the RA 1 fault looks to have been intermittent, so if it only happened away from base, detection may have been difficult. I understand THY said they repaired a RA (didnt say which one, but my moneys on no1) on 05 Feb. Wonder what they did? It could well have been on and off since.... the FDR suggests this. In my mind it should have been changed.
