## Discrepancy

INVESTIGATION FOR FLAPS STUCK AT 26 DEGREES, FOUND A BOLT INSTALLED IMPROPERLY.  BOLT (P/N A102-1/2G) INSTALLATION IS CONDUCTED PER HS125800 SB 53-82-3566G, ITEM NR 18.  IF BOLT IS INSTALLED WITH THREADS OUT, FLAP CONTROL INTERFERENCE CAN OCCUR.  PROPER INSTALLATION IS FOR BOLT HEAD TO THE OUTSIDE AND THREADS INSIDE.  RECOMMENDATION - RAYTHEON SHOULD REISSUE THE SB TO HIGHLIGHT DETAIL 'L' FOR PROPER BOLT INSTALLATION.  AN INSPECTION FOR PROPER CLEARANCE FROM SURROUNDING FLAP CONTROL LINKAGE AND A FULL FLAP OPERATIONAL CHECK SHOULD BE ADDED TO THE PROCEDURES FOR THIS ITEM.
