Systems Theoretic Process Analysis (STPA) is a new hazard analysis method developed at MIT to address a broad range of accident causal factors including dysfunctional interactions among components, design flaws, and requirements problems. This paper presentsa new extension for analyzing human interactions with automation and understanding why unsafe behaviors may appear appropriate in the operational context. The extension is demonstrated by applying it to pilot control of aircraft pitch control during stall recoveryusing scenarios from theAir France 447 accident
