AD FAA-2016-6671

We are adopting a new airworthiness directive (AD) for certain Airbus Model A300 B4-203 and A300 B4-2C airplanes. This AD was prompted by cracks found on pylon side panels (upper section) at rib 8. This AD requires a detailed inspection for crack indications of the pylon side panels; a high frequency eddy current (HFEC) inspection to confirm any crack indications; and repair of any cracking, or modification of the pylon side panels, and repetitive inspections and repair if necessary. We are issuing 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.
