Adam A500 during flight test at the Mojave Spaceport
The Adam A500 is a six-seat civil utility aircraft that was produced by Adam Aircraft Industries. The aircraft is of pod-and-boom, push-pull configuration with its two Continental IO-550 piston engines mounted to provide centerline thrust. Adam Aircraft ceased operations on 11 February, 20081, and filed for Chapter 7 bankruptcy on 19 February, 20082, having delivered 7 A500s. In April 2008 Adam Aircraft was purchased from bankruptcy by AAI Acquisition Inc. This new company has indicated that they will pursue certification of the A700 jet as a priority and that the A500 will not be produced in the foreseeable future due to the continuing poor market for piston-engined aircraft.34
M-309The A500 was developed from the M-309 CarbonAero technology demonstrator designed by Burt Rutan and built by Scaled Composites at the Mojave Airport. The "309" designation refers to this being Rutan's 309th aircraft design. The 309 first flew in March 2000, but the aircraft has since been gutted and was used as a static display outside the Adam Aircraft Industries headquarters. 5 In 2006 the 309 was loaned to the Wings Over the Rockies Air and Space Museum and is now on display outside. Google Map DescriptionCompared to conventional twin-engine installations, the centerline thrust arrangement reduces drag and maximizes the controllability of the aircraft should one engine malfunction or fail. This engine configuration was used by the similar Cessna Skymaster. The A500 airframe is largely built of graphite composite materials. Other features include FADEC and cabin pressurization. The prototype A500 first flew on July 11, 2002 and was FAA certified in May 2005. A500 payload issuesIn evaluation flights conducted in 2007 the A500 was noted as being over the projected empty weight by 1,260 lb (571 kg) or 30%.6 The initial design empty weight publicized in 2003 was 4,200 lb (1905 kg), while the actual empty weight of the serial number 7 A500 was 5,460 lb (2476 kg). Initial gross weight was to be 6,300 lb (2857 kg), which has been increased to 7,000 lb (3175 kg). This resulted in a change of useful load from a forecast 2,100 lb (952 kg) to 1,540 lb (698 kg).6 With the 230 US gallon (871 liter) fuel tanks full, the available payload for crew, passengers and baggage is 160 lb (73 kg), down from a projected 720 lb (327 kg). This means that the A500 cannot carry full fuel and one standard weight adult male or female pilot.67 Adam Aircraft had intended to address the lack of useful load by demonstrating that the current 30 US gallons (114 liters) of unusable fuel is actually 10 US gallons (38 liters). This would have increased the useful load by 120 lb (54 kg) and allowed a full fuel crew weight of 280 lb (127 kg).6 Support & aircraft type club formationThe five A500s in private service have run into problems obtaining parts and at least one was reported as grounded due to parts issues in August 2008.8 The aircraft owners have organized an aircraft type club, the A500 Owners Association, with the goal of convincing the new owners of the design, AAI Acquisitions to provide parts support for the existing aircraft.8 AAI's head of customer support, Jan D'Angelo, responded saying:8
