Narrative:
Accomplished aircraft engineering change order rudder pressure reducer and yaw coupler installation. Installed/modified wiring per boeing documentation. Boeing supplied kit, had wrong part in kit that was tagged for a B737-200 aircraft. Rudder pressure reducer in kit was for a B737-300. We assumed the parts in the kit were for a B737-200 because the previous kits had all been correct. Supplemental information from acn 560458: the hangar crew installed correctly a rudder pressure reducer and yaw damper coupler. This was a -200 series aircraft. The kit fit and installed at the proper location. The problem is that boeing mislabeled a -300 series kit with a -200 series part number. No parts were modified or changed in any way to accomplish the installation. A fleet inspection should be performed to insure that no other aircraft had incorrect parts installed as a result of boeing's mislabeled parts.

Title: A B737-200 WAS DISPATCHED IN NON COMPLIANCE WITH THE INCORRECT RUDDER PRESSURE REDUCER INSTALLED. PART IN KIT SUPPLIED IN ERROR BY VENDOR.
Narrative: ACCOMPLISHED ACFT ENGINEERING CHANGE ORDER RUDDER PRESSURE REDUCER AND YAW COUPLER INSTALLATION. INSTALLED/MODIFIED WIRING PER BOEING DOCUMENTATION. BOEING SUPPLIED KIT, HAD WRONG PART IN KIT THAT WAS TAGGED FOR A B737-200 ACFT. RUDDER PRESSURE REDUCER IN KIT WAS FOR A B737-300. WE ASSUMED THE PARTS IN THE KIT WERE FOR A B737-200 BECAUSE THE PREVIOUS KITS HAD ALL BEEN CORRECT. SUPPLEMENTAL INFO FROM ACN 560458: THE HANGAR CREW INSTALLED CORRECTLY A RUDDER PRESSURE REDUCER AND YAW DAMPER COUPLER. THIS WAS A -200 SERIES ACFT. THE KIT FIT AND INSTALLED AT THE PROPER LOCATION. THE PROB IS THAT BOEING MISLABELED A -300 SERIES KIT WITH A -200 SERIES PART NUMBER. NO PARTS WERE MODIFIED OR CHANGED IN ANY WAY TO ACCOMPLISH THE INSTALLATION. A FLEET INSPECTION SHOULD BE PERFORMED TO INSURE THAT NO OTHER ACFT HAD INCORRECT PARTS INSTALLED AS A RESULT OF BOEING'S MISLABELED PARTS.
