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 company said.
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.
