How reliable are Lycoming engines?

That’s over a dozen per year, in a country with fewer than 10,000 “sport and recreational” aircraft. While the poor reliability of Jabiru engines jumps out (with over 40% of the engine failures), the study still found 86 failures of Lycoming and Continental engines.

What is the most reliable aircraft engine?

He agrees that the IO-360-L2A is the closest to the definition of most reliable. There is one bright spot. Lycoming’s roller tappets-available on many Lycoming engines for new aircraft and for replacement engines in legacy airplanes-appear to be doing well.

Is Continental or Lycoming better?

Continentals normally have more valve trouble than Lycomings. Lycomings have better valves and guides. A Lycoming usually has its carb mounted to the oil sump, either the bottom or rear, and feeds the cylinders via tubes cast into the sump and connecting tubing from there to the intakes.

How often do Lycoming engines fail?

The ATSB’s 2014 investigation into failure rates in piston engine powerplants showed that the traditional Continental and Textron/Lycoming engines had a failure rate of about 13 failures per 100,000 flight hours, with Rotax coming in at a slightly higher 15 per 100,000 flight hours.

How often do piston engines fail?

The good news for many T&T readers is the FAA says turbine engines have a failure rate of one per 375,000 flight hours compared to one every 3,200 flight hours for piston engines.

Why do airplane engines burn oil?

Air-cooled aircraft engines burn oil, thanks to their necessarily loose piston, piston ring, and cylinder wall tolerances, so ash-forming detergent additives are an aviation no-no (and why you don’t run auto oil in airplane engines).

How long can an aircraft engine sit?

The label says preservation is intended for 60 days maximum. No desiccant plugs, ports not sealed well, etc. Just preservative oil. You can read manufacturer’s instructions for longer storage periods if you look for them.
