## Summary

We propose to adopt a new airworthiness directive (AD) for certain Airbus Model A300B4-203 and A300B4-2C airplanes. This proposed AD was prompted by cracks found on pylon side panels (upper section) at rib 8. This proposed AD would require a detailed inspection for crack indications of the pylon side panels, a high frequency eddy current (HFEC) inspection to confirm any crack indications, modification of the pylon side panels, and repetitive inspections and repair if necessary. We are proposing this AD to detect and correct cracking of the pylon side panels. Such cracking could result in pylon structural failure and in-flight loss of an engine.
