To determine if potential continuing airworthiness problems exist for the small airplane fleet as a function of the aging process, the Federal Aviation Administration (FAA) established a research program to conduct a destructive evaluation of two aged airplanes (both Cessna 402 models) used in the commuter service. The intent of the program is to provide insight into the condition of a typical aged airplane and to see if a correlation exists between its maintenance history and current condition from a safety of flight perspective. This report provides a summary and comparison of the findings from the teardown examination of a 1969 Cessna 402A and a 1979 Cessna 402C model airplane in support of the research program. The results provide information for use in future investigations into the aged small airplane fleet and may determine if additional research is required to address specific problems observed (if any). The destructive evaluations of the commuter-class airplanes were separated into three main tasks: (1) inspection of the airframe and airplane systems, (2) teardown examination of the airframe and airplane systems, and (3) assessment of the airplane wiring.
