...
"did it in accordance with the AMM, it does not say which way to install the buckle, so it is optional"
