Can an Aircraft Purchase Agreement be e-signed?

Yes. Electronic signatures are legally enforceable under the ESIGN Act (15 U.S.C. ch. 96) and UETA where adopted, provided the signers demonstrate intent, consent, attribution, and retained records.

Is notarization required for the bill of sale?

Not universally. Notarization requirements vary by state and lender; some parties prefer notarized documents for additional authentication, while federal FAA registration primarily relies on properly executed instruments.

What if the aircraft has an outstanding lien?

Do not close until liens are cleared or subordinated. Require the seller to remove encumbrances or provide escrowed cure instructions to ensure buyer receives clear title.

How should I verify logbooks and maintenance?

Order a thorough inspection and records review during the inspection period. Consider a mechanic’s pre-purchase inspection and verify adherence to Airworthiness Directives and maintenance schedules.

Who files FAA registration forms?

Typically the buyer files FAA registration after closing with the executed bill of sale and any required documentation; parties can agree to have seller assist or use a designated agent.

When should I involve an attorney?

Consult counsel before signing if the transaction involves financing, cross-border issues, complex indemnities, or unusual title encumbrances to reduce legal risk and ensure enforceability.

What an Aircraft Purchase Agreement Covers

An Aircraft Purchase Agreement is a written contract that documents the sale and transfer of an aircraft between buyer and seller. It sets the purchase price, deposit and escrow terms, inspection period, representations and warranties about airworthiness and logbooks, allocation of taxes and fees, title and lien search requirements, closing deliverables (bill of sale, endorsement, registration forms), and post-closing obligations. The agreement coordinates federal registration and any lender requirements, and it provides the primary legal record used for FAA registration, financing, insurance, and tax reporting.

Why a Formal Purchase Agreement Matters

A written Aircraft Purchase Agreement reduces ambiguity by documenting price, inspections, title status, and who bears risk during closing. It protects both parties, clarifies financing and insurance responsibilities, and creates enforceable remedies if representations prove false.

Typical parties and intermediaries involved

Common users and stakeholders who prepare, review, or sign an Aircraft Purchase Agreement.

Buyer or buyer's counsel verifying purchase price, inspection windows, and registration responsibilities.
Seller or seller's representative confirming logbook entries, maintenance history, and clear title prior to closing.
Aircraft broker, escrow agent, or lender coordinating deposit handling, lien search, and funding for closing.

Representative signer roles and authority

Buyer Representative

An authorized officer, director, or individual with express authority to sign for the buyer; must be able to bind the purchaser and confirm financing commitments, insurance procurement, and acceptance terms in writing.

Seller Representative

A seller, broker, or corporate officer authorized to transfer title; should warrant that they hold good title, disclose encumbrances, and deliver any required endorsements, bills of sale, and maintenance logs at closing.

Core clauses every Aircraft Purchase Agreement should include

A professional agreement addresses price mechanics, condition and inspection rights, title and lien protections, closing procedures, and post-closing responsibilities in clear, enforceable language.

Purchase Price

Specify total price, payment mechanics, escrow instructions, and any holdbacks or price adjustments tied to inspection or discovery of defects.

Deposit and Escrow

Describe deposit amount, escrow agent details, conditions for release, and refund triggers if contingencies are not satisfied.

Inspections and Acceptance

Define inspection window, acceptable mechanics or facilities, corrective action thresholds, and buyer remedies for unsatisfactory findings.

Title and Liens

Require a certified lien search, seller representations of clear title, and procedures to clear encumbrances before or at closing.

Representations & Warranties

List seller and buyer promises about ownership, airworthiness, maintenance records, and authority; include survival periods for claims.

Closing Deliverables

Enumerate documents to be exchanged at closing: executed bill of sale, assignment, registration forms, release of liens, and proof of insurance.

Fraudulent Representations: Exposure to legal claims and damages

Contract Ambiguities: Costly disputes and litigation

Common mistakes to avoid when preparing the agreement

Using informal or ambiguous descriptions of the aircraft (omitting serial or N-number) that lead to record mismatches and transfer delays.
Failing to obtain a current lien search and clear encumbrances before closing, which can result in the buyer assuming unexpected debts.
Skipping a thorough logbook and maintenance review during the inspection period and later discovering unrecorded damage or deferred maintenance.
Neglecting to confirm signer authority for corporate sellers or buyers, increasing the risk of contested transfers and rescission claims.

Practical tips for accurate, efficient completion

Adopt consistent naming, attach supporting exhibits, and use escrow and inspection clauses to reduce disputes and ensure a smooth closing.

Use legal entity names

Enter corporate or individual names exactly as on formation documents or identification to avoid registration and title mismatches; include signer's capacity.

Attach maintenance records

Include logbook excerpts, inspection reports, and AD compliance as exhibits so buyers and lenders can confirm airworthiness and service history.

Specify escrow instructions

Provide detailed escrow agent name, account instructions, release conditions, and tie escrow actions to contract contingencies to prevent funds disputes.

Order lien searches early

Obtain FAA and UCC searches in advance and require seller remediation of encumbrances before closing to protect buyer and lender interests.

Example transaction scenarios

Two illustrative scenarios highlight common provisions and the operational steps buyers and sellers follow to complete a transfer.
