Now defunct (I believe) South Pacific Island Airways lost a Twin Otter from the Pago Pago base on the island of Ta'u in about 1984 due to the same problem on short final. The guys got it down, just, but it slid off the dirt strip into the bush and caught fire. Can't recall if there were pax casualties, but I know the American captain survived and returned to flying not too long afterwards.
I seem to recall (but open to correction) that the corrosion of the elevator cable was attributed to the local pax habit of travelling with badly sealed buckets of fish in saline water which were carried in the aft hold and tended to leak.
