WASHINGTON, D.C. - The Federal Aviation Administration (FAA) has issued a new airworthiness directive expanding inspection requirements for CFM International Leap-1A engines to include those operating in South Asia. This regulatory action responds to data indicating that these engines, which power Airbus A320neo jets, suffer from the same dust-induced turbine blade cracks and accelerated deterioration previously identified in Middle Eastern operations. Effective in 16 days, the order mandates specific borescope inspections for high-pressure turbine blades; however, the FAA notes that no US-registered aircraft are currently affected by this directive.
CFM International characterizes the situation as a known issue, stating that operators have already been complying with previously issued service bulletins to prevent operational disruptions. The problem arises from the engine's high-efficiency design, which runs at higher temperatures and pressures, making internal components more vulnerable to distress in dusty environments. To mitigate these failures, CFM has developed a durability kit featuring redesigned components, with approximately one-third of the global Leap-1A fleet already updated with the new configuration.
