April 11, 2011: Aerocast Inc. (CNSX: A; Frankfurt Stock Exchange: 0AE; www.aerocastinc.com) is pleased to announce that the company is now producing complex magnesium castings for Hamilton Sundstrand, which uses them to manufacture Integrated Drive Generators (IDGs). The castings (two different designs) form pressure control housings for IDGs that are used on the engines of Boeing 737 and Airbus A320/A330 aircraft.

Each aircraft has two engines, and each engine has an IDG to create electricity during the flight. Boeing and Airbus use these parts for new aircraft and as replacements for existing aircraft. The Boeing 737 and the Airbus A320/A330 are the most popular aircraft in aviation history. As of February 2011, over 6,600 Boeing 737s and over 4,500 A320s have been built.

About Boeing

Boeing is the world's largest aerospace company and leading manufacturer of commercial jetliners and defense, space and security systems. A top U.S. exporter, the company supports airlines and U.S. and allied government customers in more than 90 countries. Boeing’s long range forecast for 2010 anticipates delivery of 30,900 new airplanes over the next 20 years, valued at $3.6 trillion. To meet the demand for commercial aviation services, the number of airplanes in the worldwide fleet will grow at an annual rate of 3.2 percent, nearly doubling from around 19,000 airplanes today to over 36,000 airplanes in 2029.

According to Chief Financial Officer James Bell, Boeing will look at boosting 737 production to 42 or more a month after it reaches a planned increase to 38. The company has about seven years worth of backlog at current rates.

Airbus is a global enterprise of some 52,500 employees, with fully-owned subsidiaries in the United States, China, Japan and in the Middle East, spare parts centres in Hamburg, Frankfurt, Washington, Beijing and Singapore, training centres in Toulouse, Miami, Hamburg and Beijing and more than 150 field service offices around the world. Airbus’ latest Global Market Forecast provides an industry outlook for the 20-year period of 2010-2029, during which the company anticipates a 4.8 per cent annual increase in overall world passenger traffic.

With a commercial order book backlog of some 3,500 aircraft as of December 2010 – which is valued at over US$480 billion based on list prices – Airbus consistently captures approximately half of all airliner agreements signed in the commercial marketplace. Customers around the world have ordered more than 10,000 Airbus jetliners, with total deliveries surpassing the 6,500- aircraft milestone.

The Airbus Global Market Forecast for 2010-2029 foresees a prevailing long-term growth for the air transportation marketplace after a stronger-than-anticipated recovery, with the need for nearly 26,000 new passenger and freighter aircraft valued at US$3.2 trillion during the period to satisfy worldwide demand.

Airbus booked 644 gross commercial aircraft orders in 2010. The year’s new commercial orders included 452 A320 family aircraft.
