  7. Abstract:
  8. Lifetime extension would be a necessary preventive action to halt micro cracks expansion on the airplane external surface. To decide about whether to perform this operation, one should examine technological maturity, costs and technical parameters. Technical status in lifetime extension is one of the major drivers of this decision which should be considered in the first step of technology management process which is known as the technology attractiveness step. In this research, major technologies of rejuvenation is examined and categorized by the technology mapping. Also, key processes of rejuvenation and technological fields ranking has been determined by the procedural view tools of the technological attractiveness evaluations based on the selected technological fields. It should be noted that technologies are divided in to product based, process based and system based. Since considering all these technological fields is beyond the scope of this research, system based technologies are not considered. Current project provides a data base which could be beneficial for repair and maintenance technicians, senior managers of strategic lifetime extension and researchers of this field
