A Qatar Airways Boeing 777-200LR had to cut its flight from Doha to Auckland short after a hole on its engine cowling appeared after take-off. In a report from Simple Flying, flight QR920 had to return back to Doha after dumping fuel. QR920 is actually the 2nd longest flight in the world, right after Singapore to Newark of Singapore Airlines.
It was reported that right after take-off, the captain noticed a technical fault and declared an emergency. In order to dump fuel, the flight circled over the sea due to it being above maximum landing weight. The aircraft was airborne for about an hour and fifteen minutes. According to a passenger, the whole was described to be 40cm by 40cm.
The aircraft involved had a registry number A7-BBC based on Flightradar24 tracker app. It was replaced by another Boeing 777 which continued with the flight which arrived around 5 hours and 45 minutes late.
All passengers and crew members are safe.
