EASA AD US-2025-12-08
Turbine Engine - Combustion Chamber Assembly - Inspection
The Federal Aviation Administration's Airworthiness Directive 2025-12-08 addresses certain General Electric Company CF34-8 series engines, including models CF34-8C1 through CF34-8E6A1. This directive mandates inspections of the combustion chamber assembly (CCA) forward flange using fluorescent penetrant inspection (FPI) techniques to detect potential cracks and requires replacement if necessary. The AD aims to mitigate a predicted reduction in the cyclic life of the CCA forward flange to ensure continued airworthiness.
