Sequence of events
NTSB’s coding before 2008: each occurrence and phase of flight, and the causes and factors under it. The codes are defined in NTSB’s coding manual.
Analysis
During cruise, the crew experienced a loss of hydraulic pressure & smoke in the cockpit, then donned their oxygen masks. They used the emerg gear extension system & made a safe emerg landing. An exam revealed a cracked 2000 PSI aluminum hydraulic line had sprayed fluid in the cockpit. A recently issued service bulletin recommended replacement of that line, but parts were reportedly not available. Longitudinal scratches were found along the length of the line. Failure had occurred at a longitudinal scratch at a bend in the line.
