The LEAP-1A Engine Aftermarket Crisis: Global Non-Availability & Strategic Solutions
The LEAP-1A Engine Aftermarket Crisis: Global Non-Availability and Strategic Solutions for A320neo Operators
A comprehensive analysis of supply chain bottlenecks, MRO constraints, extended shop visit turnaround times, and actionable strategies for navigating the LEAP-1A shortage.
Contents
Crisis Overview
For operators of the Airbus A320neo family, the CFM International LEAP-1A engine has become a focal point of industry-wide concern. The global aftermarket for LEAP-1A engines is experiencing unprecedented constraints, with spare engine availability at near-zero levels and shop visit turnaround times extended by 100–150% compared to pre-crisis benchmarks.
According to industry data from IBA, Cirium, and Oliver Wyman, the aftermarket pool of serviceable LEAP-1A engines remains severely depleted. Operators are increasingly relying on expensive short-term lease arrangements, asset pooling strategies, and in some cases grounding aircraft to manage fleet plans. This report examines the root causes of the crisis, its operational and financial implications, and actionable strategies for mitigation.
Root Causes of the Non-Availability Crisis
Five primary factors have converged to create the current LEAP-1A aftermarket environment:
- OEM production prioritization. CFM International has concentrated manufacturing capacity on new engine deliveries for Airbus, leaving limited resources for spare engine inventory.
- Durability challenges. Early operational experience revealed higher-than-expected wear in hot-section components, particularly in harsh environments, driving increased shop visit rates.
- Supply chain bottlenecks. Critical component shortages and extended lead times for durability upgrade kits (HPT kits) have constrained MRO output.
- Extended turnaround times. Overhaul induction times have increased significantly, with some facilities experiencing backlogs of six to nine months.
- Post-pandemic utilization. A320neo fleets are operating at record utilization rates, accelerating time-on-wing consumption and bringing forward shop visit requirements.
Market Snapshot
| Metric | Current Status |
|---|---|
| Spare engine availability | Extremely limited / near zero |
| Lease rate environment | Record high / seven-figure monthly reports |
| MRO capacity | Constrained / multi-month backlogs |
| LLP and module demand | High / extended lead times |
| Shop visit turnaround time | Extended (120–180+ days typical) |
LEAP-1A vs PW1100G: A320neo Engine Options
Airbus A320neo operators face a choice between the CFM LEAP-1A and the Pratt & Whitney PW1100G (GTF). Both engines have experienced durability and aftermarket challenges, but the nature and severity differ. Understanding these differences is critical for fleet planning and asset strategy.
| Metric | LEAP-1A | PW1100G (GTF) |
|---|---|---|
| Fuel efficiency | ~15-20% vs CFM56 | Similar / comparable |
| Installed base (A320neo) | Larger (~55% of fleet) | Smaller (~45%) |
| Primary durability issue | HPT wear, combustor | High-pressure compressor, bearing |
| Current aftermarket availability | Extremely limited | Limited but improving |
| Shop visit TAT | 120-180+ days | 100-150 days |
For operators considering fleet transitions, understanding LEAP-1A vs PW1100G availability, maintenance costs, and lease rates is essential. Safe Fly Aviation advises clients on both platforms.
Operational and Financial Impact
Extended grounding periods for A320neo aircraft awaiting spare engines, leading to schedule disruptions and revenue loss.
Industry reports suggest lease rates for available LEAP-1A spare engines have increased substantially, with some transactions reportedly exceeding seven figures per month.
Airbus has acknowledged engine supply constraints affecting A320neo family delivery timelines.
Operators are increasingly forced into expensive short-term lease arrangements from specialized lessors.
Impact on Aircraft Lessors
The LEAP-1A shortage is reshaping the lessor landscape. Major lessors including AerCap, Avolon, SMBC, and BOC Aviation are navigating several challenges:
- Lease extensions: Operators are requesting extensions on existing LEAP-1A-powered aircraft rather than returning them.
- Reserve adjustments: Maintenance reserve rates are being renegotiated to reflect higher shop visit costs.
- Remarketing delays: Returning aircraft require spare engines that are not available, delaying redelivery.
- Spare engine acquisitions: Lessors are actively acquiring LEAP-1A engines and LLP packages to support their portfolios.
Safe Fly Aviation works with lessors to source spare engines, manage end-of-lease returns, and facilitate asset remarketing.
Shop Visit and Turnaround Timeline
| Metric | Pre-crisis (2022–23) | Current (2026) | Change |
|---|---|---|---|
| Standard shop visit TAT | 60–90 days | 120–180+ days | +100–150% |
| Hot section inspection TAT | 45–60 days | 90–120 days | Significant increase |
| Spare engine availability | Moderate | Near zero | Severe constraint |
| HPT kit lead time | 3–4 months | 6–9 months | Extended delays |
Strategic Mitigation for Operators
Based on Safe Fly Aviation's work with global operators, we recommend a multi-pronged approach:
- Enhanced predictive monitoring. Leverage health data analytics to optimize on-wing time and forecast shop visits accurately.
- Diversified MRO partnerships. Build relationships with multiple certified facilities, including emerging players in Asia and the Middle East.
- Asset pooling and leasing. Participate in engine pooling programs. Safe Fly Aviation can assist in identifying available spare assets.
- Durability upgrade acceleration. Accelerate incorporation of CFM's HPT durability kits to reduce future shop visit frequency.
- LEAP-1A engine acquisition. For operators seeking to acquire spare engines, modules, or LLP packages, Safe Fly Aviation provides sourcing support and transaction advisory.

Market Outlook and Recovery Timeline
CFM International continues to make progress. More than 1,200 HPT durability kits have been shipped globally, with significant fleet-wide implementation underway. MRO capacity is expanding with new facilities coming online in Europe, Asia, and the Americas. By 2027–2028, operators can expect improved spare engine availability and normalized shop visit turnaround times.
However, full market stabilization is not expected before late 2027 or 2028. Operators who act decisively today—through strategic planning, technology adoption, and strong industry partnerships—will be best positioned to weather the current constraints. For lessors and operators holding LEAP-1A assets, current market conditions present a favorable environment for lease placements and strategic acquisitions.
