In considering the life cycle cost elements of a project, which relate to the costs of design, development, manufacture, operation and support of the aircraft, this study now focuses on the manufacture element of the life cycle cost with particular reference to the ‘in-house’ production manufacture cost.
This part of the life cycle cost, the in-house production cost, accrues all the costs related to turning the concept and design into an actual flying aircraft, capable of performing to its desired requirements.
This complex manufacturing process basically involves the stages of:- planning the manufacturing methods, converting raw materials into high precision airframe components, assembling the airframe, integrating the vendor manufactured components with the airframe, ground testing the compatibility and function of the systems throughout the complete aircraft, flight testing each aircraft to ensure compliance to full performance and safety and finally painting the aircraft in the required livery ready for despatch to the customer.
Having highlighted earlier the importance of the utmost reliability and ease of maintenance, it can be seen that it is essential for components to be designed and manufactured with this in mind, whilst ensuring the need for accuracy in productability, quality and affordability.
