IndiGo, GoAir to replace 180 unmodified PW engines by May 30: DGCA

Aviation regulator DGCA on Tuesday stated that IndiGo and GoAir will be replacing a total of 180 unmodified Pratt and Whitney (PW) engines on their A320neo planes with modified ones by the end of May this year.

IndiGo and GoAir have 106 and 43 such A320neo aircraft – fitted with PW engines – in their fleet, respectively. Post the induction of the aircraft into service, there have been a number of incidents of snag in their PW engines.

As there were more LPT (low pressure turbine) failure incidents in the aircraft in IndiGo’s fleet, the airline was directed by the DGCA on November 1 last year to replace all unmodified engines in its fleet with modified ones by January 31.
