Why a Structured Checklist Matters Before You Buy
Buying your first light aircraft is a significant financial and legal commitment. Unlike buying a car, there is no Carfax, no dealer warranty, and no standardized inspection process that happens automatically. The burden of due diligence falls entirely on you, the buyer. A structured checklist keeps you from skipping steps that could cost you tens of thousands of dollars after the sale closes. Work through each section below before you hand over a deposit.
Pre-Purchase Inspection: The Non-Negotiable First Step
A pre-purchase inspection (PPI) is an independent mechanical evaluation of the aircraft conducted by an Airframe and Powerplant (A&P) mechanic, ideally one who has no relationship with the seller. Budget between $500 and $2,000 depending on aircraft complexity. Do not skip this step to save money. The inspection will almost always surface issues that either lower the purchase price or save you from a bad deal entirely.
How to Choose an Inspector
Find a mechanic who is familiar with the specific make and model you are buying. A mechanic who works primarily on Pipers may miss known issues specific to a Cessna 172. Ask for references, confirm they hold an Inspection Authorization (IA) rating, and make sure they will provide a written report. Avoid using a shop recommended by the seller.
What the Inspection Should Cover
- Full airframe inspection for corrosion, cracks, and previous repair work
- Engine compression test and borescope inspection of each cylinder
- Review of all fluid levels, hoses, and fuel system components
- Landing gear, brakes, and tire condition
- Avionics function check and wiring condition
- Control surface travel and cable tension
- All placards, required documents, and emergency equipment present and current
Airframe Inspection Checklist
Even after a formal PPI, you should understand what the inspector is looking for. The airframe is the structure of the aircraft, and damage here can be difficult and expensive to repair correctly.
- Corrosion: Look closely around rivets, control hinges, and inside the wing roots. Surface corrosion can sometimes be cleaned, but exfoliation corrosion in structural members is a serious problem.
- Previous damage history: Ask the seller directly whether the aircraft has had any accidents or significant repairs. Then verify independently through the logbooks and maintenance records.
- Skin condition: Check for wrinkled skin near the firewall or tail, which can indicate a hard landing or prop strike that was never properly documented.
- Fabric aircraft: If you are buying a fabric-covered aircraft, have the fabric tested for strength. Faded paint is cosmetic; compromised fabric is a safety issue.
Engine Inspection and Hours
The engine is often the most expensive single component in a light aircraft. A new or overhauled engine can cost $20,000 to $40,000 or more. Pay close attention to the following:
- Time Since Major Overhaul (TSMOH): Every piston engine has a manufacturer-recommended Time Between Overhauls (TBO). An engine at or past TBO is not grounded, but you should factor the overhaul cost into your offer.
- Oil analysis history: Consistent oil analysis records show elevated metals before they become catastrophic failures. An engine with no oil analysis history is a minor red flag.
- Prop strike history: Any undocumented prop strike should require a mandatory crankshaft inspection. A prop strike that was not recorded is a significant liability issue.
- Compressions: A healthy cylinder typically reads above 72/80 on a differential compression test. Multiple low-reading cylinders indicate wear.
If you are looking at a single-engine piston aircraft, understanding the engine's status is especially important because there is no backup powerplant. Reviewing your options for single-engine aircraft insurance early in the process gives you a realistic picture of ongoing ownership costs.
Avionics Inspection
Modern avionics add significant value to a light aircraft, but aging avionics can be expensive to repair or replace. During the inspection, verify the following:
- All installed avionics are functioning correctly, not just powered on
- ADS-B Out compliance is confirmed (required in most controlled airspace in the U.S.)
- Transponder and altimeter/encoder have a current 24-month inspection (required for IFR flight)
- GPS databases are noted as expired or current, and you understand the subscription cost to keep them current
- Wiring behind the panel shows no evidence of amateur modifications or splices
Logbook and Records Review
The logbooks are the legal and historical record of the aircraft. Missing or altered logbooks reduce the aircraft's value and can create liability problems when you go to sell. Review the following:
Airframe Logbook
- Continuous maintenance entries with no unexplained gaps in time or hours
- All Airworthiness Directives (ADs) annotated as complied with
- Any Supplemental Type Certificates (STCs) documented with the appropriate paperwork
- Annual inspection entries signed by a licensed IA mechanic
Engine and Propeller Logbooks
- Total time and time since overhaul clearly tracked
- Any major repairs or component replacements documented with part numbers
- Propeller overhaul or replacement history, including any prop strike investigations
If the seller cannot produce complete logbooks, treat missing records as missing aircraft history. It is not automatically a deal-breaker, but it should significantly reduce what you are willing to pay, and you should disclose the gaps to your insurer when setting up your owned aircraft insurance.
Title Search and Liens
Aircraft titles in the U.S. are registered with the FAA Aircraft Registry in Oklahoma City. Before closing, you need to confirm two things: the seller actually owns the aircraft, and there are no outstanding liens against it.
- Order a title search through a reputable aviation title company. Fees typically run $100 to $300.
- Confirm the registration matches the aircraft's serial number exactly.
- Check for any UCC filings or financing statements that could follow the aircraft to the new owner.
- After purchase, file your own registration with the FAA promptly. The pink copy of the application must be in the aircraft until the registration certificate arrives.
If you are transitioning from renting to owning, you are used to relying on the flight school's paperwork. As an owner, that responsibility is yours. Pilots who are still in the renting phase should look at aircraft renters insurance in the meantime, but once you take title, you need your own policy.
Insurance Considerations Before You Close
Do not wait until after the sale to sort out insurance. You need coverage in place the moment you take ownership, or ideally as soon as you start flying the aircraft for a test flight as part of the purchase process.
Your hull value, pilot experience, and the type of operations you plan to fly all affect your premium. Getting an aviation insurance quote before closing lets you budget accurately and avoid surprises. Some lenders also require proof of insurance before releasing funds for an aircraft purchase loan.
Frequently Asked Questions
Do I need a pre-purchase inspection if the aircraft just had an annual?
Yes. An annual inspection confirms the aircraft meets airworthiness standards at that moment. A pre-purchase inspection is done for your benefit by an inspector working for you, not for the seller or the FAA. The two serve different purposes.
Can I get aviation insurance before I have my private pilot certificate?
You generally need at minimum a student pilot certificate and be working toward a rating to be listed as a pilot on an aircraft owner policy. Requirements vary by insurer. Contact a provider directly to discuss your specific situation before purchasing an aircraft.
What happens if the logbooks are missing?
Missing logbooks reduce the aircraft's value and may complicate insurance applications. You should disclose this to your insurer. The aircraft is still legally airworthy if it has a valid annual inspection, but you lose the ability to verify its full history, including past damage, overhauls, and AD compliance.
What does a title search actually check?
An aviation title search reviews FAA registry records to confirm the seller has clear title, checks for any recorded liens or security interests, and verifies the aircraft's registration history. It is a standard part of any aircraft purchase transaction.
How soon after purchase do I need to have insurance?
Immediately. The moment you take ownership or begin operating the aircraft, you are exposed to liability. Most buyers arrange coverage to begin on the closing date. Do not fly the aircraft without a policy in place, even for a short repositioning flight.
