Faced with an FAA mandate to modify all of the Hawker 4000s delivered  thus far with fuel ­system upgrades that meet the latest certification  standards, Hawker Beechcraft is combining that work with an extensive  upgrade and enhancement program. The fuel system ­modifications require  removal of the interior and fuel system wiring harness isolation and other  changes, all of which bring the 4000 to amendment 102 standards of Part  25. The program, which will take about 90 days per airplane, includes  the fuel system mods and the Load 20 upgrade to the Honeywell Epic  ­avionics and Fadec software upgrade for the P&WC PW308A engines.  Hawker Beechcraft is paying for the program and alternative lift.
