Facts are;
It broke
It got fixed
It's now back in service
those are not the facts.
the aircraft was flown in turbulence on descent at Vmo (maximum operating speed) the turbulence penetration speed is some 50 knots slower than Vmo.
the pilots did not realise that the aircraft was being structurally damaged by the descents.
aircraft continued in service until a bird strike caused a mechanic to have a look at what the damage was.
the inspection showed structural damage that had escaped the manufacturers inspection procedures, (built as they were on slower speed assumptions and lesser structural loads.)
there is obviously more to it than this potted history.
two of the manufacturer's test pilots flew that repaired aircraft back to Toulouse. presumably this will allow the designers to investigate what will be needed in the design to prevent a recurrence.
your mileage may vary.
have a safe flight.
