IndiGo Pratt engine replacement number shoots up

NEW DELHI: The number of snag-prone Pratt & Whitney (PW) engines that IndiGo needs to change in just over a month has risen from 120 to over 130 now, adding to the woes of the airline. The Directorate General of Civil Aviation (DGCA) will now next month decide on giving the airline to more time given the volume of engine replacement.
“Originally, the number of PW engines that required to be replaced on IndiGo Airbus A320 Neos was 120. After intense boroscopic and piston seal examination, the number now will be more than 130,” DGCA chief Arun Kumar said. Any IndiGo A320/321 Neo with an unmodified PW will not be allowed to fly from February 1, 2020, although the regulator may extend the date.
IndiGo recently said the regulatory requirement to have only modified – and hopefully less snag-prone – PW engines on all its Airbus A320/21 Neos by January 31, 2020, is “likely to have an impact on future capacity”.
