| ||In 1968 this Beech aerobatic Bonanza was converted in the factory from CE-244, a Beech E33A to a Beech E33C aerobatic model with new CJ-9 constructor number. In 1968 Beech did factory conversions of 13 E33As to E33Cs-these were CE-236 to CE-248 which became CJ-1 to CJ-13, respectively.|
In 1969 Beech did further factory conversions of 12 more E33A airplanes to E33C aerobatic airplanes. These were CE-251 to CE-255 which became CJ-14 to CJ-18, CE-257 to CE-259 which became CJ-19 to CJ-21, CE-261 to CE-263 which became CJ-22 to CJ-24 and CE-269 became CJ-25 for 12 total conversions in 1969.
So, 25 total conversions to aerobatic E33Cs occurred, and CJ-9 N160U should be a 1968 model instead of a 1960 model. Still, these are rare aircraft. A conversion of an aerobatic E33B was also offered to be converted from an E33 with just 225 Hp but no E33B was ever produced. The E33Cs with 285 Hp were priced at $38,250 faf.
Many structural changes were made to produce E33Cs, including Queen Air structural aileron ribs, Travel Air front and rear horizontal stabilizer spars, more aft fuselage stringers, heavier gauge skin on vertical stabilizer leading edge and larger rudder cables.
N160U being constructor number CJ-9 is a 1968 model E33C rather than 1960 vintage. The E33Cs were priced at $38,250 faf.
