Appraisal: General Electric GE90 Family

The General Electric GE90 was developed to power the largest twin-engine commercial aircraft, the Boeing 777, initially delivering takeoff thrust of 97,300 lb. and later up to 115,500 lb. Its scale introduced logistical challenges, as the fan diameter makes transportation of a fully assembled engine impractical on most cargo aircraft. As a result, the GE90 was the first engine for which spares were optionally sold in a “spare propulsor” configuration, which excludes the fan section.

More than three decades after its introduction, the GE90 remains central to the long-haul fleet. This is occurring despite the impending service entry of the GE9X and increasing production of the Trent XWB. The GE90 market today is shaped by constrained new aircraft supply, strong long-haul demand, delayed fleet replacement and elevated fuel costs influenced by geopolitical developments.

Overview of the GE90 Engine Family

The GE90 entered service in the mid-1990s with 123-inch fan variants powering the 777-200 and 777-200ER. In the mid-2000s, larger 128-inch fan variants — the GE90-115 and GE90-110 — were introduced for the 777-300ER, 777-200LR and freighter variants. These larger variants now dominate the installed base, reflecting the commercial success of the 777-300ER and the 777 freighter.

Adoption of the GE90 accelerated in the mid- to late-2000s as fuel prices increased. Airlines replaced older four-engine aircraft with the more efficient 777-300ER and 777F. According to Cirium fleet data, over 2,600 GE90 engines are currently installed, with approximately 100 additional engines scheduled for delivery in the freighter production backlog.

The fleet is globally distributed, although approximately 25% is in the Middle East, which exceeds the region’s share of global capacity. Emirates, Qatar Airways and Saudia account for most of the fleet in this region. Despite this regional exposure, the GE90 fleet maintains broad global representation and liquidity across all major aviation markets.

Supply Constraints and Engine Availability

During the peak of the COVID-19 pandemic in early 2020, long-term storage of GE90-powered aircraft reached approximately 45 units. Increased aircraft teardown activity temporarily raised the supply of spare engines. However, this trend reversed as demand for widebody aircraft recovered and stored aircraft returned to service.

Engine availability has decreased significantly in recent years. Since mid-2023, overall storage rates have remained below 10%, based on Cirium Fleets Analyzer data, with some parked aircraft awaiting cargo conversion. Since 2023, public listings have typically included no more than one or two GE90 engines available for sale or lease at any given time, sometimes none.

Delays in certification of replacement aircraft, including the Boeing 777-9, combined with production constraints affecting the A350 program, have extended the operational lives of GE90-powered aircraft. At the same time, passenger-to-freighter conversion programs for the 777-300ER and 777-200LR continue to absorb aircraft that might otherwise have been retired. The IAI 777-300ERSF entered service in September 2025, with 10 aircraft delivered to date, while the Mammoth 777-200LRMF received Federal Aviation Administration certification in April 2026. Additional conversion variants are in development. These dynamics retain engines in active service for longer periods.

Market Values

Supply constraints have pushed Market Values upwards recently. Over the past year, GE90-115BL values have increased by 24%, reflecting strong demand for spares alongside rising maintenance and material costs and extended service lives. Current half-life Market Values for bare engines are approximately $19.9 million for the GE90-115BL and $9.3 million for the GE90-94B, in Cirium’s opinion.

Rising Fuel Costs

Limited availability of new-generation widebody aircraft continues to support value retention for the GE90. However, the type is exposed to rising fuel costs, particularly following recent geopolitical developments.

Airlines would typically seek to deploy more fuel-efficient aircraft, but supply constraints limit this option. At the same time, demand for direct long-haul flights has increased, particularly between Europe and Asia, as some passengers avoid connecting through Gulf hubs. Cirium schedules data indicates an 8% increase in available seat kilometers (ASK) between these regions in May 2026 compared with the same period in 2025. Higher fares on these long-haul routes partially offset increased fuel costs and support continued utilization of GE90-powered aircraft.

Flight tracking data from Cirium indicates a 12% reduction in utilization of the global 777-300ER fleet between May 2025 and May 2026. It remains unclear how much of this decline reflects temporary operational adjustments, particularly among Gulf carriers, versus longer-term trends. Sustained high fuel prices and reduced utilization could lead to increased retirements or freighter conversions. Aircraft teardown activity could increase the supply of spare engines, although there is currently no evidence of such a shift.

Cargo Market

Cargo operations play an important role in supporting long-term demand for the higher thrust, 128-inch variants of the GE90. The 777-200LRF, 777-200LRMF and 777-300ERSF provide significant long-range cargo capability. Passenger-to-freighter conversions further extend the service life of GE90 engines. This trend reinforces demand for maintenance services and spare engines, contributing to sustained market activity.

Maintenance and Durability

Maintenance considerations are central to operator decisions. The GE90-110 and GE90-115 are characterized by long on-wing intervals, with over 4,000 flight cycles between removals under typical conditions. Operations in harsher environments, particularly those involving high temperatures and particulate exposure, generally result in shorter intervals.

Full performance restoration costs range from approximately $17 to $20 million, depending on the scope of work and excluding replacement of life-limited parts. These costs encourage some operators to seek to acquire serviceable engines with remaining useful life rather than undertaking a full overhaul. Engines with well-documented maintenance histories and predictable exhaust gas temperature deterioration profiles are more attractive in the secondary market.

Outlook for the GE90 Market

The GE90 has built a reputation for durability and extended time‑on‑wing, particularly relative to some newer high‑thrust engines operating in comparable environments.

Although sustained higher fuel prices represent a potential threat, they are unlikely to significantly weaken demand in the near-term due to the absence of immediate alternatives. Stabilization of energy markets would reduce cost pressures and further support market conditions.
