**Ken Brock Manufacturing, Inc.** was an American [aircraft manufacturer](/source/Aircraft_manufacturer) founded by [Ken Brock](https://en.wikipedia.org/w/index.php?title=Ken_Brock&action=edit&redlink=1) in the 1960s and based in [Stanton, California](/source/Stanton%2C_California). The company specialized in the design and manufacture of [autogyros](/source/Autogyro) in the form of kits for [amateur construction](/source/Homebuilt_aircraft), including under the US [FAR 103 Ultralight Vehicles](/source/FAR_103_Ultralight_Vehicles) rules.[1][2][3]

Ken Brock Manufacturing produced a number of aircraft designs including the [Brock KB-1](https://en.wikipedia.org/w/index.php?title=Brock_KB-1&action=edit&redlink=1), [Brock KB-2](/source/Brock_KB-2) and [Brock KB-3](/source/Brock_KB-3) autogyros, plus the [Ken Hovey](https://en.wikipedia.org/w/index.php?title=Ken_Hovey&action=edit&redlink=1)-engineered [Brock Avion](/source/Brock_Avion) [ultralight aircraft](/source/Ultralight_aircraft). The company was also noted for the high-quality [aircraft parts](/source/Aircraft_part) that it produced for other designer's aircraft, especially the [Rutan Long-EZ](/source/Rutan_Long-EZ) and the [Cozy Mark IV](/source/Cozy_Mark_IV).[1][2][3][4]

The company occupied a 10,000 sq ft (930 m2) plant that included [lathes](/source/Lathe), [milling machines](/source/Milling_machine), [drill presses](/source/Drill_press), [tap and die](/source/Tap_and_die) making, equipment for [heat treating](/source/Heat_treating) metal, [plating](/source/Plating) and [welding](/source/Welding).[5]

A subsidiary was Santa Ana Metal Stamping, which Brock set up to produce [stamped metal](/source/Stamped_metal) parts using [numerical control](/source/Numerical_control) machinery.[6]

The company closed for business at the end of 2005 after Brock's death on 19 October 2001 while landing a [Thorp T-18](/source/Thorp_T-18).[7] After his death, Brock's widow, Marie Brock, who survived the 2001 accident, attempted to sell the business and parts on hand. [Aircraft Spruce & Specialty Co](/source/Aircraft_Spruce_%26_Specialty_Co) purchased the Cozy Mark IV parts inventory, jigs, tooling and drawings.[4]
