Infrastructure Briefing — October 4, 2025
Pratt & Whitney's 2023–2026 GTF powder-metal inspection campaign will pull 600–700 PW1100G-JM engines from service, creating multi-month RMA and shop-visit backlogs airlines must plan around.
What happened: RTX disclosed that microscopic contamination in certain Pratt & Whitney geared turbofan (GTF) disks requires accelerated inspections of 600–700 PW1100G-JM engines between 2023 and 2026, with as many as 350 aircraft expected to be grounded during peak shop visits.RTX fleet update
Why it matters: Each removal consumes scarce module inventory and shop capacity, driving multi-month RMA queues and forcing airlines to rebalance spare-engine pools. Operators with limited spare ratios face extended aircraft-on-ground time unless they pre-approve leasing or green-time swaps.
Actions for fleet and supply managers
- Book slots and parts early. Coordinate long-lead shop visits with Pratt & Whitney and MRO partners; secure module allocations before scheduled removals and track estimated turnaround times.
- Model spare exposure. Use fleet availability scenarios that include 250–300 day turn times cited by operators to plan wet leases, ACMI cover, or utilization shifts while engines are in queue.Operator disclosures
- Preserve chain of custody. Document serial numbers, borescope results, and shipping records for every RMA to protect warranty claims and resale value when refurbished engines return to service.
