Engine shop-visit queues become the industry’s defining constraint of the second half
Airframers can raise rate; the hot section cannot follow at the same speed. That gap now sets the delivery calendar for everyone.

Halfway through the year the picture has clarified: the constraint on aircraft deliveries is no longer fuselage or wing capacity but propulsion. Airframers have demonstrated they can lift assembly rate, yet engine availability and overhaul throughput have not kept pace, and the queue for hot-section shop visits now stretches well into next year across every major type.
The mechanics are unforgiving. A hot-section overhaul needs qualified capacity, certified tooling and scarce parts, and none of those scale quickly. Where inspection campaigns pulled forward demand, the backlog compounded, leaving operators waiting for slots on engines already off wing. Lessors report the same story from the other side: serviceable spare engines command a premium unheard of five years ago.
For airlines the practical consequence is planning conservatism — holding older aircraft longer, leasing replacement lift, and building schedule buffers around aircraft-on-ground risk. For suppliers with qualified overhaul capacity, it is the strongest pricing environment in memory.
Our read: watch shop-visit turnaround times rather than order announcements. They are the honest measure of when the industry can actually deliver what it has already sold.
