MT-Propeller Service Station Newletter - TCCA Canada STC for Beech 300 series with 7-blade Silent 7 MT-Propeller

Atting, August 2026

MT-Propeller Entwicklung GmbH has received the TCCA Canada STC SA26-78 for the installation of the 7-bladed „Silent 7“ Propellers MTV-47-1- ( )-C-F-R(P)/CFR260-361( ) on the Textron Aviation Inc. Beech King Air 300, 300LW, B300, B300C powered by two Pratt & Whitney Canada PT6A-60A propeller turbines: for Models 300, 300LW, B300, B300C and PT6A-67A: optional for Models B300 und B300C.

This installation is also supplemental type cerfitied by FAA STC SA11914IB and the EASA STC 10085161.

MT-Propeller Vice President Martin Albrecht says that the installation features the following advantages:

- General performance improvement (8% take-off & climb, 4-5kts cruise)

- No propeller speed restrictions on ground while operating in low idle.

- Lower ITTs at high altitude.

- Unbeatable esthetic ramp appeal

- Significant cabin noise and vibration reduction

- All models comply with the strict German noise regulations 2010– „Landeplatz Lärmschutz Verordnung“for unrestricted airport operations in Germany and other European Countries.

Due to the smaller diameter, the 7-bladed MT-Propeller for the Beech King Air 300 Series has more ground clearance for less blade tip erosion and FODs.

The long-time proven MT-Propeller natural composite blades provide significant inside and outside noise reduction. They have no life limitation and are repairable in case of a FOD.

They also provide best vibration damping characteristics for almost vibration free propeller operation and have bonded on nickel alloy leading edges for superior erosion protection of the blades.
