The Directorate General of Civil Aviation has raised three incidents of engine failure in IndiGo flights with engine maker Pratt & Whitney, aviation ministry said on Thursday.
The Directorate General of Civil Aviation (DGCA) has demanded that Pratt & Whitney identify the cause of engine damage and share data on engine failures globally, according to a statement by the ministry.
Pratt & Whitney and IndiGo, India's biggest airline by market share, did not immediately respond to Reuters requests for a comment.
Earlier this week, Pratt & Whitney parent RTX disclosed that a rare manufacturing flaw could ground hundreds of Airbus jets in coming years.
It is the second time the company flagged engine issues this year after it recalled 200 engines worldwide in July due to snags in the high pressure turbine parts and asked carriers to remove engines for inspection before Sept. 15.
Pratt & Whitney said earlier this week it was reviewing the need for a phase two recall for removal of up to 600 engines between 2023 and 2026, and will issue servicing plans in the next 60 days.
Eleven engines in IndiGo flights were "impacted" by the recall in July, civil aviation ministry's statement said.
IndiGo said on Tuesday it has been working closely with Pratt & Whitney to assess the potential impact of the engine failures.
