This is a Cessna 337 owned by LAMP (Luthren Asssociation of Missionary Pilots). This bright red aircraft had been operated in Canada where the color would greatly enhance visibility in snow. It is at MMS for a dual engine overhaul and various airframe work. The unique arrangement of front and rear engines gives the power and reliability of a traditional twin engine aircraft without the assymetrical thrust experienced with an engine failure. In other words, if you lose an engine in a 337, the remaining engine won't try to pull you to the left or right.
Here is the rear engine mounted vertically by the crankshaft flange. This position allows access to every part of the engine for disassembly.

Notice the shrinking size of the engine as Paul Jones (left) and Scott Grote (right) remove components from the engine assembly until it is nothing but individual parts. Some of the subassemblies and critical parts are shipped out to specialized subcontractors for overhaul or inspections that look for defects beneath the surface.

This is Paul's first engine overhaul so he's getting great experience for his next engine, which will be the one on the front of this same airplane!
