Welch Machine Inc. was the manufacturer of the landing gear for Commander Aircraft Company in Bethany Oklahoma from 1992 through 2000. Today we manufacture replacement parts as needed and supply the Commander owners with parts and assemblies from inventory. All parts are made from the original drawings, we comply with all material, heat treat and finish processing specifications as called out by the drawing just as we did during the production process.
