Previously, the DGCA had ordered grounding of 3 units of IndiGo's A320neo fleet after the European Aviation Safety Agency (EASA) had on February 9, 2018, issued emergency airworthiness directive regarding A320neo fleet the world over fitted with PW1100 engines (with serial number of 450 and beyond).
As per the directive, EASA has imposed restrictions "on grounding of aeroplanes having two affected engines within three flight cycles", the agency said in statement on Monday.
The agency also restricted the use of aeroplanes having at least one affected engine for "extended operations".
Clarifying its position, Pratt & Whitney in a statement said: "We are working closely with our customers to minimize disruption. The corrective action has been approved and we have already begun to deliver production engines with the upgraded configuration."
