Disclaimer: We assume no liability for ultimate condition of this aircraft based on this “Pre-buy Evaluation”. This evaluation is not equivalent to an annual inspection which takes 24-32 hours on most Mooneys according to the Factory. This evaluation, usually 19 man hours, utilizing 7 hours of time for flight check and paper work inspection, and 6 hours of mechanical inspection, with 6 hours for the opening and closing of panels investigating common areas where problems can occur. Normally we are listing discrepancies requiring maintenance. This is not really an appraisal either, as we are not listing positive qualities of this aircraft. Damage history may not be noted or detected unless poor repairs are obvious. Usually our inspectors are not aware if the airplane is being represented as “no damage history”. Special attention to the history and other matters may be requested at the time of evaluation, but may not necessarily be included in the estimated 19 hours.


We are in business to keep you soaring. Whether you need professional service on your aircraft, or are looking for a hard to find part, be sure to contact us first, and contact us often!
