This is a Cessna 206 flown by MAF (Mission Aviation Fellowship).
This Piper Aztec (nicknamed the "AzTruck") is flown by Arctic Barnabas, an organization based in Alaska. The airplane was donated to Arctic Barnabas. Despite being well kept, MMS found 114 issues that need to be addressed. The aircraft will serve the Alaska community well because it is a heavy hauler and can fly in the rugged terrain.
Andy installed spark plugs for this engine. This plane flies in Africa. The organization used to trade out engines with Continental for $30,000/engine. Now they bring their engines to MMS (often over time in many pieces) to do an overhaul for $15,000. This gives the organization the ability to have 2 engines overhauled for the same price and ready for mission service.
Andy talked to many of the MMS mechanics throughout the day, learning from their perspectives and stories. One of the staff commented that each person brings unique skills and gifts to the hangar. Andy is eager to contribute to the ministry at MMS.
