### TITLE: NACELLES/PYLON - INSPECT PYLON LOWER SPAR BETWEEN RIBS 9 AND 10 **CONF ALL MODIFICATIONS None REASON/DESCRIPTION/OPERATIONAL CONSEQUENCES On A/C fitted with GE and PW pylons, crack has been reported on pylon lower spar. The crack is running between ribs 9 and 10 and is starting on the center stiffener after the flat area. Some cracks have been reported re-initiating even after Service Bulletin embodiment. Hence a deeper investigation has been performed in order to propose the best solution possible to the operators. The aim of this Service Bulletin is to call for eddy current or liquid penetrant inspection of the pylon lower spar in order to detect any crack. This inspection will make it possible to detect crack propagation at an early stage, thus avoiding a significant repair and reduction of the structural capacity. New Flight Cycles / Flight Hours figures of Thresholds and Intervals, due to improvement of analyses and also consistent with in-service crack findings, were acknowledged by Airworthiness Authorities. NOTE: MSB 54-0079 does not cancel this inspection Service Bulletin anymore, there is a new inspection program after accomplishment of Service Bulletin No. A300-54-0079 Mod No. 10328S20412.
