Through 2028 and 2029, the number of new-generation engines in both the narrowbody and widebody fleets is expected to surpass that of current and older-generation models.
That is what Aviation Week Network Commercial Fleet & MRO Forecast 2025 predicts, although it assumes no additional production disruption and that new aircraft output continues to ramp up.
In the meantime, though, demand for current-generation engines is expected to remain strong, probably for another two years. What this will mean for the aftermarket is analyzed in the recently published Engine Yearbook 2025, which includes the best of Aviation Week Network’s commercial and business jet engines reporting over the past year as well as many specially commissioned features.
This year’s maintenance section contains thorough analysis of Aviation Week Network’s latest forecast data for the engine fleet and aftermarket, plus features on auxiliary power unit (APU) repairs; engine maintenance capacity and turnaround times; sourcing business jet engine parts; and an update on Pratt & Whitney Geared Turbofan inspections.
On engine technology, we examine why Boeing may be cooling on plans for an open rotor to power its next narrowbody; how Rolls-Royce is progressing with Trent improvements and its Pearl engine program; how OEMs are achieving durability and efficiency for turbine blades; Airbus’ strides in hydrogen propulsion; and the potential for electric aircraft on regional routes.
Engine financiers, meanwhile, should look out for an exclusive Q&A with Engine Lease Finance Corporation boss Richard Hough, plus new interviews with TrueAero and aviation venture capital investor RTX Ventures.
There is also a look at the value of vertical integration for engine lessors, plus, as always, exhaustive directories of all the world’s engine and APU overhaul and repair providers.
