58000FH is hardly "old". Well within the A320 design life.
The designlife of the A320-200 is (or was?) 60.000FH and 48.000FC
An Extended Service Goal Program is available which extends the life to 120.000FH and 60.000FC but it's unclear if this plane did get this program or not. If not then it was close to the end of it's life, if so then it had a long way to go.
