N54DB is a 1970 production A60 Duke, rare in that it has been modified to B60 systems including the 232 gal fuel capacity upgrade, B60 / King Air pressurization system upgrade, and E1C4 engines that have been upgraded with carbide lifters.  My understanding is that there has yet to be a cam/lifter failure documented with carbide lifters installed.  Straight 60 and A60 Dukes were equipped with the "Dukes" pressurization system components which evidently were problematic.  This plane has been updated to the King Air pressurization components as were the B60 models.

This Duke has been maintained for decades by Bob Brungard / Brungard Aviation in Boulder Colorado.  Bob Brungard started with the local Beechcraft dealer before for starting his own specialty shop for Dukes and Beechcraft products.  The magnesium tail surfaces and flight controls are impeccable on this Duke with regard to corrosion, which I would attribute to the climate this Duke has lived in, being hangared, and having been maintained by the Duke specialist.  The maintenance history of this plane shows in the way it flies.  The engines are as close to "set it and forget it" as turbo-charged piston engines get.  The engines start easily, run exceptionally smoothly, and temperatures are easily managable in all phases of flight. Pressurization goes right up to just short of red-line just like it is supposed to. Turbo-systems works like it should, climbing well all the way to the mid 20's with very easily managed temperatures.

Equipped with radar, Garmin 530 WAAS and Garmin 430 WAAS, and Century IV autopilot, this is a turn-key ready to go cross country machine.  If any prospective buyer is looking to do a touch-screen upgrade we can do a competetivelt priced installation that can often be included in financing.  Owner has upgraded to a turbine Duke - the turbine STC does not apply to the A60 or this airframe would have been converted.
