Budget carrier Indigo Airlines' Raipur-bound plane carrying 112 passengers returned to Hyderabad on Wednesday soon after take-off due to a "technical glitch", according to an announcement by the company.
An IndiGo statement in New Delhi said the incident is being investigated by its flight safety team and aviation regulator Directorate General of Civil Aviation (DGCA).
"IndiGo flight 6E 334 from Hyderabad to Raipur after take-off experienced a minor technical glitch/over limit EGT (Exhaust Gas Temperature) with its engine 1," it said.
After carrying out the standard operating procedures, the flight crew landed the A320-232 aircraft safely back at Hyderabad and passengers were flown in another aircraft, the statement added.
Meanwhile, IndiGo and GoAir cancelled 48 flights on Wednesday as almost a third of their A320 Neo aircraft fleet remained grounded for the third day following a safety directive by DGCA. Of these flights, 42 are of IndiGo and six belong to GoAir.
In a statement on Tuesday, the airline said: "IndiGo has cancelled certain flights due to the grounding of our aircraft further to the DGCA directions which has been issued in the interest of safety. While we understand that this may cause inconvenience to some of our passengers, given that we have multiple flights to the same destination, we are proactively re-accommodating all our affected passengers on other flights."
"GoAir has complied with the DGCA directive by grounding the late serial number PW GTF engines. This has resulted in the cancellation of some flights originating out of 8 centres. Flight schedules are being altered to accommodate those affected. Alternate arrangements are made or offered to minimise impact and inconvenience. In cases where appropriate, free cancellation and re-booking options have been made available," a GoAir spokesperson said
Citing safety concerns, the aviation industry regulator asked IndiGo and GoAir to ground a total of 11 A320neo aircraft fitted with Pratt & Whitney 1100 engines.
With this, all the A320neo aircraft with PW1100 engines beyond serial number 450 have been taken off operation in India.
