A Quick Engine Change (QEC) unit for a historic P-38 fighter undergoes a rebuild at WestPac Restorations — on the campus of the (not quite open to the public yet) National Museum of WWII Aviation in Colorado Springs, Colorado:

QECs were developed to speed aircraft maintenance — containing an engine and all its support equipment, a QEC allowed an engine swap to be performed with a relatively short grounding of an aircraft.

I made this image on a recent tour of WestPac Restorations and the National Museum of WWII Aviation. The Museum has been designed and is in the process of collecting funding to start construction (anybody have $12M they can spare?). Meanwhile, they have monthly tours during summer months — my daughter and I went on a special tour this past weekend as part of an AIAA-sponsored group.

Cool stuff!
