Delta Air Lines has announced an expansion of its maintenance, repair and overhaul (MRO) capabilities, becoming the first and only North American carrier licensed to support both the CFM LEAP-1A and CFM LEAP-1B. Delta TechOps joined CFM International’s MRO network back in 2022 with the Boeing 737 MAX’s LEAP-1B engine, before achieving full LEAP capability with the LEAP-1A this month.
