How reliable are aircraft engines?

The Federal Aviation Administration (FAA) was quoted as stating turbine engines have a failure rate of one per 375,000 flight hours, compared to of one every 3,200 flight hours for aircraft piston engines.

Are airplane engines more reliable?

Fact is, in many respects, aircraft engines are simply more reliable than automobile engines. While it’s true much of aviation’s basic technology is entrenched in the last century and auto engines are sometimes as modern as tomorrow, aircraft engines have some natural advantages.

What is the most reliable aircraft engine?

Meanwhile, at the point the type was grounded, 54 airlines were flying 389 737 Max jets, which had amassed 1.7 million flight hours. Petitcolin describes the Leap family as “the most reliable engine of its generation”.

How are aircraft engines so reliable?

The main reason jet engines are so reliable is that they have far fewer moving parts that rub against other things than any other type of engine. Sliding friction involving main crank bearings, connecting rod bearings, and at the cylinder wall/piston ring interface present is absent in jet engines.

How many years does a jet engine last?

Older and smaller jet engines typically have TBOs of 5,000 hours at the most. More modern engines have about 6,000 hours or more. With most business jets accumulating less than 500 hours of flying time a year, the schedule for modern jet engine MRO operations averages about 12 years or more.

Why do aircraft 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).

Why do aircraft engines cost so much?

Parts are outrageously expensive, in part because they’re relatively low production. Liability costs, labor, profit, all that adds up to an unfortunately ridiculous number. The shops that do the work are also relatively low volume, so they have to charge more per-job to make a reasonable profit.

What happens if a plane engine fails over the ocean?

If an engine fails after reaching V1 speed, the aircraft will continue its take-off roll and get safely airborne on one engine before returning to the airport. … The Boeing continued to fly for more than 3 hours on one engine over the Pacific Ocean, before landing in Kona, Hawaii.

What if engines fail on takeoff?

If an aircraft suffered engine failure on takeoff, the standard procedure for most aircraft would be to abort the takeoff. … If the engine failure occurs just after liftoff, the pilot must make a decision if there is enough runway to achieve an emergency runway landing, or if an off field landing is required.
