A320 flap/slat locked issue
I think you are talking about the WTB (Wing Tip Brakes) that could be triggered by resetting the aircraft clock! Something to do with routine calender system checks. ie. running the clock through the time?

Does that still appear anywhere in maintenance manuals ? We had that on SOPs but over 10 (?) years ago as far as I can remember and it was subsequently modified.

Cheers guys,
ecam says slats/flaps fail/locked while the qrh says flaps/slats jammed.
why the wording is different ? Isnt locked and jammed meaning the same thing ?

Slat or flap fault is SFCC problem and ECAM will ask you to recycle to clear it. Flaps locked is wing tip brake activation and ECAM will not ask you to recycle as it is not curable in flight.

Alpha lock is not an abnormality. It is a temporary activation of a safety device. Off course it can be restored at correct AoA or speed. But flaps or slats locked or fault is an abnormality. Flaps or slats locked is permanent. Slats or Flaps fault is also an abnormality of SFCC malfunction. It may recover if recycled.
Not quite what the OP was asking but a crew in our company ended up landing in CONF1 after the small metal pin that holds the flap lever together (it connects the lift up locking part of the handle to mechanism) broke and left them unable to select any further flap.

Actually, there is a difference. The Jammed procedure in the QRH is for several scenarios including Slats Fail, Flaps Fail, Slats Locked, Flaps Locked, HYD G+Y SYS LO PR, HYD G+B SYS LO PR. A bunch of different faults(fail, locked, hydraulic loss) that result in the situation where the devices are considered to be jammed(immovable).

The ECAM makes a distinction between locked (hydraulic brake) and fault(computer problem) because the actions are different. There is no jam or fail. But once the condition is permanent then there is no more use of this distinction and you need to refer QRH procedure to execute approach and landing. It is referred as LANDING WITH SLAT/FLAP JAM Procedure. Reason notwithstanding it referred as jam.
