EASA Mandates 7,800-Cycle Inspection for Boeing 787 Engines

The European Union Aviation Safety Agency (EASA) has issued a new Airworthiness Directive AD 2026-0117R1 requiring mandatory inspections of critical low-pressure turbine discs on Boeing 787 engines after 7,800 flight cycles, overriding Rolls-Royce's promise of six-year maintenance intervals.

Why it matters. Airlines operating Boeing 787 Dreamliners will need to adjust their maintenance schedules, potentially increasing costs and operational complexity.
