New engines made by Pratt & Whitney (UTX.N) for the latest Airbus (AIR.PA) single-aisle jetliner, the A320neo, pose a potential shutdown risk, the U.S. aviation regulator said on Wednesday.
The Federal Aviation Administration’s formal warning follows a similar action by European regulators on Feb. 9, and cites a “knife edge seal fracture” in the engine that could lead to an engine stall “and consequent inflight shutdown and rejected takeoffs,” the FAA said in an airworthiness directive.
The warnings mark the latest in a string of issues that have clouded the rollout of Pratt’s new engines, which compete with market-leader CFM International, a joint venture of General Electric Co (GE.N) and Safran SA (SAF.PA) of France.
A total of 98 engines could be affected, with 43 confirmed to have the problem and the rest possibly affected, Pratt said. The company declined to comment further.
