An Air India flight from Delhi to Amritsar briefly entered Pakistan's airspace while manoeuvring during an approach to Amritsar airport on June 22, prompting an internal investigation and regulatory scrutiny.In a statement issued on Wednesday, Air India said the crew operating flight AI479 had "marginally infringed into the Pakistan airspace while manoeuvring a go-around at Amritsar airport"."The incident has been reported to the regulatory authorities and is being investigated internally," the airline said.The Directorate General of Civil Aviation (DGCA) said the Airbus A321 aircraft, registered as VT-PPV and operating flight AI479 from Delhi to Amritsar, was initially asked to hold during its approach due to a runway inspection following a bird strike incident.According to the aviation regulator, after the aircraft commenced its approach and was undergoing radar vectoring, it briefly entered Pakistan's airspace."The event was coordinated with Pakistan ATC Authorities," the DGCA said.The regulator added that the aircraft subsequently diverted back to Delhi and landed safely in the national capital.Neither Air India nor the DGCA reported any injuries or safety issues arising from the incident.
