MT-Propeller Entwicklung GmbH has received the FAA STC SA04526NY for the installation of the Quiet Fan Jet natural composite propeller MTV-27-1-( )-C-F-R(P)-J/CFR300-82( ) on the Airtractor AT-600, -800 Series Models: AT-802, AT-802A powered by a Pratt & Whitney PT6A-65 or PT6A-67 Propellerturbine.
The installation is already certified by EASA STC 10072601
MT-Propeller Vice President Martin Albrecht says, that the installation features the following advantages:
- 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
- ROC improved by 8% (Aerial Surveillance Configuration)
The MT-Propeller natural composite blades 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 nickel alloy leading edges for superior erosion protection of the blades.
