Engine Overhaul Financing: Ways to Pay for an Overhaul, With Payment Examples
This guide is for owners with an overhaul coming due, or already quoted, who need to decide how to pay for it. It compares the funding options, shows computed payments on $35,000 and $60,000, and covers what lenders ask for.
How much will you actually need to finance?
Start from the all-in number, not the headline overhaul price. Overhaul pricing varies widely by engine model, overhaul type and shop. If you're still choosing between a field overhaul, a factory rebuild and a new engine, read field overhaul vs factory rebuilt vs new first. Then build the budget line by line:
- Overhaul or exchange price, including any core charge if your old engine turns out to be unserviceable.
- Removal and reinstallation labor, plus shipping or crating if the engine goes to a distant shop.
- Accessories not in the quote: magnetos, carburetor or fuel servo, starter, alternator, oil cooler, vacuum pump.
- Firewall-forward odds and ends: hoses, baffles, engine mount inspection and repair, exhaust work.
- The propeller. With the engine off, many owners overhaul the prop at the same time. Budget for it separately.
- A contingency of about 10% for findings once the engine is apart, such as a crankcase, crankshaft or cam that fails inspection.
| Line item | Four-cylinder example | Six-cylinder example |
|---|---|---|
| Overhaul or exchange quote | $40,000 | $62,000 |
| Removal and reinstallation | $3,000 | $5,000 |
| Accessories, hoses, baffles, shipping | $2,000 | $3,000 |
| 10% contingency | $4,500 | $7,000 |
| All-in budget | $49,500 | $77,000 |
| Paid from reserves or cash | $14,500 | $17,000 |
| Amount to finance | $35,000 | $60,000 |
Every hour-based reserve you've set aside reduces the borrowing. If you haven't set one up, the SMOH and TBO guide shows the reserve-per-hour math for the next engine.
What are the ways to pay for an engine overhaul?
| Option | Collateral | Typical term | Cost vs other options | Main watch-out |
|---|---|---|---|---|
| Cash-out refinance of an existing aircraft loan | Aircraft | Up to 20 yrs for singles on loans of $75k+; 10–15 yrs for twins (AOPA) | Usually lowest rate | Replaces your current loan and its rate. Appraisal and 2–4 weeks to close |
| New aircraft-secured loan on a paid-off aircraft | Aircraft | Same ranges, driven by loan size | Usually lowest rate | Puts a lien on a free-and-clear aircraft. Lender sets insurance requirements |
| Shop or manufacturer financing program | Varies by program | Varies by program | Varies; compare the APR | Availability and terms change. Read fees, prepayment terms and who holds the lien |
| Unsecured personal loan | None | Usually short | Usually higher than secured | Higher payment from the short term. Loan size limits |
| HELOC or home-equity loan | Your home | Varies | Often competitive; HELOCs are usually variable | Your house secures an aircraft expense. Rate resets on variable lines |
| Cash reserves | n/a | n/a | No interest; opportunity cost only | Don't drain the emergency fund you need for the next squawk |
Cash-out refinance or new aircraft-secured loan
Aircraft lenders lend against the aircraft, so the overhaul usually rides on the aircraft loan itself. AOPA Aviation Finance describes it plainly: aircraft lenders "use the aircraft itself as collateral for the loan, so any financing currently in place would need to be refinanced into a new loan to include the overhaul" (AOPA, 2023). AOPA also says aircraft lenders "will generally add value" for major engine overhauls (AOPA), so the appraisal can reflect the fresh engine. Expect the lender to size the loan against a post-overhaul appraisal. Ask whether it will fund before the work is finished, at completion, or only after the logbook entry is made. Our refinancing guide covers the refinance steps.
Shop and manufacturer programs
Some engine shops and manufacturers have offered financing or deferred-payment programs, usually through a third-party lender. Availability, rates and eligibility change often, so treat any program as one quote among several. Before signing, get the APR (not just a promotional rate), the term, all fees, the prepayment terms, what happens when a promotional period ends, and whether a lien is filed against the aircraft or engine. If you already have an aircraft loan, check whether your security agreement allows another lien. Many don't without the lender's consent.
