Pilatus PC-12 Engine Failures: How Reliable is the PT6A Engine?

The Pilatus PC-12, powered by the Pratt & Whitney PT6A engine, is renowned for its reliability and efficiency. With over 400 million flight hours and a Time Between Overhaul (TBO) of up to 5,000 hours, the PT6A has one of the lowest in-flight shutdown rates—approximately 1 per 650,000 flight hours. While failures are rare, causes include foreign object damage, fuel contamination, and improper maintenance. The PC-12’s redundancy systems and emergency power capabilities enhance its safety, making it a trusted choice for single-engine operations.
