Hazards in the Polish Civil Aviation resulting from engines failures

Abstract

Published by the Civil Aviation Authority in May 2017, the State Safety Programme 2017-2020 in the appendix A presents "Events Data - 2016". Detailed description of the hazard arising from the technical condition of aircraft limits to the general presentation of the events in terms of SCF-NP (System Component Failure Non Powerplant) and SCF-PP (System Component Failure Powerplant). The analysis of these events performed in the Institute of Aviation (aviation events reports are collected in the European Coordination Center for Accident and Incident Reporting System database - ECCAIRS) has shown that the general aviation and commercial aviation (CAT) should be treated separately. Especially events caused by the powerplants failures must be considered separately for piston, turbofan, turboshaft, turboprop types and also their each installation has to be taken into account. Events caused by the technical condition of aircraft, especially engines, are the most common cause of accidents in general aviation. The aim of the article is to improve risk awareness and, ultimately, reduce the number of the aviation events associated with exploitation of the piston engines. Particularly significant impact on reducing the number of accidents in general aviation can be achieved by the implementation of modern technical solutions to control the technical condition of the engines and reduce their operating costs, while operators are fully aware of the risks resulting from the possibility of extending engine time on wing. In conclusion: reversing the dangerous trend of piston engine failures causing aviation safety hazards requires, above all, changes in the way these engines are operated.
