New Aircraft Delays Keep Older Jets Flying, Filling Evergreen Aviation Technologies’ Maintenance Capacity

Preface

Global aircraft delivery delays are prompting airlines to keep existing planes in service for longer, supporting demand for inspections, parts replacement, and structural repairs. Evergreen Aviation Technologies (長榮航太, 2645-TW) is experiencing that demand directly: its four existing maintenance hangars are close to full capacity. Rather than relying on a new facility in the near term, the company plans to increase technician numbers, introduce a second shift, and shorten aircraft turnaround times. Its manufacturing business may also gain momentum from a new A321 fuselage-component program. This article examines the industry pressures behind the maintenance surge, the constraints that could limit growth, and the operational and manufacturing plans shaping the company’s outlook. The central issue is not simply rising demand, but how efficiently the available labor, parts, and facilities can convert that demand into completed work.

Lazy bag

Aircraft delivery delays are keeping older planes in service and driving maintenance requirements higher. Global aircraft orders awaiting delivery have exceeded 1.7萬架, while the average fleet age has risen to 15.1 years. Evergreen Aviation Technologies’ four hangars are nearing full capacity, so its near-term strategy centers on adding technicians, arranging a second shift, and improving turnaround. Parts shortages and limited repair capacity remain industry-wide constraints. Separately, the company’s Guanyin Plant 2 is expected to be completed in 2027年第二季 and begin production in 2027年第三季, supporting A321 fuselage-component work. Demand is strong, but labor, parts availability, and production schedules will determine how much can be delivered.

Main Body

Aircraft maintenance demand is being reinforced by a mismatch between airline fleet needs and the pace of new aircraft deliveries. According to data released this year by the International Air Transport Association (IATA), the global backlog of new aircraft orders awaiting delivery has exceeded 1.7萬架. At the same time, the average age of the global fleet has reached 15.1 years. When replacement aircraft arrive later than expected, airlines generally have to continue relying on aircraft already in operation. That extends the period during which those aircraft must be maintained and can increase requirements for scheduled checks, component replacement, and structural repairs.

This environment supports maintenance, repair, and overhaul (MRO) providers, but it does not guarantee that every company can immediately take on more work. Aircraft maintenance depends on specialized facilities, skilled personnel, and the timely availability of parts. A bottleneck in any one of these areas can delay a repair, hold an aircraft in a hangar for longer, and reduce the number of jobs a provider can complete. The industry’s challenge is therefore twofold: airlines need more maintenance, while service providers must find ways to expand throughput despite practical operating constraints.

Research published in June by IATA and Emerton identified continuing parts-supply and maintenance-capacity constraints for next-generation narrowbody engines, including LEAP and Pratt & Whitney GTF engines. These shortages matter because engine work and component availability can affect the duration of a maintenance visit. If required parts are not available when needed, a provider may be unable to complete a repair on schedule, even when the aircraft and maintenance team are ready. Longer turnaround times can in turn affect delivery commitments and limit a company’s ability to accept additional customer work.

Evergreen Aviation Technologies is already operating with limited room to expand through its current hangars. Its four existing hangars are close to full capacity, while a fifth hangar remains dependent on the allocation of land at Taoyuan Airport. As a result, the company’s maintenance approach for 2027 is expected to focus primarily on making better use of existing capacity rather than depending on a new facility. That makes operational execution especially important: increasing available labor and improving the flow of aircraft through existing facilities are central to expanding the number of maintenance jobs handled.

The company plans to supplement its workforce with additional technicians and arrange a second shift. These measures can increase the hours during which maintenance work is performed and help make more effective use of hangar space. However, staffing growth in aviation maintenance requires personnel with suitable technical skills, so hiring alone may not immediately translate into equivalent increases in completed work. Training, coordination among teams, and the availability of the parts needed for each job also influence how quickly additional labor can raise output.

Another part of the plan is to shorten the time aircraft spend entering and leaving maintenance facilities. A faster turnaround can release hangar space sooner, creating room for subsequent jobs without adding physical facilities. The benefit depends on careful planning: work scopes must be coordinated, parts must arrive on time, and maintenance tasks must be completed to the required standards. Efficiency improvements can help relieve capacity pressure, but they do not remove the underlying need for qualified staff, reliable supply chains, and suitable infrastructure.

International peers illustrate how higher demand can produce different financial outcomes. Lufthansa Technik reported that revenue increased 11% year on year in the first half of this year. However, material shortages, delivery delays, and foreign-exchange effects weighed on its results. Adjusted earnings before interest and taxes increased only 2%, and its margin fell to 7.1%. The figures show that a fuller order book or higher revenue does not automatically translate into equally strong earnings growth when input costs, delays, and other operating pressures persist.

ST Engineering reported a different pattern in its commercial aerospace division during the same period. Revenue increased 15% year on year, while earnings before interest and taxes rose 29%. The performance was attributed mainly to increased engine maintenance and spare-parts sales, along with improvements in product mix and production efficiency. Taken together, the two examples underline the importance of operational factors: companies serving a growing market may still see very different profit outcomes depending on the composition of their work, efficiency, and ability to manage supply constraints.

Evergreen Aviation Technologies also has a manufacturing initiative that may contribute to longer-term growth. Its Guanyin Plant 2 is expected to be completed in 2027年第二季, with production scheduled to begin in 2027年第三季. The facility is intended to produce A321 fuselage components. The timing means that this activity is not an immediate substitute for maintenance capacity; instead, it represents a separate manufacturing opportunity that depends on the new plant’s completion, production readiness, and customer schedules.

The market context for A321 components is supported by the composition of Airbus’s order backlog. In September, Airbus said that of the approximately 7,500 aircraft awaiting delivery in the A320 family, about 75% were A321 aircraft. This points to a substantial pipeline of potential demand for related components. Still, a large backlog does not by itself determine the timing or volume of orders received by an individual supplier. Evergreen Aviation Technologies’ future shipments will need to align with the new facility’s launch and the production schedules set by its customer.

Overall, the company’s outlook combines a near-term capacity-management challenge with a longer-term manufacturing opportunity. In maintenance, its immediate levers are staffing, shift arrangements, and faster aircraft turnaround, while the timing of a fifth hangar remains uncertain pending land allocation at Taoyuan Airport. In manufacturing, the A321 program offers a potential source of activity after Guanyin Plant 2 is completed and begins production. Across both businesses, the ability to execute plans will depend on labor availability, parts supply, facility readiness, and customer schedules. These are operational considerations, not guarantees of future financial results.

Industry data and company plans provide context for understanding demand and capacity, but they do not constitute investment advice. Investors should make independent assessments and carefully consider risks. No conclusion about future share-price performance follows solely from the demand indicators or planned production schedule described here.
