This study focuses on the expertise and experiential learning, especially learning in communities of practice, of flight procedure designers (specialists who design air routes for aircraft). Six experts were interviewed and an analysis using Modified Grounded Theory Approach was conducted. The results indicated that an informal secondary community, formed through activities in a formally established original community, plays an important role in learning for an individual. The secondary community and the original community play complementary roles, exchanging one's inherent information and knowledge with that of the other. Based on these findings, the theoretical and practical significance of such secondary communities was examined. Further consideration was made of environmental factors that would activate a secondary community.
