Yes after the autothrust disconnect, at 18:48:29, cf. p. 3, FDR graphs). In case of an "involuntary disconnect" of autothrust, i. e. any mode of disconnect other than bringing both levers to idle or pressing the pushbutton on the lever side, thrust remains locked. Until the levers are moved.
Thanks.
First let me just make a summary:
No controversy about A/THR behaviour. It worked as expected in any case in which one of the TLA readings remained in climb.
The right engine thrust never surpassed climb power as expected. It remained locked at ca. 1.18 EPR. after A/THR desengaged therefore below CLB power.
From here we have four possibilities:
1 - The right TL wasn´t physically brought to idle and remained "untouched" until the very end;
2 - The right TL was brought to idle but the TLA reading remained at CLB. The right TL remained "untouched" ever since. The crew didn't figure out right engine EPR was above idle;
3 - The right TL was brought to idle but the TLA reading remained at CLB. The crew tried to put the right engine thrust back to idle moving the right TL but the thrust remained locked;
4 - The right TL was physically locked, meaning that the FP couldn't phisically move it even when he tried to do so.
