RTX said on Monday it would have to pull 600 to 700 of its Pratt & Whitney Geared Turbofan (GTF) engines from Airbus A320neo jets for quality inspections over the next three years.
The engine issue was first disclosed in July, but RTX made the extent of the problem clearer on Monday.
The announcement caused waves up and down the industry, from component manufacturers like Japan's Kawasaki Heavy Industries to airline carriers like Germany's Lufthansa that rely on the popular Airbus jets.
In July, RTX said microscopic contaminants were found in a powdered metal used in high-pressure turbine discs that are part of the GTF engine's core.
RTX is one of two manufacturers of engines for the popular narrowbody Airbus A320neo, the other being CFM International, a joint venture between GE (GE.N) and Safran (SAF.PA).
