Abstract : A survey was conducted to determine current in-service inspection practices for all types of aircraft structure and particularly for advanced composite structures. The survey consisted of written questionnaires to commercial airlines, visits to airlines, aircraft manufacturers, and government agencies, and a literature search. Details of the survey including visits, questions asked, a bibliography of reviewed literature and details of the results have been reported. From the results, a current in-service inspection baseline and a preliminary inspection program for advanced composite structures was documented as appendices to the report.
