News Room: The Shop Is Full and the Cash Is Not: What Independent Aviation Repair Stations Are Facing in 2026

An owner of an established independent aviation repair station gets a call from a regional operator, cargo carrier, flight school or business aviation customer. The customer has recurring engine or component work available and wants to know whether the shop can take it on.

At first, the opportunity appears to be a capacity question. The technicians are experienced. The shop has a good reputation. The customer needs work completed.

Then the owner runs the numbers.

The work itself is not necessarily the problem. The cash conversion cycle is.

Parts and materials must be purchased before the work can begin. Specialized tooling and test equipment may need to be added. The shop visit can extend for months, particularly when a component is waiting for inspection, repair, a replacement part or customer direction. In many cases, the operator pays only after the unit is returned, documented and accepted.

The repair station may have more work available than it can currently bill for, while cash remains tied up in parts, deposits and work in process.

That is the decision facing many independent Part 145 repair stations in 2026.

A growing market does not eliminate a cash-flow problem

The broader aviation maintenance market is expanding. Oliver Wyman's Global Fleet and MRO Market Forecast 2026-2036 places global MRO demand at approximately $136 billion in 2025 and projects it to reach nearly $198 billion by 2036, representing compound annual growth of about 3.7 percent.

That growth creates opportunity for independent repair stations. It also increases competition for technicians, parts, specialized equipment and working capital.

Oliver Wyman reports that approximately 41 percent of certified aviation mechanics in the United States are over age 60, with about 45,000 mechanics expected to retire during the next decade. The report also identifies a North American technician deficit forecast at approximately 19 percent by 2028.

At the same time, IATA has called for urgent action to address engine MRO bottlenecks, citing engine durability issues, spare parts shortages, limited spare engine availability and constrained aftermarket access. IBA, an aviation market intelligence firm, reports that LEAP engine turnaround times averaged an estimated 230 days gate to gate in 2025, while medium work scopes and quick turns averaged around 100 to 120 days.

Aviation Week has also reported on a high-pressure turbine blade supply crunch affecting CFM56 overhauls. When critical material is difficult to source, the shop may have available labor and hangar space but still be unable to complete and invoice the work.

For an independent repair station, market demand is helpful only if the business can carry the cost of fulfilling that demand.

Why the aviation repair cash cycle is unusually long

A typical service business may complete work and collect payment within a relatively short period. Aviation maintenance can be different.

The cash cycle may include:

Purchasing parts, consumables or used serviceable material before the customer pays.
Paying deposits to suppliers or securing limited inventory before a shop visit begins.
Carrying a unit through inspection, teardown, repair, testing and documentation.
Waiting for an outside repair vendor, OEM part or specialized process.
Completing the work and returning the unit to the operator.
Waiting for customer inspection, technical acceptance and final invoicing approval.
Managing warranty, rework or adjustment exposure after delivery.

Tooling and test equipment create another layer of timing pressure. The equipment may be necessary before the shop can accept additional work, but it does not immediately generate revenue on its own. The business pays for the asset first and hopes the added capability converts into completed, billable work over time.

That conversion is not automatic.

A repair station can add equipment and still have too much work sitting in process. It can purchase additional parts and still be unable to invoice because a required inspection, test or customer approval remains outstanding.

The important question is not simply whether demand exists. It is whether the shop can finance the period between paying for the work and collecting from the operator.

The three difficult choices

When the cash cycle is not addressed, the owner usually faces three imperfect options.

Decline the work.
The shop protects its cash, but the operator may place the work with another repair station. If the agreement involves recurring work or several aircraft, the opportunity may be difficult to recover.

Accept the work without sufficient preparation.
The shop may win the agreement but strain payroll, supplier relationships and day-to-day purchasing. A single delayed part or extended inspection can create pressure across the entire operation.

Turn down a larger agreement because the required tooling and inventory are not funded.
This can be the most frustrating outcome. The customer demand is real, the shop has relevant expertise and the work may fit the repair station's capabilities, but the business cannot carry the upfront cost.

The middle path is not automatically safe. Growth that consumes all available operating cash can leave a repair station less able to handle routine expenses, payroll, insurance, maintenance and unexpected rework.

