### TITLE: NACELLES/PYLONS - INSPECTION OF PYLON FUEL DRAIN PIPE AT LOWER AFT PYLON FAIRING (LAPF) **CONF ALL MODIFICATIONS None REASON/DESCRIPTION/OPERATIONAL CONSEQUENCES In a reported event, a pylon fuel drain pipe was found cracked without fuel leakage in the pylon. The damage was caused by overlength screws securing the Lower Aft Pylon Fairing (LAPF). As a single failure, this event has no operational repercussion but the damage is not easily visible and there is no maintenance check of the pylon fuel drain pipe. The failure highlighted in this event could have been combined with fuel leakage in the pylon normally drained by this pipe. Without appropriate drainage this could lead to an accumulation of fuel in the lowest point of the LAPF. When high temperatures are present within the LAPF, and without ventilation, an unsafe condition could develop by potential fuel leakage igniting and resulting in fire. This Service Bulletin requires inspection of the fuel drain pipe in the pylons, replacement of the pipe as necessary and replacement of overlength screws. Accomplishment of this Service Bulletin will ensure appropriate pylon drainage in case of a potential fuel leak. GENERAL EVALUATION EVALUATION TABLE COMPLIANCE MANDATORY (1) CANCELS INSPECTION SB NO POTENTIAL AD YES A/C OPERATION AFFECTED NO RELIABILITY AFFECTED NO PAX COMFORT AFFECTED NO COST SAVING NO ETOPS AFFECTED NO STRUCTURAL LIFE EXTN NO VENDOR SB INVOLVED NO NOTE (1): Service Bulletin must be accomplished.
