AviationAviation

On 30 August 2025, a Turkish Airlines Airbus A330-200F freighter (TC-JOO) climbed without ATC clearance after the first officer misinterpreted an ATC message light, resulting in a loss of separation with a Flydubai Boeing 737 Max 9 (A6-FKR) carrying 173 passengers and crew. The two aircraft came within less than 1,000ft vertical separation along Route P574 in Mumbai's flight information region. India's AAIB has released its final investigation report, attributing the incident to absence of required cross-verification and misinterpretation of the message light. The A330F also suffered loss of separation with a Qatar Airways A320 and an Emirates 777-300ER during the same incident.

Initial Detection

On 30 August 2025, a Turkish Airlines Airbus A330-200F freighter (TC-JOO) climbed without ATC clearance after the first officer misinterpreted an ATC message light, resulting in a loss of separation with a Flydubai Boeing 737 Max 9 (A6-FKR) carrying 173 passengers and crew. The two aircraft came within less than 1,000ft vertical separation along Route P574 in Mumbai's flight information region. India's AAIB has released its final investigation report, attributing the incident to absence of required cross-verification and misinterpretation of the message light. The A330F also suffered loss of separation with a Qatar Airways A320 and an Emirates 777-300ER during the same incident.

The first officer noticed a blue ATC message light that illuminated, and assumed that clearance to climb was given. He initiated the climb, bringing the aircraft close to the Flydubai 737. The AAIB states the 737 was 3nm ahead and 2nm offset towards the right of the A330, prompting a traffic advisory signal on both aircraft.
