 The best place to get maintenance done is with Walter or Diemech Turbines but
if it is just routine oil/filter change and borescope ,there is a guy I know
 on the west coast that  could help you, contact me direct at mvr7@hotmail.com
so I can put you in contact. I do Walter engine installations , electrical
harnesses ,supply the TSLM and other electronic components for the Walter
engines and support those products.
