All other changes are major changes. REASON/DESCRIPTION/OPERATIONAL CONSEQUENCES Following a review of eccentric bolt lives and failure conditions, it is now necessary to reclassify bolts as Principal Structural Elements (PSE’s) and introduce them into the Airworthiness Limitations Section (ALS) Part 1. This Service Bulletin (SB) supports the interchangeability of post modification 13594B0064 eccentric bolts on older aircraft and provides a means of removing the Slat 2 and Slat 3 bolt pn A578640512208 and associated washer pn A57864522200 from the fleet. This Service Bulletin replaces the affected eccentric bolts on Slats 2 and 3 at tracks 4, 7 and 8.
