Weatherly Aircraft Announces Exclusive Engine Option; Offers Fuel-Injection Option for Radial Engine Fuel Efficiency and Lower Cost of Operation.

MCCLELLAN, Calif. -- Weatherly Aircraft Company (OTC:WACF), the manufacturer of leading cost efficient, safe and reliable aerial application aircraft since 1961 for agricultural spraying and fire fighting applications, announced a new electronic fuel-injection option for its radial engine aircraft, significantly increasing fuel efficiency and lowering the total cost of operation over the life of the engine. The option is expected to be certified and available before the end of 2005.

The electronic fuel injection engine has been developed by Tulsa Aircraft Engines in conjunction with RSW Products. Tulsa Aircraft Engines (TAE), in Tulsa, Oklahoma, is Weatherly's long-time supplier of the Pratt & Whitney R-985 radial engine designed into the Weatherly 620-B aircraft model. RSW Products (RSW) is an R&D laboratory in Houston, Texas, headed by Robert Schweis, a leading design engineer who specializes in aircraft power technology "fire-wall forward."

Weatherly has been working with TAE and RSW on specifically applying the fuel injection upgrade to the Pratt & Whitney R-985 radial engine, which is the standard radial engine delivered in the Weatherly Aircraft 620-B. The electronic fuel-injection (EFI) option for the R-985 is designed to improve the radial engine performance by increasing the engine power, reducing fuel consumption and reducing maintenance costs. EFI reduces vibration, cylinder-head temperature and other adverse conditions that contribute to engine wear and breakdown -- lowering the frequency and cost of maintenance for both the engine and the aircraft. Weatherly has the exclusive right to offer the electronic fuel injection engine option upgrade for the R-985 through at least calendar 2006.

Tulsa Aircraft Engines President Sam Thompson said, "We selected the Weatherly 620-B as the first production radial-engine airplane to wear the electronic fuel injection system. Weatherly builds aircraft for ag operators whose operations run on narrow margins and are sensitive to operating efficiencies. As a result, the benefits of the EFI engine upgrade should be easily measurable and noticeable to the ag operator."

Gary Beck, President and CEO of Weatherly, said, "Based on design parameters and the relatively modest cost of the EFI system, the operating savings plus additional revenue from increasing the spray payload and reducing the spray time, should provide a pay-back in less than one season for most ag aircraft operators, and the investment should extend the life of the engine by 25%. After pay-back, the annual financial benefit should be about 3-5% over a comparable non-EFI radial engine. For ag aircraft operations, where margins are narrow, that amounts to appreciable benefits in performance and profits."

"Weatherly ag aircraft cost-effectively meet the spray requirements of ag operators serving grain farmers -- wheat, soy, barley, corn, beans and rice -- prevalent in world agriculture. The EFI engine option lowers overall costs and increases profitability for ag operators in developing, as well as in developed, agricultural economies around the world. The addition of EFI to the 620-B also increases the price-performance competitiveness of the Weatherly radial engine aircraft in applications where more expensive turbine-engine aircraft tend to dominate," continued Beck.

About Weatherly Aircraft Company

Weatherly Aircraft Company, with manufacturing located at McClellan Business Park near Sacramento, CA, designs, manufactures and sells leading cost efficient, safe and reliable aerial application aircraft for agricultural chemical spraying and fire fighting for domestic and foreign markets. The Company's aircraft models are based on its proprietary FAA-issued "Type Certificate" authorizing specific aircraft designs and production processes. The existing fleet of agricultural aerial application aircraft in North and South America is aging and the number of manufacturers has decreased, providing the opportunity for Weatherly's cost efficient, safe and reliable aircraft to meet replacement as well as new demand. The company was acquired in September 2000 by Gary Beck, Weatherly Aircraft's major shareholder, President and CEO, who reorganized the business to re-establish manufacturing for growth. Weatherly recently received approval to initiate trading in its stock under the symbol WACF. To find out more about Weatherly Aircraft, visit the Company's website at www.weatherlyaircraft.com.
