NTSB narrative
THE ACFT CRASHED INTO A HOUSE WHILE ON AN ILS APPROACH TO RWY 11 AT HANSCOM FIELD. SHORTLY BEFORE THE ACFT HAD REACHED THE OUTER MARKER (AND AFTER THE HAND OFF FROM BOSTON APPROACH CONTROL TO HANSCOM TOWER) AN ALTITUDE ALERT ON N4467X WAS RECEIVED BY THE BOSTON APPROACH RADAR CONTROLLER. HE NOTIFIED THE HANSCOM CONTROLLER WHO THEN INFORMED THE PLT OF THE ALERT, TO WHICH THE PLT REPLIED HE WAS AT 1400 FT AND CROSSING THE OUTER MARKER. THIS WAS THE THIRD INSTANCE DURING THE FLT WHERE A DISCREPANCY BETWEEN THE BAROMETRIC ALTIMETER AND THE ENCODING ALTIMETER CAME TO LIGHT. INVESTIGATION ALSO REVEALED THAT THE ACCIDENT OCCURRED AT THE END OF AN 18 HR WORK DAY FOR THE PLT WHO HAD ALSO BEEN ILL WITH THE FLU DURING THE WEEKEND PRECEEDING THE ACCIDENT.

Source notes (4)
- Unreviewed is an editorial label, not an investigation status. API-sourced is not report-checked or human-reviewed. Explicit event totals are used without summing aircraft injury tables; onboard allocation is withheld. Unknown values remain unknown. The operation category is mapped from the NTSB-reported FAR part and has not been reviewed.
- Filled from the NTSB case API where the bulk record had no value: local date, investigation status. Values present in the bulk record are kept.
- The date is the local date; the NTSB stores the UTC date 1984-04-19.
