Significantly on Sunday, 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. We are working with Airbus and our customers to minimise any operational disruption,” the engine maker said in the statement. The company, however, did not share the number of engines it has supplied to IndiGo and GoAir—who operate A320Neos with P&W engines. Following the engine problem warning, IndiGo has already grounded three of its A320 Neos that are powered by P&W engines. “The product safety boards of P&W and Airbus, post- evaluating the PW1100G-JM engine issue, have decided that all Neo deliveries are on hold till further notice,” IndiGo said in a regulatory filing.
