The interim findings, based on cockpit voice recordings, flight data and wreckage analysis, showed the flight crew mistakenly switched off the less-damaged left engine rather than the right engine that had suffered the bird strike.

The investigation into a Jeju Air crash in South Korea has found both engines on the plane sustained bird strikes but the pilots turned off a less-damaged one just before its crash-landing.

Investigators have found that the pilots of the Jeju Air Boeing 737 that crashed in December, killing 179 people on board, seemed to have shut off the wrong engine that was damaged in a bird strike, according to reports.
