Narrative:
After arriving, the engineer lowered the aft airstairs. The stairs dropped to the ground without hydraulic assistance. A logbook entry was made about the aft airstairs. A mechanic raised the aft airstairs manually and cleared the logbook discrepancy. I thought the aft airstairs were working normally. Upon arriving at the next destination the aft airstairs again dropped to the ground without hdy assistance. The aft airstairs should have been a deferred maintenance item instead of clearing the logbook.
