DURING THE PROCESS OF GAINING ACCESS TO THE FAIL-SAFE STRAP TRIM OUT AREA, IT WAS DETERMINED THAT THE INSTRUCTION IAW REV 1 OF THE SB WAS INSUFFICIENT TO REMOVE THE T-FITTINGS. MFG WAS CONTACTED VIA FIRST RESPONSE ON 6/9/09 AND THE SB ENGINEERING GROUP RESPONDED WITH THE INSTRUCTION REQUIRED VIA E-MAIL ON 6/10/09. THE SKIN STIFFENERS (T-FITTINGS) WERE REMOVED AND CORROSION WAS FOUND ON BOTH THE LT AND RT SKIN STIFFENERS (T-FITTINGS). IAW THE SENT INSTRUCTION, REV 2 OF THE SB, WHICH IS DUE OUT Q3 OF THIS YEAR, WILL INCLUDE THE DATA FOR T-FITTING REMOVAL AND INSTRUCTION TO CHANGE ANY CORRODED T-FITTINGS. CURRENTLY WE HAVE ORDERED AND RECEIVED BOTH OF THE T-FITTINGS FOR REPLACEMENT (PN 100T1440U3(LT) & 100T1440U4(RT).
