McCauley Delivers Composite Prop for Skycatcher
By J. Mac McClellan, Director of Publications, EAA 747337
September 27, 2011 – McCauley has built a fixed-pitch propeller entirely from composite materials, saving nearly 5 pounds compared to the aluminum prop originally created for the Cessna 162 Skycatcher LSA.
McCauley uses a single fiber construction technique, making the propeller strong and lightweight. The composite prop named 1L100 is 66 inches in diameter and weighs 9.3 pounds compared to the 14.2 pound weight of the aluminum prop it replaces.
The 1L100 is specifically designed for the Continental O-200D engine in the Cessna 162 and the prop will be standard equipment on Skycatcher serial number 108 and on. The new prop will be available to retrofit Skycatchers already delivered.
The 1L100 is McCauley’s first propeller certified under the ASTM standard that governs LSA production. The company has been designing and manufacturing propellers for more than 70 years and is a division of Cessna. In the early 1940s McCauley became the first to create a propeller from forged steel, a prop so tough that at least a few are still flying on Stearman biplanes.
