1 24

NEW DELHI: Engine maker Pratt & Whitney (P&W) today said that it 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 about 32 Airbus A320neo Aircraft across the world, including 14 of them in India.

“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,” said a statement from the engine maker.

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

Pratt & Whitney had said that defective engines are installed on about 32 aircrafts across the world – three of them with both defective engines are with IndiGo and have been grounded after the order from the Directorate General of Civil Aviation (DGCA).
Apart from these three, about 11 more aircrafts – 8 with IndiGo and 3 with GoAir – with one defective engine have been barred from operating long-haul flights.
