I believe Paul McBride may have given some bad advice regarding not pulling the prop through on engines that are not being used regularly (“Ask Paul: Prepare your plane for winter,” Nov. 9 issue). Unless Teledyne Continental Motors changed its policy recently, it “requires” the prop be pulled through every seven days or the warranty is void. Lycoming may have a different policy.
Paul McBride replies: I called an old friend at TCM to check the company’s current view on this issue. He was kind enough to check through TCM’s publications and found a current SIL 99-1, issued in 1999, that states in bold letters “Do Not Turn Prop.” Perhaps Mr. Johnson is looking at outdated material.
