MRO Lite – An MRO outlook from a quick-turn perspective

MRO Lite – An MRO outlook from a quick-turn perspective

By Asim Chalise, VP MRO Sales

Global passenger demand continues to rise. IATA figures show traffic up 5.3% year on year, with load factors remaining high. For airlines, this demand should be positive news. In reality, it is placing growing pressure on fleets, MROs, and the wider aviation supply chain.

Delays in new-generation aircraft and engine deliveries mean airlines have little choice but to keep older aircraft flying for longer. That gap between planned fleet renewal and actual delivery is now a defining feature of the market. And it comes at a cost.

Keeping ageing aircraft in service drives increased maintenance activity, greater parts consumption and workscope escalation. Turnaround times lengthen, and maintenance bills grow. Engines, in particular, are the biggest pressure point. A full shop visit for a CFM56-7B can cost between $5m and $7m. Even a limited performance restoration approaches $3.5m. For airlines already committed to significant capital spending on new aircraft or leases, funding second or third shop visits is becoming increasingly difficult to justify.

This strain is not limited to operators. Lessors, OEMs, MROs and suppliers are all part of the same system, working towards a shared objective: moving passengers safely, reliably, on time and within budget. It requires confident collaboration between operators, lessors, OEMs, MROs and suppliers. When one part of that system is stretched, the impact is felt across the entire ecosystem.

Against this backdrop, airlines and lessors are rethinking how they approach engine maintenance, taking a more progressive view of how engines are managed through the current cycle. Rather than defaulting to heavy shop visits, many are turning to more targeted solutions.

Module swaps are not a new concept, particularly on modular engines such as the CFM56. Different modules have different life limits, which naturally lends itself to selective replacement rather than full overhaul. Today, operators are increasingly opting to replace LLP-expired modules with green-time units to keep engines on wing while they wait for new aircraft or engine deliveries.

These “quick turn” or “hospital shop” visits focus on doing only what is necessary. The objective is not to reset the clock, but to treat the engine as a continued-time asset and extract maximum remaining value at the lowest possible cost and turnaround time. For many operators, this approach offers a pragmatic way to bridge the current gap.

Smaller, agile MROs are particularly well suited to this type of work. Their set-up and mindset allow them to deliver targeted workscopes efficiently, without the overhead costs associated with full overhaul programmes. As a result, quick-turn shop visit activity – what we refer to at AerFin as engine MRO Lite – and module swap strategies are becoming more prevalent across the market.

This shift does, however, raise important questions. If more operators pursue the same strategy, will there be sufficient green-time modules available to support it? And while module swaps are an effective short-term solution, they are not a long-term substitute for fleet renewal. Their value lies in buying time – long enough for deliveries to stabilise and capacity to return.

Looking ahead, the focus for AerFin’s engine shop is to scale existing capability and respond directly to market demand, continuing to progress our engine support offering. Combined with AerFin’s growing engine portfolio and material availability, this creates a powerful platform to support customers with cost-effective solutions such as end-of-lease inspections, top case repairs and module swap activity. That means becoming the shop customers ask for by name, while continuing to deliver cost-effective solutions such as end-of-lease inspections, top case repairs and module swap activity.

In a market defined by delay, cost pressure, and uncertainty, adaptability matters. Customers need partners they can rely on – organisations that respond confidently to changing conditions while continuing to move the industry forward. Targeted MRO is not about cutting corners – it is about making smart, informed decisions that keep fleets flying until the system catches up.
