## Narrative

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

(-23) SHORTLY AFTER TAKE OFF FROM SAN JOSE, CA. AIRPORT (SJC) AND UP ABOUT 5000 FEET, BOTH THE PILOT AND COPILOT NOTICED AN UNDETERMINED VIBRATION COMING FROM THE LEFT SIDE OF THE A/C BEHIND THE PILOT. BOTH PILOT AND COPILOT MADE THE DECISION TO RETURN TO SAN JOSE FOR FURTHER INVESTIGATION OF THE VIBRATION. AFTER MAKING AN UNEVENTFUL LANDING BACK AT SAN JOSE AIRPORT, THE PILOT NOTED THAT A SIMILAR INDICATION HAD BEEN NOTED DURING A LANDING TWO DAYS EARLIER. THIS ENTRY WAS MADE AS INFORMATION ONLY. AMERICA WEST AIRLINE MECHANICS TRIED TO DUPLICATE THE VIBRATION BY RUNNING THE A/C ON THE GROUND, HOWEVER, THEY WERE UNSUCCESSFUL. AMERICA WEST AIRLINES STATION MANAGER MADE THE DECISION TO TAKE THE A/C OUT OF SERVICE AT THSI TIME. A DECISION WAS MADE TO SEND BACK TO THEIR HOME BASE STATION FOR A TEAM OF TROUBLESHOOTING MECHANICS WHO WERE MORE EXPERIENCED IN LOCATING SUCH PROBLEMS.

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.
