Beechcraft Baron G58 Advanced Business Aircraft, United States of America
The Beechcraft Baron G58 is a twin-piston aircraft derived from Baron G55. The aircraft was first designed and manufactured in the name of Beechcraft Baron in 1969 by Beech Aircraft Corporation, which became a subsidiary of Raytheon Aircraft Company in 1980. The aircraft's maiden flight took place in June 1969 and it entered into service in 1970.
In 2004 Raytheon upgraded the aircraft with a fully integrated glass cockpit along with a Garmin G1000 avionics suite. The aircraft's name was changed to Beechcraft Baron G58 in April 2005, and it was certified in December 2005.
The Raytheon Aircraft Company was acquired by Hawker Beechcraft Corporation, US (HBC) in 2007. The aircraft is currently manufactured by HBC.
The upgraded Beechcraft Baron G58 made its public debut at the 36th annual Sun 'n' Fun Fly-in Expo held between 13th and 18th April 2009 in Lakeland, Florida, US.
On 21 June 2010, the Beechcraft Baron G58 was certified by the Civil Aviation Administration of China (CAAC).
In July 2010, the Beechcraft Baron G58 became the first aircraft of HBC to be approved for operations at the London City Airport.
Beechcraft Baron G58 aircraft variants
The Baron G58 has two variants known as the turbocharged Baron G58TC and the pressurised Baron G58P.
Both variants were introduced in 1976 and are powered by 240kW (325hp) Teledyne Continental TSIO520 engines. The panel system layout, which encompasses a throttle, gear, flap, propeller and mixture controls, was replaced with industry-standards features in 1984.
The limited and restricted head room for the pilot and co-pilot resulted in the termination of Baron G58TC / G58P aircraft's production in 1985.
Twin-piston aircraft orders and deliveries
As of 2007, around 38 G58 aircraft had been delivered to different customers worldwide. On 20 May 2008, the Artur Przygoda of Poland awarded a contract to the Hawker Beechcraft Corporation (HBC) to supply the European Aviation Safety Authority (EASA) certified Baron G58 piston aircraft. The delivery was made in May 2009.
Beechcraft Baron G58 features
The Baron G58 features an ice and rain protection system, which encompasses automated pneumatic de-icing boots, a standard electro-thermal propeller de-ice system, and standard heated stall warning vane and fuel vents. The aircraft also includes a stand-by alternator and secondary back-up battery for providing the required electricity to the engine when the primary battery's function fails. The multiple aircraft buses have increased the reliability and redundancy of the G58.
