Gleaming new engines are a common sight on the display stands at NBAA, but it isn’t often showgoers get to see the complete components of a turboprop laid bare, let alone one being put together from scratch on the convention floor.

“This is first time at NBAA that to our knowledge anyone has done this,” says Chris Pratt, director of marketing for BBA Aviation subsidiary Dallas Airmotive, a turbine repair and overhaul specialist that has set up a mini-engine shop at the show. The Dallas-based company, which is celebrating its 50th anniversary as the first Pratt & Whitney Canada-designated overhaul facility for the ubiquitous PT6 turboprop, is putting together an 850-shp PT6A-42 here at the show in just three days.

“We want to show what our shops look like, showcase our capabilities and give people the chance to ask questions. Just as importantly, most pilots and a lot of mechanics have not seen a PT6 down to its component parts,” says Pratt. “People are fascinated by it – everyone from customers to competitors have come by and said this is pretty cool.
