What is the most reliable piston aircraft engine?

Are piston aircraft engines reliable?

FAA analysis from the twenty years between ’84 and ’04 show that only 26% of accidents were mechanical and of those only 11% were reciprocating engine failures. In other words aviation piston engines are actually pretty reliable when used properly.

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.

What is the most common piston engine used on aircraft today?

As with the People’s Car, the vast majority of piston aircraft engines in service today use the Otto-cycle, invented by Nikolaus August Otto in 1876. Also called four stroke or four cycle, these engines contain a cylinder into which is fitted a piston; the piston acts on a crankshaft through a connecting rod.

What is the most reliable general aviation 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.

How often do piston 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 much is a new Lycoming engine?