Personal loans and home equity
An unsecured personal loan keeps your aircraft loan and its rate intact and can fund quickly. The trade-off is usually a higher rate, a shorter term and a larger monthly payment. Home-equity borrowing can price well, but your house secures an aircraft expense, and HELOC rates are usually variable. Don't assume the interest is deductible. Ask a CPA how it applies to your situation.
What do payments look like on a $35,000 or $60,000 overhaul?
The tables below are computed, not estimated. The rates span the range major aviation lenders quoted for piston aircraft as of September 2026 (AOPA lists 6.99% to 9.99%; FLYING Finance lists certified-piston rates from 7.01%). Unsecured personal loans may price above this range.
| Term | 7.00% APR | 8.50% APR | 10.00% APR |
|---|---|---|---|
| 5 years (60 mo) | $693/mo $6,583 interest | $718/mo $8,085 interest | $744/mo $9,619 interest |
| 7 years (84 mo) | $528/mo $9,372 interest | $554/mo $11,559 interest | $581/mo $13,807 interest |
| 10 years (120 mo) | $406/mo $13,766 interest | $434/mo $17,074 interest | $463/mo $20,503 interest |
Loan amount $35,000. Principal and interest only; excludes insurance, taxes and fees. Illustrative, not a quote.
| Term | 7.00% APR | 8.50% APR | 10.00% APR |
|---|---|---|---|
| 5 years (60 mo) | $1,188/mo $11,284 interest | $1,231/mo $13,860 interest | $1,275/mo $16,489 interest |
| 7 years (84 mo) | $906/mo $16,067 interest | $950/mo $19,816 interest | $996/mo $23,670 interest |
| 10 years (120 mo) | $697/mo $23,598 interest | $744/mo $29,270 interest | $793/mo $35,149 interest |
Loan amount $60,000. Principal and interest only; excludes insurance, taxes and fees. Illustrative, not a quote.
Stretching the $35,000 loan from 5 to 10 years at 8.5% cuts the payment from $718 to $434. It also more than doubles total interest, from $8,085 to $17,074. An engine you'll fly for a decade can justify a longer term. One you'll sell in three years probably can't.
Cash-out refinance vs a separate shorter loan: a worked comparison
An owner owes $70,000 on a single with 12 years left at 7.25% ($729 a month) and needs $60,000 for an overhaul. The as-overhauled appraisal comes in at $190,000. The rates below are illustrative picks within the September 2026 range.
| Keep existing loan + separate 7-yr loan at 8.5% | Cash-out refinance: $130,000, 20 yrs at 7.5% | |
|---|---|---|
| Monthly payment | $1,679 for 7 years, then $729 | $1,047 for 20 years |
| Interest on the overhaul portion | $19,816 | About $56,005 if carried the full 20 years |
| Total paid, both loans combined | $184,825 | $251,345 |
| Loan-to-value | n/a (the separate loan may be unsecured) | 68% of the as-overhauled appraisal |
The refinance lowers the monthly outlay by $632 during the first seven years. Carried to term, though, it costs $66,520 more, because it stretches both the old balance and the overhaul over 20 years. It also gives up the older 7.25% rate. If the refinance has no prepayment penalty, a middle path is to take the long term for cash-flow safety and prepay aggressively. A standalone $60,000 loan would not qualify for a 20-year term on its own: AOPA's lenders reserve 20 years for single-engine loans of $75,000 or more.

How do lenders qualify an overhaul loan?
For an aircraft-secured overhaul loan or refinance, expect to provide:
- Credit and income: most aviation lenders look for 680+, with the best pricing typically from around 720 to 730. Lenders also look at existing debt and liquid reserves. See credit score requirements.
- A written overhaul quote or work order naming the shop, the engine model and serial number, the overhaul type and what's included.
