With DGCA ordering IndiGoNSE -2.59 % to replace all A320neo aircraft with unmodified Pratt and Whitney (PW) engines by January 31, the airline on Wednesday designated this matter as one of the “revenue headwinds” of 2019-20, and said it is “likely to have an impact on future capacity”. On November 1, aviation regulator Directorate General of Civil Aviation (DGCA) had asked IndiGo to replace all unmodified PW engines on its 97 A320neo family aircraft or face grounding of planes.
Later, unsatisfied with IndiGo’s speed in replacing the unmodified PW engines, the regulator on November 25 instructed it to ground an old A320neo family aircraft with an unmodified PW engine for every new A320neo plane added to its fleet to prevent large-scale cancellation of flights from January 31 onwards.
