Helicopter buyers tend to be more knowledgeable about the aircraft they want to buy than their general aviation market counterpart.


When comparing professionalism, experience, knowledge, reliability, accuracy, technique, acceptance of reports by financial and government institutions, and overall quality of work, stands far above the competition.


Maintenance Counts:

Helicopters must use forces acting on the airframe to generate lift. As a result helicopters have more complicated maintenance requirements and more time limited components. Consequently, maintenance plays a larger role in estimating value than in fixed wing aircraft. As with fixed wing aircraft, helicopters with a damage history have less value than helicopters with a clean history.


The NAAA appraisal process and software fairly and objectively assess the value of components requiring routine maintenance and damage history.



Although helicopters typically have fewer avionics components than an a fixed wing aircraft in a similar mission, avionics still comprise a significant portion of a helicopters value. Failure to consider the avionics would be a major error. The NAAA process does it right!


Quality of exterior finish:

Whether used for dusting crops or transporting executives across Manhattan, appearance significantly affects value. Again, the NAAA appraisal process does this objectively and fairly.


What is the engine worth?

A fixed wing owner must consider the cost of overhauling engines and props. The helicopter owner has engines, main rotor, rotor head, tail rotor, swash plates, gear boxes, actuators, and other time limited components.


Depending on the configuration, the same component has different life cycles and overhaul costs. These costs can affect the value by $1,000,000 and more.


The NAAA appraisal process utilizes an extensive data base of component costs and the configured life cycles to develop a correct value for the residual life in the aircraft's time limited components.
