  • In the TPE331 world, there are plenty of "experts" who know quite a bit about this series of power plant.  Without question, Turbine Standard represents the greatest gathering of knowledge, skill and ability with respect to the 331.  Whether it be parts acquisition or complete overhaul, their collective level of knowledge and expertise is without parallel.  We operate ten of these engines-they get the first call.  In addition, their customer service is "second to none".  If you want to play the "Aviation Game", call someone else.  If you want the work done properly, call Turbine-Standard - no excuses, just results?

  • We have been relying on Turbine Standard for engine overhaul and routine maintenance on our fleet of Conquests since 1998.  Their personnel in general, Mark Richardson and Dave Corwin in particular, are the most knowledgeable Garrett people I have found.  All work is done on time, on budget, and on your schedule.  Can't ask for more than that!

    Now that they are a Pratt overhaul/service facility, I look forward to bringing our King Air to Toledo for service.

  • When you need a company and its associates to "go the extra Knot" Turbine Standard is your PT6 Service Shop.  George Barber and his crack team of engine experts are some of the best I have had the privilege to work with.  They clearly understand flight schedules and the pressure of keeping Part 135 aircraft flying, keeping you in business.
