The Pre-Purchase Inspection (PPI) is an essential part of any used aircraft transaction.


    The PPI is an independent, professional, third-party service that assesses the condition of the aircraft before a purchase offer is made. A pre-purchase inspection performed by a neutral, type-qualified maintenance facility can help the buyer and seller make an informed decision regarding the true value and technical condition of the aircraft.


    As with buying a house, you want to know how the aircraft has been used and maintained, and if there are any structural or ongoing maintenance issues that could make the purchase too expensive. The pre-purchase inspection is a demanding process that benefits everyone involved.


    Primarily designed to ensure the airworthiness of an aircraft, the pre-purchase inspection generally has two aspects:

    • A thorough documentation review involves the analysis of all relevant information on the aircraft’s technical condition and history, including maintenance checks, findings and repairs.
    • Physical inspection of the aircraft, airframe, engine and avionics, to assess its condition and ensure proper operation.

    The pre-purchase inspection can identify possible anomalies that may not be obvious to the untrained eye, and thus save you significant expense later on or from using an aircraft that is not airworthy.


    That’s why customers appreciate our experience, expertise and flexibility.

    For helicopters, turboprops and light jets, the average turnaround time is 1 to 5 days. For medium and large jets, it will take 1 to 3 weeks. However, the aircraft’s ground time may last several months if the pre-purchase inspection is combined with scheduled maintenance or if there are airworthiness deficiencies requiring repairs.
