A METHOD OF ANALYSIS FOR GENERAL AVIATION AIRPLANE STRUCTURAL CRASHWORTHINESS

Gil Wittlin, Max A Gamon

Abstract

The results of an effort to develop a method of analysis of the structural response of general aviation airplane subjected to a crash environment are presented. A review and evaluation of 8491 obtained from National Transportation Safety Board (NTSB) tapes are presented. Eighteen (18) accident cases from the FAA Civil Aeromedical Institute (CAMI) files are discussed. The performance parameters and structural design characteristics associated with 61 general aviation airplane models are used to establish several airplane categories for light fixed-wing aircraft. An accident data computer program, developed by the Cessna Aircraft Company, is presented. The requirements for performing computerized crash analysis of general aviation airplanes during probable accident conditions are described.
