Description:

On 22 August 2019, the AAII was notified by the domestic air operator of the Boeing 737-800 aircraft, identification OK-TVO, about a power unit failure during the TVS1125 flight, callsign TVS4MP, from LGSM to LKPR. Shortly after ascending to FL360, engine No. 1 shut down. The crew reported a technical issue to the ACC as a reason for descending from FL360 to FL240. They attempted to restart the shutdown engine twice. After the second unsuccessful start-up, the PIC decided to continue flying with only one operating power unit to the LKPR destination which he designated as a suitable airport. No sooner than upon entering the LKAA FIR, the crew declared PAN PAN, reported the defect nature, and landed at LKPR with 170 passengers on board. No passengers or crew members were injured.
