This report provides technical guidance for complying with the fatigue evaluation requirements of Part 23 (small and commuter category airplanes) of the Federal Aviation Regulations, Section 23.572, pertaining to empennage, forward wing, and winglets/tip fins. Detailed procedures are described for developing empennage repeated loads using published airplane center-of-gravity normal acceleration spectra in conjunction with basic airplane data. An alternate approach that eliminates calculating applied loads uses empirically derived stress equations from measured flight strain survey data, coupled with the airplane center-of-gravity normal acceleration spectra and proposed airplane usage data.
