RTX shares tumble on Pratt & Whitney jet engine problem: additive manufacturing flaw requires inspection


““Pratt & Whitney has determined that a rare condition in powder metal used to manufacture certain engine parts will require accelerated fleet inspection,” forcing an inspection of 1,200 out of more than 3,000 engines produced between 2015 to 2021, RTX said on Tuesday. The inspections will occur over the next nine to 12 months, but there was no impact on engines that are in production, the company said.”

“Microscopic contaminants in a Pratt & Whitney proprietary metal used in the engine’s high-pressure turbine discs were present, RTX management told Wall Street analysts on a post-earnings conference call. Pratt & Whitney made up 30% of RTX’s total 2022 sales.”
