The company closed for business at the end of 2005 after Brock's death on 19 October 2001 while landing a Thorp T-18.{{Cite web|title=NTSB Accident Number: LAX02FA008|url=https://www.accidents.app/summaries/accident/20011030X02171|access-date=2021-06-26|website=www.accidents.app}} 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 purchased the Cozy Mark IV parts inventory, jigs, tooling and drawings.
