Safety information to determine cylinder condition and tips to remedy issues prior to removal.  Historically, the rule A&Ps were taught about cylinders was simple: If the compression reading was less than 60/80, the cylinder had to come off for repair or replacement, period. This works well for mechanics, who are always happiest when they have clear-cut guidance to follow. But it was bad news for aircraft owners, who have to shell out several thousand dollars each time a jug gets yanked, and occasionally suffer catastrophic engine failure when the cylinder installation isn't done precisely right. In recent years, we've developed far more effective methods of assessing cylinder condition, catching problems early, and remediating them without the need for costly and risky cylinder removal. In this webinar, Mike Busch discusses these modern methods, techniques, and practices.
