STCs for Hundreds of Aircraft Models
We hold the rights to the Supplemental Type Certificates (STCs) for
the installation of MT Propellers on Aviat, Beech, Cessna, Maule,
Mooney, Piper, Experimental and more. From Cubs to Twin Turbines, we
can prop them all.
Now Available: 2 and 3-blade Composite props with full REVERSING thrust capability. The ultimate safety and
maneuverability feature for any float plane!
Product data sheets and performance test data can be found on the STCs Available page.
Reduced Weight
MT Natural Composite Propellers are significantly lighter than
aluminum propeller systems. This is a weight savings where it is
most important… On the end of your engine crankshaft.
Reduced Polar Moment
It takes power to swing mass. Less mass to swing with MT Props
means that power can be used to produce thrust.
Reduced Vibration
Aluminum supports harmonic vibration. Composite does not. (Have
you ever seen a wooden tuning fork?) Other parts of your plane
(gyros, motor mounts, radios, heat muffs, cowlings) will last
longer with reduced vibration. Because of this natural immunity
to harmonic vibration, most MT props do not require RPM range
limitation – set the power and RPM to your needs without worry
and trouble of “restricted range RPM zones” in standard
applications. Natural composite, by it’s nature, creates the
least amount of vibration as compared to metal or competing
structural composite propellers.
Greater Strength
Our durable Nickel-Cobalt leading edge is the strongest in the
industry, across any propeller on the market.
Life Unlimited
Metal props have absolute dimension limits. Every time you have a
nick filed out and the prop dressed, you get closer to that
limit. At some point it will exceed the use tolerances and must
be scrapped. In addition, each time a metal prop is dressed, you
will change the optimized performance dimensions established by
the manufacturer. MT Propellers, when overhauled, are brought
back to exact factory new dimensions.
Steel Hub Inserts
MT Propeller hubs use a hardened stainless steel bearing insert
that is replaceable. Standard hubs wear against the machined
aluminum and must be completely replaced when worn outside of
tolerance.
Quieter
Many of the MT STCs will utilize more blades, allowing for
smaller diameter blades. This results in lower tip speeds and
quitter operation
Fuel Savings
A good example of fuel savings can be found from our 182 test
platform ran 2300 rpm x 23” MP @ 130KTAS @ 12.5 GPH with the
standard 2-blade metal prop. With the MT Composite we ran 2100
rpm x 24” MP @ 130 KTAS at 11.5 GPH.
Many Service Centers
MT has a worldwide network of prop shops that have trained and
been approved to service MT Propellers.
Prop Strike
Lab tests and field experience has shown less damage with MT
Composite props.
Adds Resale Value
Many pilots consider an MT propeller a valuable upgrade and will
add value to the aircraft at the time of sale
Fully Warranted
1 year or 1,000 hours (which ever occurs first) for any
manufacturing defects.
