Pratt and Whitney working with Airbus on glitches

The company said the latest issue is isolated to a limited sub-population of engines and more than 90 per cent of aircraft powered by the PW1100G-JM engines remain in service. Budget carrier IndiGo had said deliveries of Pratt& Whitney engine-powered A320 Neo (new engine option) aircraft

have been put on hold by Airbus and the engine maker. IndiGo, however, said it would continue to add A320 CEOs (current engine options) and ATR aircraft to its fleet. “Pratt & Whitney, with the support of Airbus, is in close contact with customers to address an issue that is isolated to a limited sub population of engines. “In India, more than 90 per cent of aircraft powered PW1100G-JM engines remain in service. We are working with Airbus and our customers to minimise any operational disruption,” the engine maker said. The company did not share the number of engines it has supplied to IndiGo and GoAir, who operate A320Neos with P&W engines. 

Both these airlines have placed orders for a substantial number of such planes.  Following the engine problem warning, IndiGo has already grounded three of its A320 Neos that are powered by P&W engines.
