GE and the US Army shorten the T901 qualification plan by a year

The T901 received a Preliminary Flight Rating in June, clearing it for flight testing that counts toward formal qualification. GE has delivered seven flight-test engines and reports more than 2,900 hours of factory testing, plus Black Hawk flight tests in Florida.

Selected to replace the T700 in UH-60 Black Hawk and AH-64 Apache fleets, the engine is designed for 50% more power with improved specific fuel consumption. GE uses ceramic-matrix composites and additive manufacturing to reduce weight and part count.
