Aircraft Bill of Sale: What Airlines and Buyers Must Know

In aviation, few documents carry as much weight as the Aircraft Bill of Sale. Whether you’re transferring a regional jet, a widebody airliner, or a business jet, this legal contract is the backbone of the transaction. It ensures that ownership is transferred cleanly, financial terms are clear, and both parties are protected from future disputes.

For airlines, leasing companies, and private operators alike, understanding the anatomy of an aircraft bill of sale is essential. Every clause, field, and signature serves a defined purpose — and overlooking even one detail can create costly legal complications.

Key Fields in an Aircraft Bill of Sale

1. Buyer and Seller Information
   The document begins by identifying both parties with full legal names, addresses, and contact details. This eliminates ambiguity, ensures accountability, and establishes a clear chain of ownership.
2. Description of the Aircraft
   Accuracy here is critical. The bill of sale must detail the aircraft’s make, model, serial number, year of manufacture, and registration number (tail number). These identifiers ensure there is no confusion over which aircraft is being transferred — especially vital in airline fleets with multiple similar aircraft.
3. Purchase Price
   The agreed-upon sale price is documented to validate the financial consideration, a core requirement for contract enforceability. For commercial aircraft, this figure may run into the tens or hundreds of millions of dollars, underscoring the importance of precise documentation.
4. Payment Terms
   Whether payment is made upfront, in staged installments, or via escrow, the bill of sale sets out clear expectations. For high-value airliners, escrow arrangements are common to protect both sides until all conditions are met.
5. Date of Sale
   This field establishes the exact moment ownership passes. It directly impacts liability, insurance coverage, and registration updates with the FAA or other aviation authorities.

Important Clauses in an Aircraft Bill of Sale

• Warranty and Representations
  Sellers typically confirm they hold clear title to the aircraft, free from liens or encumbrances. For buyers, this clause is essential protection against inheriting hidden financial or legal obligations.
• As-Is Clause
  A frequent feature in commercial transactions, this clause makes clear that the aircraft is sold in its present condition, with no further guarantees on performance. Buyers are expected to conduct thorough inspections and due diligence before closing.
• Indemnification
  Defines responsibility for liabilities incurred before or after the transfer. For instance, the seller may remain responsible for pre-sale maintenance obligations, while the buyer assumes all future costs.
• Signatures and Notarization
  Both parties must sign the document, and notarization often follows to verify identity and consent. This is typically required for registration changes with the FAA, EASA, or other authorities.
• Delivery Clause
  Specifies where and when the aircraft will be delivered, formally transferring possession and risk. For airlines, delivery location often aligns with maintenance bases or major hubs.
