Work on Cirrus aircraft

The McCauley STC and TC kit conversion catalog, published as a PDF on the company website, has a Cirrus single-engine piston section. It lists two kits for the Cirrus SR22 with the Continental IO-550-N engine: CIR443-01 with a satin spinner and CIR443-01P with a polished spinner. Both contain one D3A34C443 three-blade propeller with 78CYA-0 scimitar blades, oil filled, with a maximum diameter of 78 inches and a TBO of 2,400 hours or 72 calendar months. The catalog states that the kit contents are approved through the aircraft type certificate data sheet (A00009CH) and refers installers to the aircraft maintenance manual.
