The Role of Due Diligence in Aircraft Purchase and Sale Agreements
Aircraft transactions can be complicated and involve significant financial risks. Whether you are buying or selling an aircraft, conducting thorough due diligence is critical.
Due diligence is the comprehensive appraisal of an asset's value and condition before a transaction takes place. From reviewing contractual terms to assessing regulatory compliance, thorough due diligence helps identify potential issues such as title defects, maintenance discrepancies, or regulatory violations that could impact the transaction.
When it comes to aircraft purchase and sale agreements, this process helps ensure that parties are well-informed and protected against unforeseen complications down the road. Whether you’re buying or selling an aircraft, understanding the importance of due diligence is crucial for avoiding costly mistakes and achieving a successful outcome.
At William G. Harger & Associates, PLLC, Attorney Bill Harger brings over 25 years of aviation law experience, paired with his unique background as a former pilot, to guide clients through these agreements.
Why Due Diligence Matters in Aircraft Transactions
An aircraft is a substantial investment, often involving millions of dollars. Without properly investigating the history, condition, and legal standing of the aircraft, buyers can unwittingly assume considerable liabilities upon purchase. On the seller's side, verifying clear documentation and compliance with regulations is necessary for an efficient and lawful transaction.
For instance, potential issues, such as unresolved liens, unclear ownership history, or undisclosed maintenance defects, can derail an otherwise promising deal. The role of due diligence is to identify and mitigate these challenges before they escalate, protecting all parties involved and paving the way for a smoother transaction process.
Attorney Bill Harger understands the details involved in these transactions. His legal background and hands-on knowledge of aviation allow him to give each client informed and practical guidance tailored to their unique circumstances.
Key Elements of Due Diligence in Aircraft Transactions
The due diligence process involves a careful review of legal, financial, and technical aspects to guarantee a successful and compliant transaction. Some elements involved in the process include the following:
Reviewing Aircraft Documentation
You should first conduct a detailed review of the aircraft's documentation. Buyers should verify key records, including the aircraft's title, registration, airworthiness certificate, and maintenance history. Any gaps or irregularities in these records could point to problems such as prior damage, improper repairs, or disputed ownership claims.
Attorney Bill Harger and his team assist clients with a meticulous review of all documents to ensure accuracy and completeness. Their involvement helps their clients know that essential details won't be overlooked.
Evaluating Legal Ownership and Liens
Before finalizing a transaction, buyers must confirm that the seller has clear ownership of the aircraft. Additionally, any existing liens or encumbrances associated with the aircraft must be addressed. This is particularly vital because failing to resolve these issues can result in significant future liabilities for the buyer.
At William G. Harger & Associates, PLLC, the legal team conducts detailed searches and works to resolve title or lien issues, making sure that clients can move forward without hidden complications.
Assessing Tax and Regulatory Compliance
Federal and state regulations, as well as tax implications, can significantly influence due diligence. The Federal Aviation Administration (FAA) and International Civil Aviation Organization (ICAO) maintain strict requirements regarding aircraft registration, operation, and compliance. States may have additional tax or fee requirements that buyers and sellers need to consider during the transaction.
Located in Richmond, Texas, William G. Harger & Associates, PLLC is well-equipped to address these regulatory and tax-related concerns for clients throughout the United States and internationally.
Inspection of the Aircraft's Condition
While the paperwork is critical, you should also address the physical state of the aircraft. A pre-purchase inspection can reveal significant details about the aircraft's structural integrity, engine performance, avionics, and more. This inspection also helps identify potential repair costs that could affect the final sale price.
Through decades of aviation experience, Attorney Bill Harger can guide clients on how to arrange for trusted inspections and use the findings during final contract negotiations. As a former pilot, he directly understands aircraft functionality and can help identify potential issues before the sale is concluded.
