Texas Turbine Conversions, Inc. modifies aircraft that use Garrett TPE331 engines, made by Honeywell. The company is based in Celina, Texas. The site says it has worked on these engines since the mid 1990s.

The site says the company has modified aircraft with these engines for over 20 years. It holds several supplemental type certificates for engine modifications on different aircraft models. The company says its staff includes engineers, mechanics, and pilots.

The company is known mostly for its work on the Cessna 208 and 208B Caravan. The site says the company has modified and delivered more than 150 aircraft around the world.
