The crash was caused by poor weather conditions making the engines fail and failure to recontrol the aircraft.

During the descent the aircraft entered a region of severe precipitation, which caused both engines to flame-out due to very high levels of water ingestion.

The crew managed to re-light both engines but lost control and impacted the ground.

There were no failures of the aircraft or its systems reported before the crash, or discovered by the investigation team.

The first officer was 28-year-old Nicholas Gallmeister, who had joined the airline three months before the accident and had logged 4,063 flight hours, but only 143 of them were on the SA-226TC Metro.
