An aircraft lien is a legal claim or right against an aircraft by a creditor. Because aircraft are mobile assets that cross state and international borders, tracking these claims requires a specialized approach that differs significantly from real estate or automotive sales.

1. THE MOST COMMON TYPES OF LIENS

Before a sale, your aircraft brokerage team will conduct a thorough search for several types of encumbrances:

  • Bank/Financing Liens: The most common form, held by the lender who financed the initial purchase.

  • Mechanic’s Liens: Filed by maintenance facilities or repair shops for unpaid services or parts.

  • Hangar/Storage Liens: Claims from FBOs or airports for unpaid hangarage or parking fees.

  • Tax Liens: Filed by government entities for unpaid federal, state, or local taxes.

2. THE ROLE OF THE FAA REGISTRY

In the United States, the FAA Civil Aviation Registry in Oklahoma City is the central clearinghouse for liens. However, a simple search isn’t always enough. Some liens are “unrecorded,” and international aircraft may also be subject to the International Registry (Cape Town Convention). Professional aircraft brokerage involves searching both to ensure the title is truly “merchantable.”

3. WHY A “CLOUDED TITLE” IS DANGEROUS

A lien “clouds” the title, meaning the seller cannot legally transfer 100% ownership to the buyer until the debt is satisfied and a “Lien Release” is filed.

  • For Sellers: An old, forgotten lien from a maintenance shop five years ago can stall a closing at the eleventh hour, causing a buyer to walk away.

  • For Buyers: Inheriting an aircraft with an existing lien means you are technically responsible for the debt, and the creditor could legally repossess the aircraft.

4. THE SOLUTION: ESCROW AND TITLE INSURANCE

In a professional aircraft brokerage environment, an independent escrow agent acts as the neutral third party. They hold the purchase funds and only release them to the seller once they have confirmed that all existing liens have been paid off and the “Release of Lien” documents are ready for filing with the FAA.

PROTECTING YOUR INVESTMENT WITH EXPERT OVERSIGHT

The legal complexity of aircraft titles is exactly why “going it alone” is a high-risk strategy. Navigating the evolving global marketplace requires a sophisticated approach to aircraft brokerage, where careful planning and deep market knowledge are the keys to a successful sale, ensuring a satisfied client experience.
