The scope of this inspection is designed to qualify an aircraft as a candidate for a formal pre-purchase inspection. The cost in money and time to perform a formal pre-purchase inspection is high; therefore, it is prudent to conduct preliminary inspections to qualify the aircraft prior to incurring the greater expense. The inspection process typically takes anywhere from one to three days, exclusive of travel time. This inspection involves a very thorough physical investigation of the known problem areas of the particular aircraft model. A thorough review of the aircraft records is conducted with an eye toward detecting damage history and identifying questions or anomalies associated with the aircraft records.
