This [Report] is filed to report FAA violation.Aircraft arrived IAH with both engines t-r hinge bump fairings in wrong configuration. These hinge bump fairings are to be installed only on inboard side of both engines.  But; on this aircraft the right engine inboard t-r hinge bump fairing was completely missing - see log XXXXXXX and sdr# XXXXXXX. The right engine outboard t-r was configured correctly with no fairings installed.... Now; the left engine inboard t-r was configured correctly with fairings installed. But the left engine outboard side also had t-r hinge bump fairing installed and this is wrong. The outboard side of left engine should not have this fairing installed - see log XXXXXXX. See attached pictures of both engines correct and wrong configuration; Illustrated Parts Catalog reference and amm reference. In a nutshell; the left engine has an extra fairing installed on outboard side and right engine is missing the required fairing on the inboard side.
Technician reported that incorrect parts were installed on both thrust reversers.
