Flight test evaluation of the Prewitt Scratch Strain Gage (see Appendix for description) has previously been conducted on a T37-B jet trainer aircraft (Reference I). The results and findings of this program indicate that the gage is an effective damage monitoring device capable of measuring and recording strain cycles of a character and magnitude found in a fighter aircraft structure. In cooperation with the C-5 SF0, scratch gages were installed on a C- 5A Galaxy temporarily based at Wright-Patterson Air Force Base, in an effort to demonstrate the operation of the scratch strain gage on a transport aircraft. A secondary objective of the program was to collect in-flight strain data in the vicinity of the connection of the inner wing to the center wing, W.S. 120.
