## Narrative

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

PILOT MADE NORMAL TAKEOFF FROM PORTLAND HEADING TOWARD ROSEBURG SOON AFTER LEVELING OFF (35 MILES SOUTH OF BATTLEGROUND VOR) PILOT HAD A VACUMN FAILURE AND THEN THE NUMBER 1 NAVIGATION SYSTEM HSI FAILED.  SWITCHING TO THE NUMBER 2 NAVIGATION SYSTEM HE ALSO HAD AN OFF FLAG ON THE OBS.  THE PILOT DECIDED TO RETURN TO PORTLAND AND LANDED WITHOUT FURTHER PROBLEMS.THE PNEUMATIC PUMP HAD SHEARED IT'S SHAFT.  THE NUMBER ONE NAVIGATION SYSTEM'S HSI HAD A POOR GROUNDING CONTACT AND THE RADIO FOR THE NUMBER TWO SYSTEM WAS LOOSE IN THE RACK.GOOD DECISION ON PILOT'S PART, AN INCIDENT DUE TO THE POTENTIAL HAZARD IF THE WEATHER HAD BEEN IMC.

From the FAA Accident/Incident Data System. Reports are matched to registry aircraft by N-number and event date, checked against the reported make and model; the registry's history has gaps, so older matches can be wrong. Compare the reported make and model. For accidents, the NTSB's own investigation is the fuller record.
