SOLD - 1978 Beech Bonanza F33A - SOLD

N2023L is a two owner Bonanza F33A based in Indianapolis, Indiana area since new. The original owner was an attorney for a the Eli Lilly company, who sold it locally to an engineer in the auto racing industry in 2001.  There is no known damage history.

Equipped with GAMI-jectors and GAMI baffling, this plane runs extremely smooth lean of peak, and is very economical, cruising at 165-169 knots true airspeed on 12.0 to 12.5 GPH or so.  This engine has been run lean of peak since the break-in was complete, and has all better than 70/80 compressions on the original cylinders from the major, and very low oil burn.  The crankcase is a late phase III heavy case with the 7th stud. There is a record of every start that this engine has had since the major which will be included with the plane. It shows every quart of oil that has been added, as well as graphs of the oil analysis results.  There is a fresh oil analysis, just done within the last 10-15 hours of operation.

This is a ready to go plane that flew 125 hours in the 6 months before we took it in trade.  It is nicely set up for IFR operations, and will make for very reliable travel for the next owner. It is fully de-iced with TKS wing, tail, prop and windshield protection.

Larson Aircraft took this plane in trade for a Colemill President II Baron.

Please don't hesitate to call (303) 503-8356 with further questions regarding N2023L, insurance, finance options, upgrades or transition training. This plane is based at the Longmont Vance Brand Airport in the Denver area and can be viewed by appointment.

How we arrived at our price

In the current market, many of the conservative banks are using Vref for their standard for making aircraft loans, as they are seeing lower appraisal values based on Vref.  We are using Vref base values for establishing the price on this aircraft.  Most of these base values have gone down at least 35% (on piston singles) from the highs in the late 1990's and early 2000's. 

When appraising an aircraft, the base value is the starting point and applies to an "average" plane as specified by the appraisal tool. From there, the appraisal must be corrected up or down for engine time, total time, damage history, paint and interior condition,  significant modifications, and  avionics package installed.

Modifications and avionics that are in high demand can bring up to 85% of the current installation cost (for example a near new Garmin GNS-530 with WAAS), while more readily available and desirable modifications and avionics usually bring 35% - 50% of the new installed cost (a STOL kit or tip-tank kit).

We started with the Vref base price corrected per Vref for total time and engine time.  We then added and subtracted as appropriate for all the non-standard equipment.

This aircraft will present no problems for a standard 80% loan for a qualified buyer.  Often we can package avionics and other upgrades into the loan amount.
