Recent developments in the aviation industry highlight challenges with the reliability of next-generation single-aisle engines, notably impacting their economic and operational benefits. Engine manufacturers CFM International and Pratt & Whitney are actively working on hardware and software upgrades to extend engine life and reduce shop visits.
Engineers and industry leaders report that reliability levels in engines such as the CFM Leap-1A and Pratt & Whitney PW1100G have underperformed expectations, leading to increased maintenance costs and early removals. The reliability issues threaten to overshadow the fuel savings achieved through higher efficiency designs.
"Reliability levels for next generation engines and an increasing shop visit forecast indicate the problems of today are unlikely to moderate in the near term," stated Chris Celtruda, CEO of Chromalloy. Both OEMs are implementing improvement programs with a goal of achieving a more durable and reliable product over the next several years, aiming to mitigate the operational impacts and reduce AOG events.
In a recent statement at the Singapore Airshow, Pratt & Whitney’s president Rick Deurloo confirmed that the number of A320neo aircraft grounded due to GTF issues has been reduced by about 20%. He expressed confidence that, through continued enhancements, the industry will see more normalized engine performance by the end of the decade.
