Aircraft Spruce & Specialty Co. has acquired all existing inventory, tooling, and drawings for the prefabricated metal parts used in construction of the popular Cozy Mark IV aircraft. Ken Brock Manufacturing Co. of Stanton, CA produced the metal parts for the construction of the Cozy and Long-EZ aircraft since the mid-1970's until ceasing business operations on December 31, 2005. As the owner of the design rights for the Cozy Mark IV and the source for plans and kits, Aircraft Spruce wanted to insure that builders would continue to have a source for the former Brock parts, and now has the existing inventory in stock. There was no remaining inventory of some of the parts, but these parts will be available as soon as new production sources are established.
