GROEN BROTHERS AVIATION’S AMERICAN AUTOGYRO SIGNS SPARROWHAWK DEALER IN PHILIPPINES

Salt Lake City, Utah – September 14, 2006 – Groen Brothers Aviation, Inc. (GBA) (OTC: BB GNBA) announced today that its American Autogyro division is further expanding its sales network by licensing a dealership in the Philippines.  The dealership, Gyroplane Rotorcraft, Inc., is owned and operated by Michael Cowan, a law enforcement specialist with experience in military relations and counter-terrorism.  This is American Autogyro’s seventh international dealership location.

Gyroplane Rotorcraft, Inc. will market the SparrowHawk II Gyroplane to the Philippine’s military, police agencies, delivery services and private citizens. “With the Philippine’s limited infrastructure, numerous islands and budgetary requirements, the SparrowHawk II is the ideal aircraft to fulfill the many needs of this country’s growing economy” said Mr. Cowan, “We are confident that orders will be forthcoming once we’ve demonstrated the maneuverability, ease of operation and economic aspects of the SparrowHawk for Law Enforcement, the Military and the private sector.”  Gyroplane Rotorcraft Inc. has placed an initial order for two SparrowHawk gyroplanes. 

“Establishing the Philippine market will greatly complement GBA’s efforts as they continue their expansion into the Pacific Rim and Asian Market” said Jason Chen, Groen Brothers Aviation’s V.P. of Business Development in Asia.  Within the Pacific Rim, American Autogyro of Sydney, Australia currently provides gyroplane flight training in their SparrowHawk and also offers a builder assist program.

Mr. Chen continues to introduce GBA and its autorotative flight technology to the Asian market.  He has met with Government, industry, and private individuals throughout the area.  In addition to attending many aviation trade shows in the U.S., GBA has exhibited at the Asian Aerospace Trade Show in Singapore, and in Beijing, China at Aviation Expo-China 2005 and China Police 2006.

“The two-place, enclosed SparrowHawk II Gyroplane is ideal for both public and private applications including: Border, Pipeline and Power Line Patrol, Airborne Surveillance, Search & Rescue, Sport Flying and Flight Training” said Al Waddill, Groen Brothers Aviation’s V.P. of Sales.

About Groen Brothers Aviation, Inc.

Developing gyroplane technology since 1986, GBA is recognized as the world’s leading authority on autorotative flight.  The company has developed the world’s first commercially viable modern gyroplane - the first “autogiro” to utilize a jet engine - the Hawk 4 Gyroplane powered by a Rolls-Royce gas turbine engine.  The Hawk 4 was used extensively for security aerial patrol missions during the 2002 Winter Olympics in Salt Lake City.  The gyroplane’s inherently simple design offers a safe and affordable alternative to helicopters and airplanes for many applications, including aerial observation roles in both government and private applications, agricultural aerial application, tour guide flights, and cargo/passenger transport.

Through its American Autogyro division, the company has also developed and is currently selling a smaller kit gyroplane, the two seat “SparrowHawk II,” and is offering this aircraft as a safe, extremely economical Airborne Patrol Vehicle (APV) for law enforcement and other government applications.   The Company is also developing a production two-seat gyroplane for both the “Airborne Law Enforcement” and the “Light Sport Aircraft” (LSA) markets.  The Company continues to develop a nationwide dealership network for the sale of these products.
