the aircraft on takeoff and landing; Pivot 2 (the "forward" one) allows sharp turns when unlocked. In spite of having the tail wheel locked, the Beringer assembly allows taxi operation and steering; when sharp turns are required the tail wheel can be unlocked from the cockpit. www.Beringer-Aero.com A New Composite Kit-Built Helicopter Innovator Technologies, manufacturer of the Mosquito helicopter and Composite FX, have partnered to build a new two-place, side-by-side helicopter called the Swift that was on display in the Ultralight area. The Swift will have an empty weight of 900 pounds, a payload of 700 pounds, a 100-mph cruise speed, and a 120-mph maximum speed. Range of the 185-hp helicopter is 3.5 hours or 350 miles. The tail rotor is an enclosed Fenestron; the main rotor diameter is 26 feet. It will have a full-suspension rotor system, two composite rotor blades, an all-composite fuselage (74 inches wide), and 35-gallon fuel tanks. munity manager, during an AirVenture press conference. The award recognizes Rotax for its outstanding contributions to the advancement of light aircraft design. During AirVenture, Rotax revealed that real-life flight tests are showing a fuel economy improvement of up to 36 percent with the fuel-injected 912iS engine compared to the carbureted Rotax 912 ULS engine. The digital engine control unit (ECU) and the redundant electronic fuel-injection system ensure optimal fuel and air mixture at any altitude for a longer flight range, fewer CO2 emissions, and lower operating costs. The 912iS engine works with throttle settings below 97 percent in an "ECO Mode" with a Lambda 1.05 setting, which results in low fuel consumption. In a "Power Mode" above 97 percent throttle up to WOT, the Lambda is 0.88. The Rotax 912iS engine is currently available on 26 different aircraft types; 24 other OEM installations are in progress. BRP Rotax also announced it will offer new Rotax Extended Service Terms (REST) programs for owners of a 912 engine, starting October 1, 2013. Two warranty extension programs will exist. A "One Year Plus" program includes a one-year warranty extension or 200 additional flight hours, whichever comes first. A "Full TBO" program offers three years additional warranty or up to TBO (2,000 flight hours), or whichever comes first. This program will be offered to all customers who have a four-stroke Rotax engine that is already covered by a warranty. Further details about the REST program will be released on October 1, 2013, and it will be effective starting from that date. www.FlyRotax.com The engine is expected to be a Lycoming-based, fuel-injected IO-360. Test flying is expected to begin by the end of 2013. www.Composite-FX.com Andair Dual Fuel Pump EAA Homebuilding Community Manager Charlie Becker (right) presents the Raspet Award to Rotax's Christian Mundigler.

During AirVenture 2013, Andair introduced a new, duplex fuel pump for the Rotax four-stroke engine family. Two independently controlled fuel pumps are built into one aerospace aluminum body, called the PX375D-PR. It is self-priming, lightweight, and compact; it weighs just over one pound (18.2 ounces). The price is approximately $1,200. www.Andair.co.uk EAA Experimenter 27
