Nestled in the hills of Southern Ohio is the Peebles Test Operation. This site consists of 10,000+ acres where numerous jet engine test stands and assembly buildings are located. Hatzel & Buehler has been performing the electrical maintenance here since 2001. In 2007 Hatzel & Buehler completed the Test Stand for the new Joint Strike Fighter jet engine. This Test Stand is the only one in the world built for our next generation jet fighter engine. Also, we have performed numerous projects related to GE’s new GENEX commercial jet engine.
