Why Choosing the Right Maintenance Shop Is Essential for Every Pilot-Owner. Aircraft maintenance can either protect your investment—or drain your wallet and confidence. It depends on the shop you choose and how you work with them. Over the past two weeks, I spoke with two aircraft owners who shared similar frustrations. In both cases, the […]

Abnormal Combustion Events Will Eventually Kill Your Aircraft Piston Engine. Most aircraft piston engines still rely on technology from the 1960s and 70s. They lack modern sensors, knock detection, or advanced engine control units. This makes them vulnerable to detonation and pre-ignition—two forms of abnormal combustion that can destroy your engine if left unchecked. Modern

Understanding Aircraft Engine Cylinder Break-In. Breaking in new aircraft engine cylinders is a critical step to ensure longevity, efficiency, and optimal performance. Proper break-in helps seat the piston rings against the cylinder walls, reducing oil consumption and preventing premature wear. A poorly executed break-in can lead to glazing, high oil consumption, and reduced engine lifespan.

Why the Differential Pressure Test Alone Isn’t the Best Indicator of Engine Health. When evaluating the condition of your aircraft’s combustion chambers, the differential pressure test or cylinder compression test is often the go-to method. However, while this test has its place, it’s not without limitations. Misinterpretations of results or improper procedures can lead to
