Widebody Engine Overhaul Costs $3M–$8M and Can Exceed $10M Once Logistics, Spares, Labor and Downtime Are Counted
Why It MattersOverhaul bills now hinge on shop turnaround and downtime as much as on parts, so spare-engine availability and shop capacity increasingly set operators' real cost of keeping widebodies flying.
A widebody engine overhaul costs about $3 million to $8 million or more, with repairs to the General Electric GE90 that powers the Boeing 777 at the high end of that range. Once parts, labor, freight and idle aircraft are counted, a single event can pass $10 million.
The cost breaks into five areas. Removal, handling and installation of an engine costs $8,000 to $30,000 per event. A matching engine stand rents for $1,000 to $3,000 per day, road transport on air-ride low-boy trailers costs $3,000 to $8,000 per trip, and air freight costs $10,000 to $50,000 for standard transport and can exceed $150,000 in an emergency. Insurance of 0.2% to 0.5% of declared value, on engines valued at $15 million to $35 million or more, adds $20,000 to $50,000 per one-way journey.
Spare engine leasing typically runs $3,500 to $6,500 a day and can top $10,000 for newer engines. Shop turnaround, historically 60 to 90 days, has stretched to 150, 200 or even 300 days amid supply chain bottlenecks, parts shortages and labor constraints. At $5,000 a day, a 200-day stay adds $1,000,000 in leasing costs. During the Trent 1000 crisis, Rolls-Royce began inspecting 383 Package C engines after two Air New Zealand incidents, and by June 2018 almost 50 Boeing 787s were grounded awaiting engines. Shop labor is also rising: six large US airline operations saw labor and materials spending rise 68% between 2019 and 2025, while flying hours rose only 10%.
Lost aircraft utilization adds further cost. Norwegian Air Shuttle's Trent 1000 blade durability problems on its Boeing 787s cost it $120 million in passenger compensation alone and forced it to charter fuel-inefficient aircraft including the Airbus A380 and older Boeing 747s.
Life-limited parts, the rotating components such as discs and shafts that may fly only a fixed number of cycles, are the fifth area. A full set for a widebody engine usually costs more than a complete performance restoration, which is how a heavy GE90, GEnx or Trent visit reaches $10 million or more. High-time GE90s trade between $4.2 million and $7.8 million depending on cycles remaining.