- Logbooks and an appraisal. The appraisal may be done "as is" and "as completed". Engine time is one of the biggest value adjustments, so the fresh overhaul should show up in the as-completed figure. See how appraisals affect loan terms.
- Insurance naming the lender as required, usually as loss payee on hull coverage.
- A funding plan that lines up the shop's deposit and completion payments with when the lender actually disburses.
As a timeline guide: pre-qualification through a financing specialist typically takes 1 to 3 business days. An aircraft-secured loan or refinance generally closes 2 to 4 weeks from application once the appraisal and documents are in. Start before the engine comes off, not after.
Which option fits which situation?
- Existing loan at a rate well below today's: keep it. Fund the overhaul from reserves plus a shorter separate loan, if your security agreement allows it.
- Existing loan at or above today's rates, or a paid-off aircraft: an aircraft-secured refinance or new loan usually gives the lowest rate and the most term flexibility.
- You need the money in days, not weeks: a personal loan or existing credit line bridges the gap. Consider refinancing into a secured loan later.
- You're selling within about two years: price the overhaul against resale first. See how engine time affects aircraft value.
- Twin or aircraft built before 1960: expect shorter maximum terms or a larger equity requirement. Ask early.
Is an engine overhaul tax-deductible?
For a business-use aircraft, an overhaul may be deducted as a repair or capitalized and depreciated, depending on the facts and how the work is characterized. The answer affects your after-tax cost, so confirm the treatment with a CPA or aviation tax advisor before you schedule the work. See our aircraft depreciation guide for the general rules.

Frequently asked questions
Can you finance an aircraft engine overhaul?
Yes. The most common route is an aircraft-secured loan: AOPA Aviation Finance notes that because lenders use the aircraft itself as collateral, any existing loan usually has to be refinanced into a new loan that includes the overhaul. Other routes are shop or manufacturer programs, unsecured personal loans and home-equity borrowing. Each trades rate against speed, term length and what you pledge as collateral.
What credit score do I need to finance an engine overhaul?
There is no universal minimum, but most aviation lenders look for 680 or higher, and the best pricing typically starts around 720 to 730. Lenders also review income, existing debts, cash reserves and the aircraft itself, including an appraisal that reflects the overhaul. Unsecured personal lenders lean more heavily on credit score and income because there is no aircraft collateral behind the loan.
Is a cash-out refinance or a personal loan better for an overhaul?
A cash-out refinance usually carries a lower rate and a longer term because the aircraft secures it, but it replaces your existing loan and takes weeks to close. A personal loan leaves your aircraft loan untouched and funds faster, but typically costs more and runs for a shorter term. Compare total interest and the monthly payment, not the rate alone.
How long can I finance an engine overhaul?
It depends on the structure. If the overhaul is rolled into an aircraft loan, AOPA's lenders offer single-engine terms of 5 to 20 years, with 20 years only on loans of $75,000 or more. Twins are limited to 10 to 15 years. Standalone unsecured loans for the overhaul alone usually run much shorter. Longer terms lower the payment but raise total interest.
What is the monthly payment on a $60,000 engine overhaul loan?
At 8.5% APR, a $60,000 loan costs about $950 a month over 7 years or $744 over 10 years, principal and interest only. At 7% over 10 years it is about $697. Rates for piston aircraft loans quoted by major aviation lenders ran roughly 7% to 10% as of September 2026. Your rate depends on credit, collateral and term.
Will the lender pay the engine shop directly?
Often, but the timing varies. Many shops want a deposit when they book the slot or order the engine, and the balance when the work is done. Lenders may fund only at closing or completion, against an invoice and the logbook entry. Ask both sides for their payment schedules before you sign, and plan to cover any deposit from cash.
Should I overhaul or sell the airplane with a run-out engine?
If you plan to keep the airplane for several more years, overhauling usually makes sense, because you get the engine's full value in flying. If you're selling soon, buyers typically price a run-out engine as if the overhaul is due, so you may not recover a fresh overhaul's full cost. Run your own numbers with a current quote and a realistic resale estimate.
