PC-12 with 5-blade MT-Propeller
We would like to thank MT for such a great product.

Mr. Finnoff
As you know, our PC12 is an early serial number with the 67B engine, not an NG, and we work it pretty hard, at an average yearly total of 500 + flying hours. Though we avoid unimproved strips, we land at many short paved airports all over the U.S. and Canada. These shorter strips sometimes require the use of a little reverse on landing. We have been operating with the MT now for 1 year . Over that year we saw significant performance improvements in thrust at takeoff and in climb performance over the old Hartzell as well as the reduction in noise and vibration levels.
With the recent installation of the newest MT blade redesign we have found even more improvement in a couple of areas. We have seen the abrasion pattern we saw on and aft of the old stainless leading edge, completely disappear, owing to the increase of the metal leading edge area and the harder nickel material.
The huge Anti Ice boot area and the new more flush design are helpful both in the anti ice performance and the aerodynamic aspect of performance.
We have now accumulated around 70 hours since the new, updated blade design was installed. During my last week with the aircraft I set up the same climb angle at 7 degrees nose up. The aircraft weight was averaging at between 7500 and 8500 lbs for this sample week. The OAT at takeoff was varying between 5 C to 10C at beginning of the climb to -35C at the top of climb. The climb performance was notable. The 7 degrees climb angle yielded 150 kts IAS at the initiation of the climb to 135 to 140 kt IAS at the top of the climb. Climb rate was 1500 fpm at beginning of climb through FL220 and rounding off at 1000 fpm from FL220 up to FL270. On colder days at low altitudes, I have seen the airspeed at 220 kts IAS regularly. Something I never saw with the Hartzell.
We would like to thank MT for such a great product. We would also like to thank you Chris for yours and Dave Noad's great support from the very beginning.
On those few occasions when we needed something, you and Dave were right there assisting us or the shops we contracted with for maintenance. I also received a couple of positive comments from the shops on the design and MT's product support.
We look forward to a continued good relationship with you and MT.
Best regards,
