        ** LABOR ONLY  (Quoted price includes labor for the inspection but does not include parts, consumables, oil, filters and shop supplies.) 

  After the inspection is completed, a list of discrepancies, with estimated cost to repair each item, will be given to the owner/operator.   Next, a "decision-point meeting" will be had where written approval is given to the maintenance department to correct selected discrepancies. Only then, will repair work commence.  To clarify: All parts and labor for the correction of discrepancies, AD compliance and any additional items will be evaluated and quoted separately from the annual inspection.

​Keep in mind, the 24 month 91.411 and 91.413 Altimetry and Transponder certifications are not part of inspections. However, we will notify the customer when they are due.
