Piper Aircraft and Hartzell Propeller are working together on approval for a five-blade composite propeller for the Piper Meridian and M500 through a supplemental type certificate (STC). Achievement of the STC for both Piper airplanes is anticipated by the end of fourth quarter this year.
The announcement was made at EAA AirVenture 2015 held in Oshkosh. “The Hartzell Propeller five-bladed prop was designed to enhance flight performance,” said Piper vice president of sales and marketing Drew McEwen. “This composite prop will help increase climb rate and decrease noise, with the added benefit of elevating ramp aesthetics. It is a win, win, win for our products,” he added.
“We are thrilled to work with Piper Aircraft on this next generation of enriched performance composite five-blade propellers for Piper’s top-of the line M-Class series,” said Hartzell Propeller executive vice president JJ Frigge. “The durability of the new Hartzell prop integrates exceptionally well with the Piper Meridian and M500 for all around better performance.”
Optimal in design due to its carbon fiber strength, the Hartzell five-blade composite propeller has been identified for use on current production Piper M500 products and will be offered as a factory installed option once certified. Piper Meridians already in the field can take advantage of this advancement through the STC.
The new Hartzell Propeller blades will be certified for unlimited life and are five to 10 times stronger than wood core blades. They feature a stainless steel shank, nickel cobalt leading edge, and mesh erosion screen for FOD protection. Hartzell’s latest Piper five-blade design is 15 pounds lighter than the current factory installed propeller and 10 pounds lighter than similar wood core propellers.
