Narrative:
On aircraft X (contract aircraft) I installed the fan filter and recirculating fan. I did not install the insulation on the aft bulkhead; and do not remember closing the aft bulkhead panel. After install of recirculating fan; I was told not to install panels on the aft bulkhead; so they could do pressure checks.
