Detailed Attention

Turbines Inc. is FAA approved to perform all work scopes from a PT6a Hot Section repair to full Overhaul on all PT6 models, and “yes” we are the experts on the PT6A-20. We perform all work in house to overhaul your engine not only saving you time but also money. All cleaning, NDT, Inspection, balancing, and testing is done right here at our Terre Haute facility. This translates into a high-quality product and a turn time that is second to none in the industry. We have refined our craft serving one of the most demanding markets in our industry. The use of the PT6 powered Agricultural Aircraft started our business and drove the turn time and reliability within our shop to meet the demands of that market. Our many corporate and private customers reap the benefits of that process with shorter turn times and lower maintenance costs.

The PT6a engine was designed to “WORK” and that is what it does coming out of our shop, with engines operating to 8000 hours plus with no significant repairs.

We also do conversions – Need a PT6a-28 to PT6a-34 conversion or other type? Let’s talk!

We understand that your hard earned dollar demands reliability, and downtime costs money. Every engine in our shop receives the highest level of attention and service to ensure quality and safety with a turn time that exceeds our customer’s expectations.
