An [Aircraft Status] Turnover from third shift to day shift involved the replacement of a First Officer's windshield replacement where the seal installed was not correct for the Mod status of the aircraft. The seal was installed by third shift and the turnover to day shift started with the windshield being ready for install on the airframe; which is where I; [Mechanic X]; took over. I installed the windshield with no problems and the Operational Leak Checks were good. I am not sure; but I feel that the event occurred prior to myself getting involved. I feel that it is and has always been important to verify that the correct parts are used according to effectivity.
Company EMB-145 aircraft arrived at the hangar for a Windshield Heat Fault. After troubleshooting; [it was] determined bad windshield at First Officer's position. Windshield was removed and the aircraft was prepped for new; by Mechanic Y. I looked at windshield frame for proper prepping; along with sealant in four corners. I looked at the new windshield and provided oversight during the new seal for proper installation and everything looked correct. The shift was ending so a [shift] turnover was generated where the Mechanic signed-up to the specific task and I signed the RII. [There was a] misunderstanding of seal effectivity. For my involvement; make sure to ask the Mechanic about his experience with the task at hand. Verify the 'Effectivity' of the part being installed more closely. Talk to the Lead Mechanic to ensure that at least one of the mechanics performing the work has done the job before. Mechanic; who installed window; caught the error and had called Maintenance Control to have aircraft removed from service.
Four mechanics and one Inspector report about their involvement with a First Officer's Forward Windshield replacement on an EMB-145 aircraft. An incorrect pressure seal had been installed; requiring aircraft be removed from service.
