Earlier, an Ahmedabad-bound Indigo Airlines flight suffered a tyre burst while taking off from Mumbai airport here on September 19.
However, all the 185 passengers on 6E 361, an A320 flight, were reported to be safe.
The similar incidents of technical snag had taken place in Indian airlines in past few months.
On September 2, a Pune-bound Airbus A320 neo plane of GoAir from Bengaluru had to return back after it suffered a technical snag.
GoAir spokesperson, following the incident, said that the flight "suffered a technical glitch".
Budged airlines IndiGo and GoAir have been grappling with P&W engine problem for several months now.
Last month aviation watchdog DGCA had in a statement said that seven IndiGo and two GoAir flights have been grounded due to Prett and Whitney (P&W) engine issues.
The latest incident comes barely a week after Civil Aviation Minister Suresh Prabhu had sought a report from the Directorate General of Civil Aviation (DGCA) on the grounding of the A320 neo planes.
There are 60 A320 neos with P&W engines operating in Indian skies as of now. Of them, 41 are with IndiGo and 19 with GoAir.
