Airworthiness Directives; General Electric Aircraft Engines CF34 Series Turbofan Engines

The US Federal Aviation Administration (FAA) has issued a new airworthiness directive (AD) for General Electric Aircraft Engines CF34 series turbofan engines, requiring inspections and replacement of high-pressure compressor (HPC) spools and disks to prevent engine failure and aircraft damage. The directive is prompted by a cyclic life analysis revealing increased stress levels due to manufacturing discrepancies.
