From page 40 -
* the loss of the normal law between 2:05:10 and 2:10:06. The position of the rudder limiter, set by the rudder travel limiter unit (RTLU) is locked at 2:10:04.5 and this function is recorded between 2:10:17.5 and 2:10:18.5.
NOTE: The report uses "stuck" instead of "locked".
From page 89 -
* 2 h 10 min 18 - The ‘TLU 1 availability’ and ‘TLU 2 availability’ parameters become NOT AVAILABLE.
From page 112 -
* TLU 1 and TLU 2 parameters repeated, and at 2:10:08 the Side Slip from IRS becomes ACTIVE.
I suspect this is related to the Yaw Damper.
I've previously commented that the Rudder Pedal demands (up to RTLU limit) had the Yaw Damper output algebraically added.
