This podcast led to an article in the October 2022 issue in which Scott Sellers writes about how to learn how to borescope yourself. Read that article here.

Scott Sellers has been a Cessna single-engine owner since 1995 (Cardinal, 182P, 182RG) and a pilot since 1975, all thanks to his wife Cindy, who tolerates, supports, and still enjoys flying after all these years. Besides this podcast, he is authoring a series in Cessna Owner magazine that involves Sellers updating and upgrading his new-to-him 1978 Cessna 182RG.
