Aviation Financing: How US Aviation Businesses Fund Aircraft, Parts, and Operations

Aviation financing is any capital structure a US aviation business uses to acquire aircraft, buy parts and avionics, fund MRO (maintenance, repair, and overhaul) work, or bridge the cash-flow gaps between billing and payment — ranging from long-term secured aircraft loans and operating leases to short-term, revenue-based working capital that approves on your bank deposits rather than your credit score. Which one fits depends on what you are buying and how predictable your revenue is: a hard asset with a long life (an airframe, a hangar, a shop machine) suits a term loan or lease amortized over years, while a timing problem — a large annual inspection you have to float, a parts order due before your customer pays, payroll during a slow winter — is usually better solved with fast working capital than with a multi-year note. This guide covers both, with the underwriting reality behind each.

What counts as aviation financing (and who needs it)

"Aviation financing" is a broad label because the industry is a stack of very different businesses, each with its own capital needs:

• Aircraft acquisition — Part 91 corporate operators, Part 135 charter companies, and flight schools financing the airframe itself, typically with a secured aircraft loan or a lease where the plane is the collateral.
• MRO and repair stations — FAA-certificated shops (Part 145) that need to buy inventory, tooling, and rotable parts, and often float labor on large jobs before the customer's invoice clears.
• FBOs and ground handling — fuel farms, ramp equipment, de-icing rigs, and seasonal working-capital swings.
• Flight schools and Part 141 academies — fleet expansion, engine reserves, and enrollment-driven cash flow that spikes and dips.
• Parts distributors and avionics installers — inventory-heavy businesses where cash is tied up on the shelf.

The mistake operators make is treating all of these as one financing problem. A $2.4M turboprop is an asset-backed decision. A $60,000 parts order you need to fulfill this week — with payment 45 days out — is a cash-flow decision. The right tool is different, and using the wrong one is expensive.

The main aviation financing options, and what each is actually for

Here is how a lender reads each structure, and where it fits:

• Secured aircraft loan (term loan). The plane is collateral; terms commonly run several years with amortization tied to the asset's useful life. Best for acquiring an aircraft you intend to keep and operate. Underwriting is slow and document-heavy — expect appraisals, logbook review, title and lien search, and often an escrow closing.
• Operating or capital lease. You use the aircraft or equipment without owning it outright (operating), or you finance-to-own (capital). Leasing preserves cash and can suit rapidly depreciating avionics or fleet aircraft you plan to cycle out.
• Equipment financing. For hangar equipment, ground-support gear, tooling, and shop machinery — the equipment secures the loan.
• SBA loans (7(a) / 504). Strong pricing and long terms for FBO real estate, hangar construction, or business acquisition. The tradeoff is time — weeks to months — and a heavy documentation burden. Not a fit when you need cash this week.
• Revenue-based financing / merchant cash advance marketplace. Approval is driven by your bank deposits and revenue history, not your credit score. Designed for working-capital timing gaps: floating a large annual inspection, buying an inventory lot, covering payroll in a slow season, or bridging to a customer payment. Repayment flexes with your cash flow rather than a fixed multi-year amortization.

Revenue-based financing for aviation working capital

Most aviation operators who search for financing don't actually need a five-year note — they need to solve a timing problem without draining their operating account. That is what revenue-based financing is built for.

Instead of underwriting your personal credit and demanding collateral, a revenue-based marketplace looks at the health of your business bank statements: consistent deposits, how many months of history, and the general trend. That makes it accessible to aviation businesses that are cash-flow strong but credit-imperfect — a common profile after a fleet expansion or a slow season.

Typical fit parameters for the marketplace we recommend: funding amounts starting around $10,000, FICO 500+ considered, and decisions in roughly 24-48 hours once bank statements are in. Repayment is structured as a share of revenue or a fixed periodic remittance, so it rises and falls closer to your cash flow than a rigid loan payment. This is not a guaranteed approval — nothing legitimate is — and it is not the tool for buying an airframe. It is the tool for keeping the doors open and the invoices flowing while a slow-moving asset lender takes its time.

