Building a Thorp T-18 Loading Spectrum

This presentation was originally given at the 2024 AFGROW User's Workshop in Layton, UT and was reproduced to be uploaded to You Tube. It shows the work required to return the airplane to airworthy condition, first flight take-off and landing, and the steps required to build a usage spectrum to estimate the crack growth life of the lower, outboard wing attachment lug. I would like to thank Alex Litvinov and Mark Thomsen for their support and encouragement as well as Jimmy Lambert for the excellent video editing.
