Sharing Safety Data

摘要

In the early 1990’s, the Aerospace Industries Association, in conjunction with the European Association ofrnAerospace Industries (AECMA), provided the Federal Aviation Administration (FAA) with a study aimed atrnthe development of more effective methods to identify, prioritize and resolve safety-related problems occurringrnon commercial aircraft engines. This initial Continued Airworthiness Assessment Methodologies (CAAM)rnstudy covered a variety of propulsion system and auxiliary power unit (APU) events perceived to impact safety,rnpresenting historical data on event frequency and severity at the airplane level. The information was used by thernFAA to help identify and prioritize responses to individual engine, propeller and APU safety concerns. It alsornproved vital to the development of effective safety initiatives in the propulsion community. Recently, the CAAMrnteam was re-established to update the data study with the latest information on propulsion system accidents andrnincidents.rnThe CAAM teams that developed both data studies are models of cooperative safety data sharing betweenrnindustry and airline organizations, and between those organizations and the FAA. This paper will address thernmethodology that the teams followed, the problems encountered and the development of the de-identifi ed safetyrndatabases. Additionally, the paper will provide a review of the data, covering the prevalence and relative severityrnof propulsion-related events. The reader will thus gain an understanding of the range of propulsion systemrnmalfunctions, how often they occur, and the level of threat they have posed historically.
