Specifically, the team calculated the equivalent stresses in the wing attachment structure for both aircraft and calculated safety factors to assess the two different designs. As part of this work, the team evaluated the efficacy of using a handheld 3D scanner to create a digital model of the components to be analyzed. The team also designed a camera stand that can be used to photographically document archival print documents. Finally, the team collected information on the aircraft restoration workflow at four museums to understand current practice, particularly with respect to use of software and 3D printing to create replicas of missing parts. The fact no digital model ofthe wing structural components exists posed a unique challenge as these had to be created to perform the structural analysis. A combination of archival print documents and measurements on the actual aircraft were used to create the 3D solid model. Key dimensions were checked throughout the process using measurements of accessible parts on the actual aircraft with the model adjusted accordingly. The solid model was imported into Ansys Mechanical where the stresses were evaluated under lift and drag loads representative of a typical flight condition for each aircraft. These results are summarized, and the team show that the CBY-3 wing attachment had a higher safety factor than that of the DC-3 . Finally, the team summarized the findings with respect to restoration workflow and concluded with some recommendations regarding software and resources for 3D printing.  \n“Certain materials are included under the fair use exemption of the U.S. Copyright Law and have been prepared according to the fair use guidelines and are restricted from further use. \"  \nAcknowledgements  \nThis MQP team would like to give thanks to the following individuals and/or organizations that have contributed to the success of this project:  \n􀁸 Dr. Adriana Hera and Dr. Erica S.
