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.

OEM Partner: ConversionAir Kits

Who They Are
Steinbach & Associates’ ConversionAir Kits are engineered for efficient and accurate conversion of current R-12 aviation cooling systems to new industry R134a systems.

Why Their Product Matters
R12 Freon has gone out of production, hybrid blends of Freon have been rejected by OEMs and compressor manufacturers, and certifying exotic blends will likely also become an unfriendly FAA issue. As the owner or service provider of an R12 vapor cycle system, retrofitting the system to the new industry standard R134a refrigerant is the most practical solution.

The STC conversion kit features key components such as:

• Special R134a compatible hoses
• Compressor to minimize recurring maintenance
• Miscellaneous components and placards for smooth installation

The kits are available for King Air 90/100/200/300 series, Beechcraft 1900s as well as Bombardier Learjet 24/25/28/29/31/35/55/60 model aircraft.

Why We Distribute Their Kits
We’ve been serving King Air/Beechcraft 1900 operators, private owners and MROs for 35 years. We partner with companies who care about customers as much as we do. ConversionAir Kits fit the bill perfectly, and we’re proud to offer our customers this practical solution to the R12 situation.
