Turbine Aircraft Services provides product support services under contract to Mitsubishi Heavy Industries America, Aircraft Product Support Division, to Owners and Operators of MU-2 Aircraft. TAS acts as the source for communication between the owners and operators and MHIA for items such as operation of the aircraft, service difficulties, and can act as a conduit to MHIA engineering. TAS can assist with items such as publications and parts although these items are regularly handled through the MU-2 Authorized Service Center network. TAS staff brings a combined total of over 130 years of aviation experience, the majority of which is in support of the MU-2.

Turbine Aircraft Marketing, an arm of the TAS organization, provides access to some hard to find parts and many overhauled components, avionics, autopilots and instruments for the MU-2.
