East Hartford’s Pratt & Whitney said it has decided not to pursue the development of an aircraft engine with Rolls Royce.
Pratt and Rolls, which makes cars as well as plane engines, announced two years ago that they wanted to build a mid-size aircraft engine.
But after further discussion, the two companies decided to cancel the arrangement, citing the “regulatory environment.”
Pratt didn’t elaborate on that, but in a report this week, Reuters cited an unnamed source saying that the companies feared they would run into antitrust or competitive concerns from regulators because there are so few jet engine manufacturers.
Pratt said it remains fully committed to the mid-sized jet market segment and will continue to invest in engine developments independently.
