An IndiGo flight from Sharjah to Hyderabad was diverted to Karachi as a precaution on Sunday after the pilots observed a defect in one of the engines, officials of aviation regulator DGCA said.
On July 14, a Delhi-Vadodara flight operated by IndiGo had been diverted to Jaipur after vibrations were observed in its engines for a second. The DGCA is investigating both incidents, officials said.
In a statement about Sunday’s incident, IndiGo said that Flight 6E-1406 had been diverted to Karachi.
“The pilot observed a technical defect. Necessary procedures were followed and as a precaution, the aircraft was diverted to Karachi. An additional flight is being sent to Karachi to fly the passengers to Hyderabad,” the airline said.
The additional flight, sent from Ahmedabad, brought all the stranded passengers from Karachi to Hyderabad in the afternoon, sources said.
IndiGo’s competitor SpiceJet is currently under regulatory scanner. On July 6, the DGCA issued a showcause notice to SpiceJet following at least eight incidents of technical malfunctioning in its aircraft since June 19.
One of the incidents occurred on July 5 when a SpiceJet Delhi-Dubai flight was diverted to Karachi after the fuel indicator began malfunctioning.
The aviation regulator had on July 6 said that SpiceJet had “failed” to establish safe, efficient and reliable air services. It gave the airline three weeks to respond to the notice.
An official of the Pakistan civil aviation authority confirmed that an IndiGo flight had landed in Karachi.
“All the passengers have been taken care of properly and provided refreshments after they were moved to the transit lounge,” he said.
He added that engineering crew had detected faults in engine No. 2 of the IndiGo plane.
“The plane was not cleared for flight, so the Indian carrier has sent an alternative aircraft,” the official said.
Last year, a Lucknow-bound IndiGo flight from Sharjah had made an emergency landing in Karachi after a passenger fell ill midair. The passenger later died.
