What happened
While conducting an oceanic ferry flight, the aircraft experienced a significant mechanical failure involving the right engine. Specifically, the engine developed issues with the magnetos, which severely limited the amount of power the engine could produce.
In an attempt to maintain flight, the pilot increased the power setting on the remaining left engine. However, this adjustment caused the left engine to begin overheating shortly after the power increase. Faced with the loss of one engine and the imminent overheating of the second, the pilot decided to perform an emergency ditching in the Pacific Ocean.
Findings
- The primary issue originated from magneto malfunctions in the right engine.
- The loss of power from the right engine forced an increased workload on the left engine.
- The overheating of the left engine necessitated the immediate descent and ditching procedure.
