Ground time for aircraft powered by the new Pratt & Whitney PW1000G and CFM International Leap-1 engines has declined for the second month in a row, according to data from Aviation Week’s Tracked Aircraft Utilization tool.

The service tracks 4,500 airliners equipped with Leap-1 engines, which in January 2026 remained grounded for an average of 11% of the total time, or 3.5 days. Meanwhile, 2,600 PW1000G-powered jets spent 34% of their time idle in January.

Over the past two years, this average figure for Leap-powered aircraft has remained below 13%, while for aircraft with PW1000G engines, it stood at 36%.

According to Aviation Week’s Fleet Discovery data, 45% of the global Leap-powered fleet and just over 50% of the GTF-powered fleet are currently based in North America and Western Europe combined. It does not provide separate data for Central Asia.

However, CentralAsia+ Aero estimates that carriers in this region operate 36 Leap-powered aircraft and 39 jets equipped with Pratt & Whitney PW1000G engines.
