What happened
On January 25, 2018, a Boeing 737-530 operated by Peruvian Air Lines was performing a scheduled flight from Lima to Cuzco, Peru. After the aircraft reached a flight level of 37,000 feet, the No. 2 engine, a CFMI CFM56-3B1, underwent an uncommanded shutdown.
The flight crew declared an emergency and initiated a diversion back to Lima. During the descent, the crew attempted to restart the engine twice without success. The engine restarted following a third attempt. The aircraft, registered as OB-2140P, landed safely in Lima with both engines functioning normally.
There were no injuries among the 2 pilots, 3 flight attendants, and 94 passengers on board.
