A Customer's Simple Act Speaks Louder Than Words of Praise

Posted by Diane Heiserman on Tue, Nov 22, 2016 @ 08:00 AM

Earlier this year at our Lincoln, Nebraska, facility, we re-installed three Honeywell TFE731-60 engines fresh from their initial 3,000 hour MPI on their Falcon 900EX, that delivered on-time from its major C-inspection. The aircraft’s first scheduled flight back in rotation was a trip to Europe.

With decades of honed turbine engine skills, we experience very few surprises when it comes to Honeywell TFE731 engines and MPIs. However flying that far right after a major inspection is significant.

According to Jeff Schwebke, Duncan Aviation Engine Project Manager, most operators fly locally around their home base after MPIs are performed to make sure there are no minor squawks to work through. “This simple action by a long-time Duncan Aviation customer says more about their trust in our work than glowing words of praise,” he says.

With an average of 192 MPIs a year for the last 15 years, experience has told us which parts should be ordered in advance, what components need a closer look, and how to put together a team of trained turbine engine technicians ready to get to work for every customer.

With the triple MPIs completed, engines re-installed, and post-MPI performance runs, the customer’s aircraft departed with better engine performance than it had when it arrived.

Watch this time-lapse video and follow along as the engines make their way through the Duncan Aviation turbine engine shop for this triple MPI event.

35+ years

Duncan Aviation began servicing the first generation TFE731-2 engines in the early 1970s. In 1981, we received two major level authorizations to work on the Honeywell (then AiResearch) TPE331 and TFE731 engines. Over the years, as Honeywell added different TFE731 model engines, each was added to our capabilities.

Duncan Aviation's Honeywell Engine Authorizations, include: 

  • Heavy Authorization on TFE731-2,-3,-4,-5,-20,-40,-50,-60 engines
  • Minor Authorization on Honeywell AS907 (HTF 7000) Series 
  • Line Authorization on CFE738 Engines, GTCP36-100/150, RE100 series and RE220 series APUs.
