Pratt implementing geared turbofan engine fixes

UTC Aerospace Systems supplies a significant amount of hardware to the Airbus A320neo, including its PurePower geared turbofan engine.

East Hartford aeroparts manufacturer Pratt & Whitney Co. said Wednesday it is fixing problems with its PurePower geared turbofan (GTF) engine that will be in place by early March.

Pratt first said Feb. 12 that 43 problematic GTF engines were installed aboard 32 Airbus A320neo aircraft. On Wednesday, the company said all of them will be fixed in coming weeks. The problem relates to a knife edge seal on the high pressure compressor aft hub in the engine that powers the Airbus A320neo aircraft.

"The solution is based on a design with which the company has significant experience, and this solution has received all necessary regulatory approvals," Pratt said in a statement.

Asked to elaborate, Pratt spokesperson Jenny Dervin said, "We're not giving any technical details beyond the press statement at this time. We're communicating with Airbus and our airline customers directly."

In addition, 55 engines are sitting on Airbus' assembly line awaiting the fix.

"We're working with Airbus on the scheduling for that," Dervin said.

Fixes will be delivered to both airlines and Airbus, which is based in Toulouse, France, Dervin said. The company will continue to work with Airbus and its mutual airline customers to minimize operational disruption, she added.