A practical checklist before committing to more work

Before signing a recurring agreement or accepting a larger shop visit schedule, an owner should map the actual cash cycle rather than relying on a general estimate.

Consider these questions:

How many days pass from the first parts order to final cash collection?
Does the cycle begin with a customer deposit, or does the shop fund the early purchases?
When does the operator pay, and what event triggers payment?
Are progress payments available for long shop visits?
Who carries the cost of parts that are rejected, delayed or found unserviceable?
What is the true cost of the required tooling, inspection equipment, test equipment and shop machinery?
Will the equipment create additional billable capacity, or will it simply allow the shop to process more work in progress?
How much parts, rotable and consumable inventory must remain available?
Which items must be purchased in advance because they have long lead times?
How much operating cash must remain untouched during the transition?
Can payroll, insurance, rent, utilities and regular supplier payments continue if the operator's acceptance takes longer than expected?
What happens if the first few shop visits require more labor hours or rework than estimated?

The purpose of this exercise is not to discourage growth. It is to determine whether the agreement can be performed without creating a second problem while solving the first.

Inventory can be productive and still restrict the business

Parts inventory is necessary in aviation maintenance, but necessary does not mean liquid.

A component sitting on a shelf may be valuable, traceable and essential to a future repair. It may also represent cash that cannot be used for payroll or another supplier payment. If the part is specific to an aircraft platform, configuration or approved repair path, it may not be easily converted back into cash.

The same issue applies to work in process. A unit on the floor may represent substantial labor and material already invested, but it does not become operating cash until the work is completed, accepted and paid.

Industry reporting from AerFin describes the continuing pressure on engine MRO supply chains, including thin used serviceable material availability and parts shortages affecting CFM56 and other engine platforms. The result is a greater need for material planning, supplier coordination and disciplined inventory decisions.

For the repair station owner, the operational question is also a financing question: how much cash should be committed to inventory, and how much must remain available for the business around it?

Where financing may fit

Financing should not be used to justify work that does not make economic sense. It may, however, help an established repair station match capital structure to the timing of a legitimate expansion or operating requirement.

Equipment Financing

Equipment Financing may be relevant for specialized tooling, test and inspection equipment, ground support equipment and shop machinery. Potential capacity may range from approximately $5,000 to $25MM or more, with terms potentially extending up to 84 months and up to 100 percent financing where applicable.

Structure depends on the asset, the transaction and qualification. The goal is to avoid forcing a long-use productive asset to compete directly with monthly operating cash.

Working Capital

Working Capital may be relevant to the legitimate cash-flow timing gap created by parts and material purchases, payroll and deposits before operator payment arrives. Potential capacity may range from approximately $50,000 to $10MM, with terms potentially extending up to 24 months.

Well-qualified businesses may qualify for more attractive working capital structures than common high-cost short-term market products. For other businesses, structure and cost depend on credit history, cash flow, time in business, transaction structure and risk.

Financing for Materials, Payroll, Bonds & Insurance can also be relevant for project-driven commercial work where it fits, although aviation repair work should be evaluated according to its own contract, billing and repayment characteristics.

Simplified Capital provides access to capital and commercial financing solutions through an individual transaction review. The company is not a direct lender and does not use one structure for every business.

The decision is whether the cash cycle can support the opportunity

The strongest opportunity is not always the largest agreement. It is the agreement the repair station can perform while protecting quality, payroll, supplier relationships and operating reserves.

An owner considering additional operator work should be able to answer three questions:

What cash must be committed before the first invoice can be collected?
How long can that cash remain tied up if parts, testing or customer acceptance take longer than planned?
Can the shop add the required capacity without weakening the rest of the business?

If the answers support the economics of the work, the next step is determining whether equipment financing, working capital or another commercial financing structure can match the shop's real cash cycle.

Simplified Capital has served business owners since 2002 and is A+ Rated with the BBB since 2003.

The reason to start a conversation is straightforward. An owner can get a realistic read on whether added capacity and inventory can be funded in a way that matches the repair station's actual cash cycle before committing to the agreement.
