A320 flap/slat locked issue

Hi colleagues..
did the pilots in some cases responsible for the flap/slat lock activation ?

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.

No. The flap lever is actually an electrical switch. It's made of solid mettle only moves linear. There's nothing rough and smooth about it.

Long ago but I'll give it a try.

"Locked" = slats/flaps are stucked.
Slat/Flap system 1/2 failure... the other system, hopefully, works...

Slat/flap locked rest from MCDU clear the fault.
flap/slat fault problem is extended to more than SFCC

Not locked permanently, but if F 0 is selected and the speed is below 165 or AOA over 8 the alpha/speed lock function activates. FCOM 27 30 10 refers.

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.

When less than 7.1 AOA or over 171 kts the slats will retract if the alpha lock has been activated.

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.

slats/ Flaps Locked is a mechanical problem.
Slats/Flaps Fault is a computer problem.

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.
