Pratt & Whitney has released a revised configuration as a solution to the issue relating to a knife edge seal on the High Pressure Compressor (HPC) aft hub which affected a limited subpopulation of the PW1100G-JM 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 & Whitney has begun implementing this solution and production engine deliveries incorporating this change will begin in early March.

The company will continue to work with Airbus and its mutual airline customers to minimize operational disruption.
