The technological life of an aircraft is close to unlimited. As long as there are spare parts available an aircraft can be kept airworthy. The economic life of an aircraft, however, is not unlimited. Maintenance cost will increase when an aircraft becomes older and keep in mind that new aircraft with newer technology have higher passenger comfort and lower utilization cost, such as fuel and maintenance cost. When an aircraft has reached the end of its economic life, it will be withdrawn from service. Integral Support LTD was the company that assisted in dismantling of MSN316 with all airworhty spare parts included.
