In support of the Federal Aviation Administration Technical Center's (FMTC) National Aging Aircraft Research Program (NAARP), Sandia National Laboratories and the John A. Volpe National Transportation Systems Center (Volpe Center) are conducting research to determine if current rules for design, inspection and maintenance are sufficient to ensure the safe operation of the aging fleet. Particular emphasis has been given to a phenomenon of multiple cracking that appears to be an attribute of airplanes that have been in service for some time. This phenomenon is commonly referred to as Widespread Fatigue Damage (WFD). Several experimental and analytical studies have been initiated by FAATC to understand the phenomenon of WFD. Some of these research activities include collection of strain gage data from a Boeing 737 airplane conducted by the Aging Aircraft Non-destructive inspection Validation Center (AANC), laboratory testing of full-scale curved panels conducted by Foster-Miller, Inc. (FM), and modeling of fuselage lap splices by the Volpe Center. This report documents the strain gage testing of the Boeing 737 airplane acquired by the AANC. Additionally, correlations among the three research activities mentioned above have been performed and are described in this report.
