[pick] fleet-watch (Narrowbody fleet watch) angle#0
[pick] description: This week's lead angle: 737 MAX A320neo delivery delay backlog in the last 3 months. Also cover: CFM LEAP engine production durability fix in the last 3 months; Pratt Whitney GTF powder metal inspection groundings in the last 3 months; spare engine shortage lease rate narrowbody in the last 3 months. Framing — for a SA low-cost airline running a 737/A320 fleet — what does this mean for delivery slots, engine availability (LEAP/GTF), spare-engine cost, MRO turnaround, lease rates and effective capacity? Quantify AOG and cost impact where sources give numbers.. Emphasise developments and analysis from the last 3 months and bring a fresh angle distinct from a generic overview.
