Hartzell Propeller Inc. announced that it has received an STC from the FAA for a Top Prop propeller conversion kit developed for the Piper Malibu(PA-46-31OP) aircraft. The availability of the kit gives owners the opportunity to upgrade their aircraft to the same type propeller Piper has been installing on new Malibu Mirage aircraft at the factory since 1998. Installation of the three-blade, 80 in. diameter composite propeller reduces takeoff ground roll and improves climb performance. The new system is said to also significantly reduce noise and vibration compared to the standard two-bladed metal propeller. The extra blade and a technologically advanced new airfoil are considered the major factors in this improvement. Cruise speed remains unchanged with the new propellor (Plate 4).
The Hartzell propeller is said to be the most durable propeller currently available for the Malibu, featuring three Kevlar-epoxy blades with advanced airfoils. The Hartzell composite blade structure, originally developed for the regional airline industry, has experienced millions of hours of operation in all climates. The propeller is certified to the latest bird-strike and lightning strike criteria. Installation of the kit also includes a ground lockout system to prevent blade damage resulting from the accidental operation of the de-ice system. The kit includes the 80 in. diameter three-blade composite propeller with all de-ice equipment (except airframe electrical wire), polished spinner and STC documents.

Hartzell’s Top Prop conversion kits claim improved service and maintenance benefits including a 6-year, 2,400 h TBO (the longest service interval available). The propeller also has the Hartzell Plus Three warranty,covering parts and service for up to 3 years or 1,000 h. Hartzell propeller conversions are said to offer pilots one of the easiest and most economical methods for improving the performance of their aircraft. With a wide variety of Beech, Cessna, Commander, Mooney, Piper, and SOCATA aircraft kits available, the Top Prop family represents one of the largest and most complete propeller conversion offering in the world.
