FAA STC for Cessna T303 Crusader with the 4-blade MT-Propeller MTV-14

Atting, February 2017

Cessna T303 with MTV-14 MT-Propeller Entwicklung GmbH has received the FAA STC SA04049NY for the next generation 4-blade scimitar composite propeller MTV-14-D-C-F/CF(L)185-59b on the Cessna T303 Crusader powered by the TCM (L)TSIO-520-AE Engines.
The Installation is already supplemental type certified by EASA STC 10060646.

MT-Propeller President Gerd Muehlbauer says, that the installation features the following advantages:

  • Approximately 18 lbs less weight than the original propeller.
  • 10% shorter take-off distance over 50 ft obstacle (MTOW, SL, ISA conditions).
  • 2-3 kts faster depending on altitude or power setting.
  • Increased ground clearance for less blade tip erosion.
  • The STC complies with the strict German noise regulations 2010– „Landeplatz Lärmschutz Verordnung“for unrestricted airport operations in Germany and other European Countries.

The MT-Propeller natural composite blades provide significant inside and outside noise reduction. They have no life limitation and are repairable in case of an FOD.
They also provide best vibration damping characteristics for almost vibration free propeller operation and have bonded on stainless steel leading edges for best erosion protection of the blades.

MT-Propeller is the world leading natural composite propeller manufacturer with 30 certified propeller models from 2-blade to 7-blade hydraulically controlled variable pitch propeller, for engines producing up to 5000hp, and 2-blade to 4-blade electrically controlled variable pitch propeller, for engines producing up to 350hp as well as two blade fixed pitch propellers.

The high performance, light weight and durable MT-Propellers can be used on aircraft with piston engines and propeller turbines, as well as on airships, wind tunnels or hovercraft. MT-Propellers can be developed for nearly every aircraft type from motor gliders to regional airliners. Fulfilling the highest certifications requirements they are also supplemental type certified on Part 25 aircraft.

MT-Propeller is holder of over 210 STCs worldwide and OEM supplier for more than 90% of the European Aircraft Industry as well as 30% of the US Aircraft Industry. Over 20,000 propeller systems with more than 69,000 blades are in service.
130 Million fleet hours where already performed on MT-Propellers. 36 years ago, the first MT-Propeller was shipped.

A factory certified network of 62 service centers, provides best service and maintenance all over the world.

The FAA STC is in progress.

MT-Propeller President Gerd Muehlbauer says, that the installation features the following advantages:

  • General slightly enhanced performance
  • Approx. 44 lbs less weight than the original 3-blade propellers
  • Approx. same weight compared to theoriginal 2-blade propellers
  • No life limited parts
  • Reduced inside and outside noise for more flying comfort
  • Reduced vibration for less fatigue.
