After 40 years in the aviation parts business, one thing is clear; some aircraft models just keep flying. The Beechcraft King Air B200 is one of them. But keeping these workhorses airworthy requires a consistent supply of critical replacement parts.

Whether you’re planning ahead for scheduled maintenance or scrambling to solve an unexpected AOG event, knowing which parts fail most often, and how to source them quickly, can save you time, money, and flight hours.

Based on our real-world order history and MRO feedback from 2024, here's what King Air B200 operators are most likely to replace as we continue through 2025.
