ANAC Brazil STC for Airtractor AT-602, AT-802() with 5-blade MT-Propeller
MT-Propeller Entwicklung GmbH received the ANAC Brazil STCs 2026S04-04 and 2026S04-05 for the installation of the Quiet Fan Jet natural composite 5-blade propeller MTV-27-1-()-C-F-R(P)-J/CFR300-82( ) on the Airtractor AT-602 and AT-802() series powered by the Pratt & Whittney Propeller Turbines PT6A-45 (AT-602), PT6A-60 (AT-602), PT6A-65 (AT-602, AT802) or PT6A-67 Series (AT-802).
These installations are already certifed by EASA, FAA and TCCA Canada (AT-802).
MT-Propeller Vice President Martin Albrecht says that the installation features the following advantages:
About MT-Propeller:
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 and hovercraft. MT-Propellers can be developed for nearly every aircraft type from motor gliders to regional airliners.
Fulfilling the highest certification requirements, they are also supplemental type certified on Part 25 aircraft.
No active AD, this is a safety record no other manufacturer has achieved so far.
The MT-Propeller fleet is approaching a total of 125 000+ propeller blades on 34 500+ propeller systems in operation and can look back on accumulated 200 million flight hours in over 45 years.
With the best damage tolerance and repairability, MT-Propeller has the lowest operational cost of any certified composite propeller manufacturer.
MT-Propeller is holder of more than 230 STCs worldwide and OEM supplier for more than 90% of the European Aircraft Industry as well as 55% of the US Aircraft Industry.
With the longest industry TBO of 4500 hours or 6 years for the 5-bladed turbo prop MT-Propeller has proven reliability for years.
A factory certified network of 62 service centers provides best service and maintenance all over the world.
These installations are already certifed by EASA, FAA and TCCA Canada (AT-802).
MT-Propeller Vice President Martin Albrecht says that the installation features the following advantages:
- Best vibration damping characteristics for almost vibration free propeller operations.
- Bonded on wide chord nickel alloy leading edges for superior erosion protection of the blades.
- AT-802(): Take-Off improvement by 5%, so compared to the original AFM a higher safety for the calculated take-off run.
- No propeller ADs.
- TBO 4500 hours or 6 years, whatever comes first, for low maintenance costs.
- No intermediate inspections on a agriculture installation.
- No intermediate inspections are needed between the TBO which requires the propeller removal.
- Reduced cost for spare parts, like blades and lower overhaul costs, for the complete propeller assembly.
- No rpm restriction for the complete operational range.
- No life limitation and repairable in case of an FOD.
- AT-802(): ROC improved by 8% (Aerial Surveillance Configuration)
