Narrative:
Accomplished change order authority/authorized cabin pressure controller modification and the aircraft came back for pressurization problem. Callback conversation with reporter revealed the following information: the reporter stated the pressurization controller was delivered with the plastic cap in the sensing port and was not removed prior to installation. The reporter said the FAA has sent a letter of investigation which the reporter answered.
