FOR QUEEN AIR 2 writing tables and a pot-a-potty, complete engine cowling for the Queen, From the Queen Air (A-65),
Engine #1 has 507 hours on it but has been refurbished, pickled, and as you can see on shipping engine stands. It does have the logs.
Engine #2 has 1601 hours (TBO is 1400), but came off the Queen in working condition and has all logs also. Just need to be overhauled. Has a good case, crank, cam, and blower.
Queen, Twin Bonanza, Navion, older twin Commander.
The work on the good engine was done by Brant Aero in 04, they did 2 engines, and one was put on the queen to replace the high time engine.
There are only the Supercharger and gear box on the engines.
Also I have a complete engine cowling for the Queen, painted white in and out with no damage. It can be used on Port or Starboard.
