 The Cozy MK IV is a high-performance, four-seat canard aircraft which is comfortable, efficient, and economical to build. It has a range of about 1,000 miles and a top speed of 200 mph. When constructed according to plans and operated within the approval C.G. range, the canard configuration makes it highly resistant to stalls or loss of position control. The MK IV features full dual control and two-axis trim. The composite construction is very strong, resistant to corrosion and fatigue, and offers better protection to the occupants than other types of construction. |
Nat Puffer, the designer of the Cozy, is available to answer any questions regarding aircraft performance and construction for current builders or potential builders. Contact Nat by email at natshirlp@hotmail.com or by phone at (480) 981-6401. Builders are also encouraged to join builder groups and forums, as experienced builders can provide a wealth of valuable advice on construction of this wonderful aircraft. |

The Cozy Design is an Aircraft Spruce Copyright

Aircraft Spruce purchased the Cozy designs (Cozy III and Cozy Mark IV) from Co-Z Development, and as of January 1, 2004 has the exclusive right to market these designs.

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. |
Cozy Mark IV Custom Prefab Metal Parts |
These are the Cozy Mark IV Metal Parts manufactured by Ken Brock Mfg. Co. until January 2006, when Ken Brock Mfg. Co. closed their business and sold this parts line to Aircraft Spruce. Some of these parts are inventory obtained from Ken Brock Mfg. Co., and the rest are available from new sources. See the cozy home page at www.cozyaircraft.com for listing of current parts suppliers. |
