James7:
I expect you're right though the gap between first & second "Retard" is 1.4 secs & between second & third seems 2.5 so I'm not sure when next one would have been due. No doubt FDR comparison will tell all. I wonder whether FDR will also show whether one or both TR applied by crew on previous POA landing. Haven't noticed anyone reporting when the TAM MEL changed - as someone suggested, would be handy if such op procedure changes actively notified (i.e. not just a paperwork update) & reasons given. I would assume that two experienced guys on this flight would have discussed TR lockout implications at least before first sector landing. Was the o/b MEL correct, one wonders?
