## Probable cause

A loose oxygen line, which was not detected by maintenance personnel during a recent annual inspection, that allowed oxygen to escape and drain the oxygen canister more quickly than the pilot expected. This reduced the pilot's availability of supplemental oxygen and led to his experiencing hypoxia and the airplane subsequently flying on autopilot until it eventually lost power due to fuel starvation.
