IndiGo To Upgrade Engine Software Of Full A320neo Fleet Written 20 December 2018

Reuters reports that IndiGo “said it will retrofit its entire Airbus A320neo fleet with a new software upgrade from engine-maker Pratt & Whitney after one of its planes was forced to make an emergency landing last week due to smoke in the cabin.” The carrier will retrofit the aircraft “within three weeks, IndiGo, owned by InterGlobe Aviation Ltd, said in a statement on Wednesday.” IndiGo and GoAir, which fly the A320neo in India, “have faced several issues due to problems with the Pratt & Whitney engines and were forced to ground the planes earlier this year.” The malfunction occurred in the engine’s “No.3 bearing seal, IndiGo said, with smoke from an oil leak in the engine entering the air system.” According to a statement by IndiGo, “Pratt is continuously developing fixes to improve the reliability of the No. 3 bearing seal.” The statement added that Pratt has introduced a software upgrade to alleviate the issue. Pratt & Whitney “declined to comment.”
