Abstract

The paper investigates the ability to learn from an aircraft accident as the opportunities for learning diminish with the decline in the accident rate. A safety compromising case is studied as the processes of aircraft accident intervention and recovery can degrade the ability of an aircraft accident investigation process to enhance aviation safety by revealing accident causation. In the case study an assessment of the Slovenian aircraft accident response system was made. For the purpose of evaluating the successfulness of aircraft accident intervention and effectiveness of recovery, a model of aircraft accident response system requirements has been developed. Based on non-conformances identified by the model of requirements, remedial measures are proposed for the enhancement of the aircraft accident response system operation. Criteria for the definition of the transition from accident intervention to recovery are derived from the assessment findings in a manner not to impede the aircraft accident investigation effectiveness and efficiency. Proučevana je sposobnost učenja na napakah, ki so povzročile letalsko nesreče, saj se število priložnosti za učenje zmanjšuje z upadanjem števila letalskih nesreč. Predmet raziskave je primer z nevarnostnim potencialom, ki predvideva, da procesa intervencije in sanacije po letalski nesreči degradirata zmožnost procesa preiskovanja letalske nesreče, da z ugotovljenimi vzroki za nesrečo poveča raven varnosti v letalstvu. Evalviran je slovenski sistem odzivanja na letalsko nesrečo. Za namen evalvacije uspešnosti intervencije in učinkovitost sanacije po letalski nesreči je pred- stavljen razvit model zahtev za sistem odzivanja na letalsko nesrečo. Na podlagi neskladij, ugotovljenih z modelom zahtev, so predlagani korektivni ukrepi, ki bodo zagotavljali, da bo sistem odzivanja na letalsko nesrečo sposoben izboljševati varnost v letalstvu. Na podlagi ugotovitev presoje pa so izpeljana merila za definicijo trenutka oziroma pogojev prehoda iz intervencije v sanacijo po letalski nesreči na način, ki ne bo negativno vplival na uspešnost in učinkovitost procesa preiskovanja letalske nesreče.
