The short answer
Owners must maintain maintenance records for the airframe, each engine, and the propeller, documenting inspections (annual/100-hour), maintenance and alterations, and Airworthiness Directive compliance. Complete, continuous records are legally required for airworthiness and strongly protect the aircraft's value and financeability.
What Records Are Required
Federal rules require owners to keep maintenance records covering the airframe, each engine, and the propeller. These document required inspections (annual and, where applicable, 100-hour), maintenance and repairs, alterations (with the appropriate approvals), and Airworthiness Directive compliance, including recurring-AD status. Some records are kept until the work is superseded; others (like total time and inspection status) are retained and transferred with the aircraft.
Why Records Protect Value
Beyond the legal requirement, complete and continuous logbooks are one of the most valuable assets an aircraft has. Buyers, insurers, and lenders all scrutinize records — gaps suggest deferred maintenance or undocumented damage and can reduce value, raise premiums, or slow financing. A well-documented airplane finances and resells better. Keep records organized and complete, and treat missing logbooks as a serious red flag when buying. See our pre-buy guide.
