EASA STC for 4-blade MTV-14 on Cirrus SR22T
MT-Propeller received the EASA STC 10089430 for the installation of the 4-blade MTV-14 propeller on the Cirrus SR22T powered by a Continental TSIO-550-K engine.

The FAA STC is in progress.

The installation of the 4-blade MTV-14 on the Cirrus SR22T provides an improved engine cooling, enhanced climb performance and shorter take-off distance.
The 3600 and 3400 lbs versions also comply with the strict German noise regulations 2010 – „Landeplatz Lärmschutz Verordnung“ – for unrestricted airport operations in Germany and other European countries.