Common aviation uses: floating a large annual or 100-hour inspection, stocking a rotable parts pool, covering ramp or shop payroll through a seasonal dip, or fulfilling a big parts/AOG order before the customer's net-30 or net-45 clears.

Decision framework: which aviation financing fits your situation

Match the tool to the problem. Here is the underwriter's shortcut:

A secured aircraft loan or lease works best when:

• You are buying a specific aircraft you intend to operate for years.
• The asset holds value and can serve as clean collateral (clear title, complete logbooks).
• You can wait weeks for appraisal, title search, and closing.
• You want the lowest cost of capital and predictable long-term payments.

SBA works best when: you are financing hangar real estate, construction, or a business acquisition, your credit and financials are strong, and time is not the constraint.

Revenue-based / MCA-marketplace working capital works best when:

• The need is a cash-flow timing gap, not a hard asset — inspection floats, inventory, payroll, AOG orders.
• Speed matters (you need a decision in days, not weeks).
• Your bank deposits are healthy even if your credit is imperfect.
• You want repayment that flexes with revenue instead of a fixed multi-year note.

Avoid revenue-based financing when:

• You are trying to buy the aircraft itself — the term and cost are wrong for a multi-year asset.
• Your revenue is thin or highly erratic; frequent remittances can strain an already-tight account.
• You have time and strong credit and can qualify for SBA or a bank term loan at a lower cost.
• You would be stacking it on top of existing advances without a clear payoff timeline.

See our merchant cash advance overview for a deeper read on when the cost of speed is worth paying.

Example scenarios: matching the tool to the need

These are illustrative profiles, not quotes. Figures are labeled "for example" to show how an operator would think through the decision — actual terms depend on your statements and the funder.

Notice the pattern: hard assets you keep go to loans and leases; cash tied up in time, labor, or inventory goes to revenue-based capital.

Documents and timeline: what to have ready

The single biggest cause of slow funding is a slow document package. What you need depends on the path:

For revenue-based working capital (fastest path):

• The most recent 3-6 months of business bank statements — the core of the decision.
• Basic business details (entity, time in operation, industry).
• Sometimes a voided check and a government ID.

With a clean statement package, decisions commonly come in 24-48 hours and funding shortly after. The lever you control is having statements ready and your deposits looking like the healthy business you are — minimize NSFs and keep revenue running through the account you submit.

For a secured aircraft loan or lease (slowest path):

• Aircraft logbooks and maintenance records (a gap in the logs can kill or delay a deal).
• Title and lien search, and often an escrow agent for closing.
• Appraisal or valuation.
• Business financials, tax returns, and sometimes a pre-buy inspection.

Plan on weeks, not days. If you have a timing-sensitive need running in parallel — say, payroll or a parts order that can't wait for the aircraft closing — that is exactly where short-term working capital bridges the gap.

How to protect your margins when you borrow

Underwriter's guidance, regardless of which tool you choose:

• Match the term to the asset's life. Don't finance a decade-long airframe with a short-term product, and don't tie up a quick inventory turn in a five-year note.
• Price the cost against the opportunity, not against a bank rate. Fast capital costs more than an SBA loan — but if it lets you take a job, fulfill an AOG order, or keep a crew, the return can justify it. If it only papers over a shrinking business, it won't.
• Don't stack blindly. Layering advances without a payoff plan is the fastest way to strangle cash flow. If you already carry an advance, understand your remittance load before adding another.
• Keep your bank statements clean. Your deposit history is your credit in the revenue-based world. Reduce overdrafts and route revenue through one primary account.
• Read the actual structure. Understand your remittance frequency and how it flexes. Anyone promising "guaranteed" approval before seeing your statements is not underwriting — they are selling.
