<p>What do most pilots do wrong?  How often should you change the oil?  If you could only check ONE system during a preflight, what would you check?  Our fascinating guest, mechanic/pilot Ray Villalba of E&E Aviation answers all these questions and more on this week's episode of Behind The Prop!</p>

E020 - Part 61 vs. Part 141

Behind the Prop is the Podcast for anyone involved in aviation from general aviation to professional pilots.  Our hosts Bobby Doss is the owner of a flight school in Houston, Texas, and Wally Mulhearn is a pilot for a major airline and is also a designated pilot examiner (DPE) based in Houston, Texas.  Weekly they tell stories, share lessons and tips from behind the prop.  Together they have over 24,400 hours of flight time (Wally has over 24,000 of those) and collectively they provide very unique perspectives on general aviation, airplanes, and all things aviation.
