If you have ever felt that knot in your stomach while a closing clock ticks, you are not alone. The fix is rarely complicated, it is about getting Form 8050 details precise, keeping documents consistent, and sending the right originals to the right place.
This guide walks you through AC Form 8050-2, the Aircraft Bill of Sale, how it fits with AC Form 8050-1, the fee, what to mail, where to mail it, and the easy-to-miss details that cause delays. I will flag practical tips we use in operations work so you can move from offer to ownership without drama.
Key Takeaways
- AC Form 8050-2 is the FAA’s official bill of sale that proves an ownership transfer for a used U.S. aircraft. It anchors the registration filing package.
- Expect to list exact buyer and seller legal names and addresses, the N-number, make, model, and manufacturer’s serial number, plus the purchase price and sale date.
- Signatures can be ink or acceptable digital, however the FAA’s acceptance rules are specific. If you email documents, they must meet the FAA’s digital signature policy. If you mail, send ink-signed originals.
- File the 8050-2 as evidence of ownership with AC Form 8050-1 and the current fee, which is $5, payable to the FAA. Include lien releases when applicable.
- Mail originals to the Aircraft Registration Branch or use FAA-approved electronic processes where allowed. Keep copies and use traceable delivery when timing matters.
FAA Aircraft Bill of Sale, AC Form 8050-2, What It Covers
Although it is a short form, AC Form 8050-2 is what creates the clean break from seller to buyer on paper. You will capture the buyer and seller legal names and addresses, the exact N-number, manufacturer, model, and serial number, plus the purchase price and sale date. That bill of sale becomes the core evidence of ownership for the FAA and insurers, and it ties directly to your registration application.
If a lien exists, plan for it up front. Include a signed release on lender letterhead or other acceptable evidence so the FAA can confirm clear title when it processes your registration. Submitting 8050-2 with the right lien documentation prevents avoidable back-and-forth and protects your timeline.
Where 8050-2 Sits In Your Filing
Think of your package as three parts working together:
- The bill of sale, AC 8050-2, proves ownership changed hands.
- The registration application, AC 8050-1, requests the certificate in the buyer’s name.
- The fee and any lien releases support issuance of the certificate. The FAA lists the registration fee as $5.
When the FAA approves your application, it issues AC Form 8050-3, the Certificate of Aircraft Registration. Since January 23, 2023, certificates are valid for seven years, not three, which reduced registry churn and delays.
Signatures, Originals, And Today’s Digital Rules
You have two practical signature paths:
- Ink signatures, then mail the originals with your package.
- Digital signatures that meet the FAA’s policy, then submit by the approved channels noted by the Registry.
The FAA has clarified it can accept documents with legible digital signatures and provides specific requirements, such as showing “digitally signed by,” the signer’s name and title near the signature, and an authentication mark. If your document carries only a generic electronic signature without those digital elements, it may be rejected. When in doubt, use ink originals for 8050-2 and mail them with the rest of the package.
Pro tip, if timing is tight, ask the Aircraft Registration Branch if your specific document can be emailed with a compliant digital signature. If a fee must be paid, expect to mail the fee and, often, the original documents together so the package can be matched and processed.
A Quick Word On Workflow Discipline
If you manage multiple closings, consistency wins. Use a standard checklist, name files in a predictable way, and pre-validate IDs, serials, and lien releases before anyone signs. That keeps you out of review loops and last-minute scrambles, and it mirrors how high-performing operations teams prevent rework.
What You Need Before You Start, IDs, Aircraft Data, Liens
Line up your identifiers and documents so the data on 8050-2 exactly matches what the FAA will see.
- Government issued photo IDs for buyer and seller, so names and addresses match what you will type on AC 8050-2.
- The aircraft’s N-number, manufacturer, model, and manufacturer’s serial number, verified against logbooks and the data plate.
- The purchase price and the date of sale.
- Lienholder details, lender name and address, and a signed lien release if the lien is being cleared.
- Contact fields, including a reliable mailing address for 8050-1. The FAA uses your mailing address and, if you list a P.O. box, it expects a physical address too.
Match ID to form, make sure buyer and seller names and addresses on the bill of sale mirror their IDs and what will appear on AC 8050-1. Small inconsistencies create big delays.
If you plan to use any digital signatures, confirm they meet FAA criteria before anyone signs. The Registry publishes what a legible digital signature must display, including authentication.
Step By Step, Completing AC Form 8050-2
Work through the Bill of Sale in this order:
- Confirm aircraft identifiers. Verify the N-number, manufacturer, model, and serial number.
- Enter buyer and seller legal names and mailing addresses, including titles where relevant.
- State consideration. Record the exact purchase price and the sale date, and note any non-cash elements.
- Sign and date. Each seller signs. Many sellers prepare two originals, one for the FAA filing and one for records.
- Address liens. Identify the lienholder or attach the release.
