Go to FAA.GOV. Look on the left side and see some tabs for pilots, mechanics etc. Click on pilots, then look at lower right side and see either a "MORE" choise tab or the TCDS Type certificate Data sheet tab. Then follow the instructions. it's A-759 BTW.
Type Cerficate Data sheet gives you all the information realtive to your aircraft. Associated engines, propellers, wheels, brakes, etc. If it is listed on the TCDS then you can add it to your aircraft with getting an STC or field approval.
