AOG & Fleet Grounding Watch
Intelligence directory tracking commercial airline sub-fleets grounded for mandatory regulatory airworthiness directives (ADs), engine durability inspections, and supply chain MRO shop visit holds.
Grounded Sub-Fleets: 895 Jets Estimated Leading Campaign: P&W GTF Powder Metallurgy (PW1100G) Average Wing Downtime: 120 to 280 Days Status: Active MRO Monitoring
Fleet Grounding Highlights
- Monitoring 895 commercial passenger aircraft globally affected by mandatory airworthiness directives and engine shop visit queues.
- Primary disruption driver is the Pratt & Whitney PW1100G GTF powder metallurgy inspection campaign affecting over 600 A320neo family jets.
- Average wing-off downtime ranges from 90 to 280 days due to global MRO titanium disk and turbine blade supply chain bottlenecks.
- Airlines lease supplementary classic aircraft (A320ceo, 737-800) to maintain scheduled network capacity while engines undergo shop visits.
