Pratt & Whitney has ground-tested an upgraded version of the F100-229 fighter engine, the -229A, incorporating technology from US Department of Defense Integrated High Performance Turbine Engine Technology research. P&W say that performance expectations were exceeded in 110h of altitude testing. Temperatures and pressures are reduced at the present thrust rating of 130kN (29,000lb), extending hot-section inspection interval to 6,000h.

Shortages of cast metallic parts and other components continue hindering Pratt & Whitney’s (P&W) ability to produce new engines and to ramp up maintenance work needed to address its recall of PW1000G geared turbofans.
GE Aerospace’s deliveries of Leap turbofans slowed significantly in the second quarter of 2024 due to lingering supply chain troubles, with the company’s chief executive describing the quarter as “disappointing”.
Taiwanese carrier EVA Air has chosen GE Aerospace GEnx engines to power four incoming Boeing 787-10 widebodies.