Mini Example, How Your 8050-2 Might Look
| Field on AC 8050-2 | Example Entry |
| N-number | N123AB |
| Manufacturer and Model | Cessna 182T |
| Manufacturer’s Serial Number | 18281234 |
| Purchaser Name and Address | Sky Valley LLC, 1000 Aviation Way, Phoenix, AZ 85001 |
| Seller Name and Address | John Q. Seller, 77 Hangar Rd, Tulsa, OK 74116 |
| Consideration | 345,000 |
| Date of Sale | January 27, 2026 |
| Lienholder or Release | First Air Bank, release attached dated Jan 26, 2026 |
If you are dealing with a company, trust, or trade name, include the human signer’s name and title next to the signature. The FAA expects typed or printed names next to signatures on registration documents.
Two Originals, Why Many Buyers Insist
Although one original is enough to submit, many transactions use two originals so the buyer can file one and keep one matched to the closing set. Some industry guidance even recommends the buyer receives both originals and the seller keeps a photocopy. This practice helps if you need to resubmit quickly.
Lien Releases That Actually Clear Title
A complete release identifies the aircraft, references the original security agreement or filing number, and is signed by an authorized officer of the lender. If you are using a UCC-3 termination, make sure the aircraft and parties are clearly tied to the original filing. Including the release with your package keeps the certificate from stalling at the Registry.
Where Accountably Helps, Light Touch
If you run a finance or tax team that supports client aircraft purchases, documentation discipline can make or break closing week. Our operational approach focuses on checklists, standardized workpapers, and name control so signatures, serials, and lien evidence line up. That reduces revision cycles and prevents last minute scrambles without adding headcount chaos.
File With The FAA, Forms, Fee, Addresses, And Timing
Your filing package usually includes:
| Item | Action |
| AC 8050-1, Aircraft Registration Application | Complete and sign, typed or printed name must appear with the signature |
| AC 8050-2, Bill of Sale | Submit original ink signed or an acceptable digital signature document per FAA rules |
| Lien release | Include lender’s signed release or other clear title evidence |
| Fee | Enclose $5 payable to the Federal Aviation Administration |
| Delivery | Send by traceable mail or approved channel and keep copies |
The FAA’s “Registering Your Aircraft” page confirms the $5 registration fee and emphasizes using the official AC 8050-1 application. Evidence of ownership includes one or more bills of sale.
Where To Send It
Use the correct address based on how you ship:
- U.S. Postal Service, regular or priority mail FAA Aircraft Registration Branch, P.O. Box 25504, Oklahoma City, OK 73125-0504.
- Commercial delivery services FAA Aircraft Registration Branch, Registry Building Room 118, 6425 South Denning, Oklahoma City, OK 73169-6937.
The FAA also describes when it will accept documents with digital signatures by email and explains that documents signed in ink must be sent by mail or commercial delivery. If a fee is due, expect to mail the fee with your documents so the Registry can match everything cleanly.
Temporary Authority And How Long Your Certificate Lasts
Once you file AC 8050-1, the “pink copy” or its equivalent temporary authority allows operation within the U.S. while the FAA processes the application, up to 12 months or until approval or denial. After approval, the FAA issues AC 8050-3, the Certificate of Aircraft Registration. Since January 23, 2023, that certificate is valid for seven years.
Translation, you get more breathing room now. Temporary authority can cover most normal processing delays, and the permanent certificate runs seven years before renewal, which smooths planning for owners and operators.
Common Timelines And Practical Tips
Processing times move with volume. The registry has worked to reduce a historic backlog, and the seven year rule helped by reducing churn. If you have a delivery or insurance cutoff, send a clean, traceable package, and avoid corrections that push you back in line. Keep a simple cover letter that lists what you are enclosing and how to contact you if something needs clarification.
Quick Checklist, Final Review Before You Mail
- Names and addresses match IDs and match AC 8050-1
- N-number, make, model, and serial number verified against the data plate
- Consideration and sale date filled in
- Each seller signed, name typed or printed adjacent to the signature
- Lien release attached if applicable
- Check payable to the Federal Aviation Administration for $5 included
- Copies made, tracking set, contact info in your cover letter
Light Accountably Note
If your internal team handles several closings a quarter, standard operating procedures and checklists save hours. We focus on file naming, review steps, and escalation rules so small issues, like a missing typed name next to a signature, do not become week-long delays. That is the difference between production chaos and reliable delivery in any compliance workflow.
Common 8050-2 Errors And How To Fix Them Fast
- Signatures that do not meet FAA expectations. Use ink or a compliant digital signature with authentication and the signer’s name printed next to it. If in doubt, re-execute in ink and resend.
- Serial number typos. Cross check against the aircraft data plate and logbooks before you sign. Correct with a clean, newly executed bill of sale if needed.
- N-number mistakes. Include the “N” and verify the exact digits. If a filing used the wrong number, contact the Registry and resubmit corrected originals.
- Lien surprises. Do not hide a lien. Attach a lender release or the right termination documents so the FAA can show clear title.
- Mismatched names and addresses across 8050-2 and 8050-1. Align them and resubmit with a short cover letter that explains the correction.
