An IndiGo Airbus A320neo plane suffered a mid-air engine failure with a "loud bang" on Thursday and the civil aviation ministry has taken serious note of the incident, sources said.
The latest incident involving another Pratt & Whitney engine happened when the aircraft was flying to Kolkata from Chennai on January 3. The plane returned mid-way to Chennai and has been grounded there since then due to damaged engine blades, they said.
While sources said the engine of the aircraft stalled mid-air with a "loud bang", an IndiGo spokesperson said in a statement that its crew took note of a "technical caution"
