Aviation minister Jayant Sinha said India's largest airline Indigo and competitor Go Air can use their grounded planes if they are able to secure "alternative engines" to be used in place of the faulty ones.
Under the Pratt plan, all defective components would be replaced by early June, requiring some planes to fly with one affected engine for nearly three more months.
The grounded planes, including the one that had a mid-air failure, all have Neo engines. Indigo's boroscopic tests (which are used to test defects or imperfections in aircraft engines and gas turbines) detected these anomalies in 69 instances, Business Today reported.
A senior DGCA official said 8 aircraft of IndiGo would be grounded. In an emailed statement to Bloomberg, the company said that it was working with its clients so that there is no disruption in operations and has already started delivering engines with the "upgraded configuration".More news: PM Oli says measures will be identified to reduce aircraft accidents
