## Discrepancy

DURING ANNUAL INSP, DISCOVERED EXCESSIVE FORE AND AFT PLAY IN RT WING, PN 22-5708-00-00WIP.  MX RECORD REVIEW INDICATED THAT THE RT WING WAS REPLACED ON 4/25/09.  REMOVED WING TO INSPECT.  DISCOVERED SPAR, MAIN BOLT, BUSHING, PN 20-5700-01-20 WAS NOT INSTALLED WITH NEW WING.  ACFT FLEW FROM 4/25/09 TO 6/11/10 FOR A TOTAL OF 308.4 FLIGHT HRS WITH SPAR, MAIN BOLT, BUSHING MISSING AND IS CONSIDERED TO BE A FLIGHT SAFETY CRITICAL ISSUE.  REVIEW OF MM INSTALLATION PROCEDURES DID NOT INCLUDED ADDITIONAL INSTRUCTION FOR INSTALLING THE SPAR, MAIN BOLT, BUSHING WHEN INSTALLING A NEW WING.  SUSPECT THAT MM INSTRUCTIONS FOR REMOVAL AND REPLACEMENT OF THE WING WERE WRITTEN FOR REMOVAL AND REPLACEMENT OF AN EXISTING WING ONLY.
