Why a Structured Checklist Matters Before You Buy
Buying your first light aircraft is a significant financial and legal commitment. Unlike a car purchase, there is no Carfax equivalent that tells you everything you need to know. Damage history can be buried in logbooks, engines can be close to overhaul without being disclosed upfront, and title issues can follow you long after the sale closes. A methodical pre-purchase process protects your money, your safety, and your ability to secure proper owned aircraft insurance once the aircraft is yours.
Work through each section below before you sign anything or wire any funds.
Start with the Logbooks
The logbooks are the aircraft's history in paper form. Review them before you spend a dollar on a physical inspection. If the logs are incomplete, inconsistent, or missing entirely, that is a red flag worth walking away from.
What to Look For in the Airframe Logbook
- Total time on the airframe
- All annual inspection sign-offs, with A&P and IA certificate numbers
- Any Airworthiness Directive (AD) compliance entries, including recurring ADs
- Records of major repairs or alterations, which should reference a completed FAA Form 337
- Any notation of damage history, even repairs that were later signed off
What to Look For in the Engine Logbook
- Time since new (TSN) and time since major overhaul (SMOH)
- Who performed the overhaul and whether it was done to new limits or service limits
- Any top overhauls, cylinder replacements, or prop strike entries
- Oil change intervals and any notes on oil consumption
- Whether the engine has been run regularly or sat for extended periods
A prop strike entry is particularly important. Even a ground strike requires an engine teardown inspection per most engine manufacturer guidance. If the logbook shows a prop strike with no teardown documented, assume the engine has unknown internal damage until proven otherwise.
Pre-Purchase Inspection: Hire an Independent A&P
Never use a mechanic recommended by the seller. Find an independent A&P mechanic, ideally one familiar with the specific make and model you are buying. A pre-purchase inspection is not an annual inspection, but a thorough one should cover most of the same ground.
Airframe Inspection Points
- Skin condition: look for wrinkles, ripples, or mismatched paint that can indicate prior structural repair
- Control surface condition and range of motion
- Landing gear, struts, and brake system wear
- Fuel system integrity and fuel cap seals
- Door seals, window condition, and any signs of water intrusion
- Corrosion, especially in the wing spar area and any areas prone to water pooling
Engine Inspection Points
- Compression test on all cylinders (80/80 is the standard target; anything below 60/80 warrants attention)
- Oil filter inspection for metal particles
- Borescope inspection of cylinders for scoring, rust, or carbon buildup
- Magneto timing and condition
- Exhaust system for cracks, which are a carbon monoxide risk
- Engine mount condition
Avionics Inspection Points
Avionics age quickly and repairs can be expensive. Have each piece of equipment tested for function, not just visual inspection.
- Verify the transponder and altimeter have current certifications (required every 24 months)
- Check the ELT battery expiration and last inspection date
- Test the comm and nav radios for clarity and accuracy
- If an autopilot is installed, test it in all modes
- Confirm any ADS-B Out equipment is compliant and working
- Note any avionics that are inoperative and factor repair costs into your offer
Title Search and Ownership Records
An FAA title search through the Oklahoma City Aircraft Registry will tell you who legally owns the aircraft and whether there are any recorded liens against it. Do not skip this step. Buying an aircraft with an outstanding lien means that debt can follow the aircraft, not just the previous owner.
- Search the FAA registry at registry.faa.gov using the N-number
- Confirm the seller's name matches the registered owner exactly
- Check for any recorded security agreements or liens
- If there are recorded liens, require a lien release before closing
- Consider hiring an aviation title company to handle the search and closing paperwork for a few hundred dollars. It is worth it.
After the sale, file the FAA Bill of Sale (AC Form 8050-2) and Aircraft Registration Application (AC Form 8050-1) promptly. You have 90 days to operate under a pink copy of the registration, but get the paperwork submitted right away.
Insurance: Get Quotes Before You Close
Many first-time buyers treat insurance as an afterthought. Do not. Getting aircraft insurance quotes before you finalize the purchase gives you a realistic picture of your true monthly cost of ownership, and some aircraft or pilot combinations may come with higher premiums than expected.
If you are buying a single-engine piston, make sure you understand the coverage options available. Single-engine aircraft insurance typically covers hull damage and liability, but policy limits, deductibles, and pilot warranty clauses vary significantly between carriers. Read the pilot warranty section carefully. If your logbook hours or ratings do not match what the policy requires, a claim can be denied.
Also factor in your flight hours and recent training. Insurers look at total time, time in type, and instrument currency. If you are transitioning from renting, note that aircraft renters insurance does not follow you into aircraft ownership. You will need a separate owner policy from day one.
Other Costs to Budget Before You Buy
The purchase price is just the starting point. Build these into your budget before you commit:
- Annual inspection cost (typically $800 to $2,500+ depending on aircraft and what is found)
- Hangar or tie-down rental
- Engine reserve (set aside a monthly amount based on TBO and overhaul cost)
- Avionics upgrades if needed for compliance or utility
- Insurance premiums
- Fuel burn at your expected hourly usage
Frequently Asked Questions
Do I need a pre-purchase inspection if the aircraft just had an annual?
Yes. An annual inspection confirms airworthiness at a point in time. A pre-purchase inspection is done independently on your behalf, and the mechanic's obligation is to you, not the seller. These are different things with different objectives.
How do I know if an engine is close to needing overhaul?
Check the time since major overhaul (SMOH) against the manufacturer's published TBO (time between overhaul). TBO is technically a recommendation for non-commercial operations, but proximity to TBO affects value and should affect your offer price. Also review compression numbers and oil analysis history if available.
What happens if the title search reveals a lien?
Do not close the purchase until the lien is formally released and that release is recorded with the FAA registry. Buying an aircraft with an unresolved lien can expose you to legal and financial complications even though you were not the one who created the debt.
Can I get aircraft insurance before the purchase is finalized?
Yes, and you should get quotes before closing so you know your true cost of ownership. Most insurers can bind coverage effective on the date of purchase once you have confirmed the sale details and provided your pilot certificate and logbook information.
What pilot qualifications affect my insurance premium?
Total logged hours, hours in type, instrument rating, and recency of flight experience all factor into your premium. Completing a manufacturer-specific transition course or a Wings program can sometimes reduce rates. Ask your insurer directly what training credits are available before you complete any courses.
