## Narrative

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

PILOT DESCENDED BELOW MINUMUM ALTITUDE 5 MILES FROM OUTER MARKER. GLIDESLOPE INDICATOR FAILED WITHOUT WARNING FLAG.

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.
