### TITLE: NACELLES/PYLON - INSPECT PYLON LOWER SPAR BETWEEN RIBS 9 AND 10. **CONF ALL MODIFICATIONS None REASON/DESCRIPTION/OPERATIONAL CONSEQUENCES On aircraft fitted with PRATT & WHITHNEY pylon, 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. This Inspection Service Bulletin was first modified in the frame of the A310 Aircraft Extended Service Goal study, but some cracks have been reported re-initiating even after Service Bulletin embodiment. Hence a deeper investigation has been performed on order to propose the best alternative solution to the operators. This Inspection Service Bulletin requires an Eddy current or a 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 Threshold and Intervals, due to improvement of analyses and also consistent with in-service crack findings, were acknowledge by Airworthiness Authorities.
