PIQUA, Ohio — December 9, 1997 — Hartzell Propeller Inc. has received a Supplemental Type Certificate (STC) for installation of new two-bladed aluminum hub propellers on all early model Cessna 310s. Applicable models include the 310 through 310H, and the E310H, aircraft which employ Continental O-470-M or IO-470-D engines. The new prop will eliminate the inspection requirements of Airworthiness Directive 97-18-02.

The new Top Prop system replaces old McCauley threaded props as well as Hartzell steel hub propeller systems, some of which are 35 to 40 years old. The props will offer improved service and maintenance benefits including a 2,000 hour TBO … the longest service interval available … and a reduction in weight of approximately 8 pounds per aircraft. The kit is also available with an optional alcohol anti-ice system.

These new propellers are the latest addition to Hartzell’s growing family of “compact” propeller systems, which feature a two-piece aluminum hub design. The props feature the strongest coverage in the business … the Hartzell Plus Three™ warranty … which covers parts and service for three years or 1,000 hours. List price for the new propeller system is $12,900 or $13,900 with anti-ice. The kit includes two props, two new polished spinners as well as STC paperwork.

Hartzell propeller conversions offer pilots one of the easiest and most economical methods for improving the performance of their aircraft. With a wide variety of Beech, Cessna, Mooney and Piper aircraft kits available, the Top Prop family represents the largest and most complete propeller conversion offering in the world.
