The CE-335 Type Certificate Data Sheet (TCDS) is No. 3A25 available for view and down load on the FAA web site at
FAA - Home under T/C’s. It was certified in the (Normal Category), Approved October 2, 1979. This aircraft is Part 3 of the Civil Air Regulations effective May 15, 1956, as amended by 3-1 through 3-5. This is important because it is not a Part 23 aircraft.
It also came with 2 Teledyne Continental TSIO-520-EB engines. The engine in the rear tends to run HOT because of cooling issues and is a real pain to work on from the mechanic stand point of view.
The propellers are McCauley full-feathering 3-bladed propeller standard installations (a) McCauley hubs 3AF32C87 with 82NC-5.5 blades or McCauley hubs 3AF32C504 with 82NEA-5.5 blades. This you should really check very well because of pitting corrosion in the hubs that make them unusable and very expensive to replace.
The airframe has 11 AD’s 2 are reoccurring.
The engine has 21 AD’s 3 are reoccurring.
Over the years the aircraft has had landing gear issues (failures) and inadvertent gear up landing. Training is a must in this aircraft all the time.
For all the problems the aircraft has had I would suggest you may want to look at a Twin Comanche.
The maintenance costs on this model is very high sorry to say.
Just one man’s opinion.
