## Narrative

As the FAA filed it, in capitals; the FAA replaces private details with ^PRIVACY DATA OMITTED^.

(-23)AS THE AIRCRAFT WAS BEING PREPARED FOR TAKE-OFF, THE CO-PILOT NOTICED HIGH HYDRAULIC PRESSURE ON THE LANDING GEAR. HE ATTEMPTED TO RELIEVE THE PRESSURE BUT PERFORMED THE GEAR RETRACTION PROCEDURE RATHER THAN THE PRESSURE RELIEF PROCEDURE.  THIS ACTION RESULTED IN THE LEFT MAIN GEAR RETRACTION INTO THE WHEEL WELL.

## The NTSB's investigation of this event (1)
